First of all, thanks to everyone for still following this story and for all your reviews. They always make me smile, even if I'm having a bad day.

Silvermane1 asked if we'll be seeing any interaction between the Doctor and Harry. Not yet, but yes, we'll be seeing it. It may not be too much for now, though, since I don't want the Doctor to become too domestic and all that.

TamAnTam, I share your opinion wholeheartedly. I don't want the Doctor to end up alone as he always does. Hopefully Harry will be an exception, as he always is. You'll see in this chapter. I admit I was surprised someone was reading this story from Chile and then went to my profile and saw that there was people from all over the world. It was pleasantly surprising. I suppose English is as widely spread as they say jajaja. Anyway, thank you for the review.

Pri-Chan 1410 I'm sorry for the spoilers, but I especially like David Tennant as the Doctor so I couldn't begin any other place. I hope you enjoy the serie as much as I did and I didn't make you cry too much with the last chapter.

Some of you have commented on my slow updates. I know it always takes me some time to update, but it happens with all of my stories since I'm constantly having exams in class. It's my last year in high school and everything feels a little surreal.

I know this chapter is a little shorter than the last and it's different from the others, but my story won't be only about the adventures the Doctor lives in canon. There will be more chapters like this one. I explained everything to the best of my abilities since I'm in a bit of a hurry right now, but if there's something wrong please let me now.

Again, thank you all for reading and reviewing this story and I hope you enjoy this new chapter.

Chapter 7

Harry took a deep breath, gathering every Gryffindor bit he had in himself, and started with the tale that he knew from memory. The Doctor didn't interrupt him.

"There were once three brothers who were travelling along a lonely, winding road at twilight. In time, the brothers reached a river too deep to wade through and too dangerous to swim across. However, these brothers were learned in the magical arts, and so they simply waved their wands and made a bridge appear across the treacherous water. They were halfway across it when they found their path blocked by a hooded figure.

And Death spoke to them. He was angry that he had been cheated out of three new victims, for travellers usually drowned in the river. But Death was cunning. He pretended to congratulate the three brothers upon their magic and said that each had earned a prize for having been clever enough to evade him.

So the oldest brother, who was a combative man, asked for a wand more powerful than any in existence: a wand that must always win duels for its owner, a wand worthy of a wizard who had conquered Death! So Death crossed to an elder tree on the banks of the river, fashioned a wand from a branch that hung there, and gave it to the oldest brother.

Then the second brother, who was an arrogant man, decided that he wanted to humiliate Death still further, and asked for the power to recall others from Death. So Death picked up a stone from the riverbank and gave it to the second brother, and told him that the stone would have the power to bring back the dead.

And then Death asked the third and youngest brother what he would like. The youngest brother was the humblest and also the wisest of the brothers, and he did not trust Death. So he asked for something that would enable him to go forth from that place without being followed by Death. And death, most unwillingly, handed over his own Cloak of Invisibility.

Then Death stood aside and allowed the three brothers to continue on their way, and they did so, talking with wonder of the adventure they had had, and admiring Death's gifts. In due course the brothers separated, each for his own destination.

The first brother travelled on for a week or more, and reaching a distant village, sought out a fellow wizard with whom he had a quarrel. Naturally with the Elder Wand as his weapon, he could not fail to win the duel that followed. Leaving his enemy dead upon the floor, the oldest brother proceeded to an inn, where he boasted loudly of the powerful wand he had snatched from Death himself, and of how it made him invincible.

That very night, another wizard crept upon the oldest brother as he lay, wine-sodden, upon his bed. The thief took the wand and, for good measure, slit the oldest brother's throat.

And so Death took the first brother for his own.

Meanwhile, the second brother journeyed to his own home, where he lived alone. Here he took out the stone that had the power to recall the dead, and turned it thrice in his hand. To his amazement and his delight, the figure of the girl he had once hoped to marry, before her untimely death, appeared at once before him.

Yet she was sad and cold, separated from him as by a veil. Though she had returned to the mortal world, she did not truly belong there and suffered. Finally the second brother, driven mad with hopeless longing, killed himself so as truly to join her.

And so Death took the second brother for his own.

But though Death searched for the third brother for many years, he was never able to find him. It was only when he had attained a great age that the youngest brother finally took off the Cloak of Invisibility and gave it to his son. And then he greeted Death as an old friend, and went with him gladly, and, equals, they departed this life."

A few seconds of silence hung heavily over them after he finished recalling the tale.

"A little creepy for a bedtime story, don't you think?"

Harry didn't say anything.

"Okay, so what's that to do with anything?"

"At the end of the war, things were bad. We started to get desperate as the Death Eaters, Tom's followers, started to gain ground. It was then that I came across a reference to three very powerful objects and that led me to the story of the Three Brothers. Somehow, I knew the Deathly Hollows existed. I searched for them in the hopes that they would help defeat Tom. I managed to find all three of them. Since the Potters were the only direct descendants from the third brother and I am the last Potter, I was able to claim the Hollows and use them to end the war. Later I tried to get rid of them but they would just return to me. I am, officially, the Master of Death."

There was a small silence in which the only sound heard was made by their breaths.

"What… what does that entail?"

There was something strange in the Doctor's voice when he asked the question quietly and Harry didn't dare look at him as he answered.

"I can feel when someone dies or when someone is dying and, if I want to, I can know everything about a person, since the date they were born, the date they are supposed to die, and any of their deepest and darkest secrets. There's nothing that can be hidden from Death, after all. And…" Harry wringed his hands nervously and the Doctor carefully took them in his own hands, hoping to help calm the wizard. "I-I can't. I-"

"Harry, Harry, look at me." muttered the Doctor crossing the distance between them and taking his head between his hands. "I would never leave you. I won't send you away. You are not a freak. You are my special little wizard. And nothing you ever say or do would ever make me love you any less. I want you, by my side, forever."

Harry's eyes were wide with shock and filled with tears.

"You- you don't know what you are saying. Forever… forever is a very long time. You think you lo-"

"No, Harry, listen to me." interrupted the Doctor looking him in the eyes. "I know how long eternity is, I'm a Time Lord, remember? I know perfectly well what I'm saying. I love you. I think I've loved you since I first met you, even if I didn't realize it at the time. Nothing will ever change that. I know it. I love you, my precious little treasure."

Harry looked him in the eyes. He couldn't believe what he was hearing. Since he was a small child, his dream had always been to find someone to love and be loved in return.

Without knowing, he had fallen for his Doctor every time they met. His deepest desire had always been to be loved by the Doctor but he had known it would never be possible. He had always known the Doctor was different, special, and too good for him.

But looking in the eyes of the Time Lord, those eyes so full of, dare he say it, love. How could he believe it to be a lie? And his heart ached so fiercely for it to be true. He wanted, no, needed, to believe it. And it wasn't as if the man had ever lied to him.

Without even noticing, the wizard began to talk, still looking in the warm eyes of his Doctor, and the man listened quietly.

"We were desperate. Tom had used a Dark Magic ritual to split his soul in seven pieces and conceal them in objects. It was his way of ensuring his immortality. A soul cannot pass onto the afterlife if it is anchored to this world. We destroyed those objects in order to make him mortal again. Then, I discovered the seventh piece was inside my scar, the one he gave me. There are only three ways to destroy a Horrocrux. One of them is basilisk venom, another fiendfyre and another is the Killing Curse. All of them destroy the recipient." the Doctor looked worried about what he was hearing. "During the final battle, I let Tom kill me." The Doctor's eyes opened impossibly wide. "I thought it was the end. There was nothing else I could do. And, then, I awoke again. I was in the same clearing. Breathing. And alive. And the Hollows were assimilated into my core."

For a moment, nothing was heard after Harry finished talking before the Doctor took a deep breath.

"Does that mean that you are…?"

"I don't know. It could be. No one has ever had the three Hollows at the same time and no one has ever been so rightfully their owner since the Three Brothers themselves."

The Doctor didn't move and didn't say anything and Harry closed his eyes, resigned to be rejected. He opened them again when he felt two big warm hands carefully cupping his cheeks. He was shocked when, instead of rejection, he only saw love and wonder in the other's eyes.

"You do not understand what that possibility means to me, do you? All my life I've met people I knew I would, sooner or later, loose to Death. The mere thought of living without you… I don't think I would be able to do it, Harry. And now you're telling me it may be possible I will never have to go through that. That you may stay with me forever or at least for as long as you want. It's that which made me afraid of what I felt for you; the thought of not knowing what I would do if I ever lost you. I tried to keep away when you were a child, but I couldn't. You were already so brilliant. So captivating. I couldn't keep away even if that meant someday I would be following you to Death's arms. I love you, my Harry. I love you so much. You do not realize how much this means to me."

Tears flowed freely down both their cheeks while Harry shook with barely supressed emotions.

"I'm afraid, Doctor."

"I know. I would be too if I were in your place. But I promise you this: I will be here for you. Forever."

And looking into his eyes, Harry believed him. How could he not? And suddenly, the thought of immortality didn't sound so bad. Not if it allowed him to have eternity with his Doctor. Not if it allowed him to avoid hurting the Doctor with his own passing.

The wizard nodded and the Doctor beamed at him before, slowly, leaning in and giving him a chaste kiss on the lips.

"Perfect. And now, I think it's time for us to eat something and go to bed. It's been a long day filled of excitement."

All worries forgotten, Harry laughed as the Doctor hopped around, sending the TARDIS to whoever knew where, before directing him to the kitchen.

HPDWHPDWHPDWHPDW

Harry stood awkwardly by the door. Now that he knew it was the Doctor's bedroom, he couldn't help but see it in a new light.

The room was made in warm colours and sparsely decorated, with a few trinkets here and there. It was obviously a place he didn't use often.

The man stood in the middle of the room rubbing the back of his head and looking around as awkwardly as Harry felt.

"I know it's not much…"

"Doctor, it's okay. It looks… cosy." said Harry honestly. "I like it."

"You do?" asked the man with evident surprise.

Harry nodded. Even though it was evident that the Doctor didn't sleep there usually, probably just falling asleep in the library or even the pool, it still had that touch of personality that reminded him of the Doctor.

"Well, we should… ah… we should go to sleep." said the Doctor.

Harry nodded again. He blushed and bit his lip as he saw the Doctor take off his trench coat and lay on the bed without bothering with his clothes. Harry followed as he was also too tired to care for the clothes.

The Doctor took out his screwdriver and pointed it at the switcher. The lights went out. Harry lay on the bed with his eyes closed, trying to concentrate on his breathing so he would fall asleep.

He soon found out he wasn't the only one having problems to sleep when he felt a hand touch his and the Doctor entwined their fingers.

The wizard smiled and, after hesitating, rolled to the side and put his head on the man's shoulder. The hand grabbing his squeezed and the human squeezed back.

With the unfamiliar breathing of another, it took them less than they thought it would to fall into Morpheus' arms.

HPDWHPDWHPDWHPDW

They fell from the bed.

The Doctor and his companion were abruptly awoken by the TARDIS shaking and found themselves falling from the bed.

They looked at each other in worry and confusion before the Doctor jumped up and run out of the room, taking his trench coat in the way.

Harry smiled fondly and looked around for his own jacket before running after the Time Lord. At least this, whatever it was, had spared them the awkwardness of the first time waking up in the same bed.

When he finally arrived at the control room, the Doctor was already fumbling with the buttons.

"Doctor! What's wrong?" asked Harry gripping the railway to stop himself from falling. "What's happening to the TARDIS?"

"I don't know." answered the man gritting his teeth and pushing another lever.

The TARDIS gave another forceful jerk and Harry fell to the floor. The next jolt sent his head against a pillar and a soft moan left his lips.

Finally, the spaceship stopped and the Doctor hurried to his little wizard's side.

"Harry! harry, love, are you okay?"

The man stopped him from trying to stand up by pushing his shoulders gently to the floor.

"Where does it hurt?"

"My head. I hit it against the column." answered the teen feeling a painful throb in the back of his head.

"Let me see." muttered the man carefully touching his head.

"It's okay, Doctor, it's just a blow. Nothing to worry about."

But the Doctor insisted in examining him and, knowing how stubborn the man could be, the wizard let him. And, maybe, the warmth that his worry caused in his chest had a little of influence too.

"Okay, it won't cause you any trouble." finally sighed.

His little one smiled at him and gratefully accepted his help to stand up. The Time Lord caressed his cheek softly and kissed his forehead.

"Where are we today, Doctor?" asked his human sweetly.

The man frowned and looked at the screen of his TARDIS.

"I'm not sure. It seems to be somewhere on Earth, maybe even near Britain, but I can't specify more. Something's blocking the TARDIS."

"What could be powerful enough to interfere with the TARDIS?" muttered Harry frowning a little too.

"I'm not sure but whatever has that power it's big and dangerous." said the man. "I can't even say what time we're in. Only that it's in the 20th century." the man's serious expression morphed into a mischievous one. "Want to take a look outside?"

The teen returned the impish smile and nodded eagerly. The Time Lord walked to the door and opened. He was pretty disappointed to find himself in the middle of nowhere, though that emotion quickly disappeared when he looked to the side and saw his companion's wide eyed look.

"Harry?"

"I had hoped I would never get to see this place in person." shivered the wizard.

He knew then what had interfered with the TARDIS. The wards.

"It's just a rock in the middle of the ocean." said the man in confusion.

"You can't see it?"

"See what?"

"Take my hand." instructed the teen.

The Doctor did as asked and felt something was over him before the scenery in front of him changed. What he had thought was just a rock turned into an island made of bare stone. The waves crashed violently against the shore and the sky was a dark grey, covered by clouds.

The most astounding thing was an imposing building made of stone that stood not too far from where they had landed.

The Doctor walked forward a few steps, ignoring the cold of the wind slowly seeping into his bones.

"Doctor, we need to return to the TARDIS."

"Why? Where are we?"

"We're in…"

"Hey! You two! Stop right there!" shouted someone running towards them.

A moment later, two men with red robes were pointing wooden sticks at them. The Doctor soon realized those weren't sticks but wands and, as Harry's war reflexes once more kicked in, his was pointed at one of the men.

"This place is restricted to everyone not authorized by the ministry. Lower your wand or we'll be forced to stun you!" shouted a man.

His little wizard quickly did as told and waited to speak till the other two stopped.

"Excuse us, aurors. We didn't notice we had entered a restricted area." tried Harry.

"So you didn't notice Azkaban is a restricted area?" asked one sceptically.

"No! I mean, yes! We know Azkaban is restricted, but we didn't notice we were here." hurried to say the teen.

"How did you get here, then?"

The young wizard tried to come up with a lie. The Doctor didn't know enough about Azkaban, just that it was a wizarding prison, so he wouldn't be of any real help. Thinking of that, the wizard said the first thing that came to his mind.

"We were trying a new prototype of transportation device. You know the problems the flu net poses to families with children, so we're trying to create something more similar to the vanishing cabinets but able to connect on a wider net." explained Harry very quickly. "See that blue box back there? That's the prototype. We were just trying it and somehow found ourselves here."

The wizards blinked.

"That's a police box." Oh, so at least one was a muggleborn or halfblood wizard. "And there are antiaparition wards around the all Azkaban."

The teen contained a curse and glanced at the Time Lord. Without knowing the date, he couldn't risk being recognized.

"The idea of the police box comes from the muggle entrance to the Ministry. We think it'll look less suspicious to the muggles, though I have no idea of how we got here. The device wasn't supposed to trespass any antiaparition ward."

The wizard himself was surprised at the idea he had had, though he wasn't very sure if they were credible. The two wizards seemed uncertain and glanced at each other, not knowing what to do.

"We'll take you to our official." decided one of them. " You'll have to give us your wands."

Harry hesitated. It wasn't only that he didn't want to give up his beloved wand, but he didn't want them to try verifying his story when he didn't know even the date.

"That's not necessary. Really. We can just return to the box. Maybe it'll work…"

"No, you're coming with us. And your box too." said one of the wizards pointing his wand at them.

The Doctor lifted his arms in a slow pacifying gesture.

"We don't want trouble."

"Then give us your wands and follow us." said the same wizard.

The younger wizard obeyed and with slow movements gave up his phoenix core wand. He didn't like it. He didn't like it one bit, but he had no other option. Stunning them was possible, but one of them would be able to cast at least a hex and he didn't know if he would be fast enough to protect the Doctor from it.

"What do we do with the box?" asked the one knowledgeable on muggles.

"Shrink it. We'll carry it with us." ordered the other.

Harry's eyes widened a fraction. They couldn't allow that. They still didn't know how the TARDIS would react to so much magic directed at it and they weren't eager to find it out now.

"Wait, you can't do it! The magic levels of the device are erratic now from the trip. If you cast any magic over it, the structure is unstable enough to explode. You could kill us all."

The auror hesitated at that and, finally, decided to leave the TARDIS there. The Doctor and the teen sighed in relief. It hadn't been a complete lie, after all. Technology often exploded in contact with magic.

"And your wand?" asked to the Doctor the auror that seemed in charge.

"Eh, I… I don't have one." answered the Time Lord a little hesitantly.

"You don't have one?" frowned the auror.

"His wand broke when we landed here. Excuse him, his still a little confused from the unexpected broken bond. The landing was rougher than we had expected. I suspect it were the wards."

The aurors nodded, looking sympathetically at the time traveller, and the man tried to look sad at the fictitious loss.

"Okay, come." ordered the leader.

The two travellers shared a look and did as asked. The four of them started to walk in the same direction, leaving the TARDIS behind.

"So, can we have your names?" asked the Doctor casually.

"Oh, yes, sorry." The younger of the aurors cleared his throat. "I'm auror Mitchel Johnson and this is auror senior Richard Thompshill."

"Muggleborns or halfbloods?" asked Harry with real curiosity.

"Does it matter?" growled Thompshill.

"No, not really." hurried to say the wizard. "I'm a halfblood myself."

He hoped the admission was enough to calm the man. He didn't have prejudices.

"I'm a halfblood too." admitted the auror relaxing a little.

"I'm a muggleborn." said Johnson.

They lapsed into a strange silence. Even the Doctor remained silent as they walked. The Time Lord used those moments to study the two wizards.

Mitchel Johnson was a young man that radiated energy. He had light brown hair, almost the colour of sand, clear blue eyes and a square jaw.

Richard Thompshill looked to be in his early forties and had the wary look of a man that has seen many horrors, and both Harry and the Doctor knew what they were talking about when they said that. He had dark hair that had begun to turn grey at his temples and dark eyes.

Out of nowhere, a cold sensation started to seep into their bones and dark depressing emotions clouded their minds.

"Dementors! They weren't supposed to be in this sector!" shouted Johnson.

"Give me my wand, auror." tried Harry when the dark figures appeared on sight and his breathing sped up.

But it was too late. The beings had reached them too fast. And the auror refused to return the teen's wand.

A feeling of wrongness overcame Harry. There was something wrong, so wrong. He had had a bad feeling when he first saw Azkaban but now that he saw the dementors it seemed stronger. And the sensation came directly from the magic of the Hollows.

The Doctor saw in slow motion as his emerald collapsed on the floor and went to catch him but the aurors, unable to create a patronus with so many dementors nearby without a warning, caught him by the arms and forcibly dragged him away.

"No! No, wait! You can't abandon him! We can't-"

They stopped a short distance away when the dementors didn't follow them, seemingly more interested in the dark haired boy, and the Doctor tried to run towards them only to be stopped again by the aurors petrifying him.

"Stay put! We're going to create a patronus."

By the time that happened, Harry was already surrounded by the soul-eating beings. One of them hovered over his unconscious body and they saw in horror as it caressed his pale face.

Wherever the creature touched him, the skin tinted black and the colour disappeared after a few seconds. What confused, and honestly also scared, the aurors was that the dementor wasn't even trying to Kiss the teen. Had the boy died of horror and that was why the dementor couldn't eat his soul?

The aurors' patronus charged forward and the dementors disbanded. Furious, the Doctor glared at the two aurors that were looking at the teen with wide eyes.

Thompshill approached slowly and knelt down to take his pulse.

"He's alive!"

The auror seemed surprised, amazed even, and the Time Lord glared harder. He couldn't move but his heart was racing and his emotions were running all over the place.

"You can release him, Johnson." said Thompshill looking at the man.

The Doctor felt his muscles relax and jumped to his feet before running towards Harry, ignoring the shaking of his legs and the rest of his body. He knelt down besides his little one with concern and lifted his head to put it on his lap, sweetly putting a black lock after his ear.

"Harry." called. "Harry."

"It's the first time I see someone react so strongly to the dementors." commented Johnson.

"I've seen it in people with great horrors in their past." said solemnly Thompshill. "We need to get inside. We still don't know what so many dementors were doing here."

The Doctor nodded and scooped up his still unconscious little one, concerned again at his light weight. He walked alongside the two aurors in the stone building's direction wondering if his own mild reaction to the creatures was because of him being a Time Lord.

HPDWHPDWHPDWHPDW

His head hurt and his eyelids felt heavy, but he still managed to open them. The first thing he saw was a handsome concerned face; the handsome and concerned face of his Doctor.

"How are you feeling?"

Harry blinked and then frowned. What had happened? The last thing he remembered were… cries. Very familiar cries. His mother's cries.

"Give him this." said a new voice.

The wizard turned his head and saw a man in crimson robes with a black insignia in the chest giving something to the Doctor.

"Chocolate?" wondered the Time Lord.

"It combats the effects of the dementors." explained Harry reaching for it himself.

"Really? Chocolate? I knew it was good, but…"

"Honestly, what are they teaching them at school nowadays?" muttered very low the unknown man. "If we're finished with the lesson… My name is Tom Rogers and I'm the auror in charge of Azkaban. Now I want to know who you are and what you are doing here."

Harry bit the chocolate and sat with the help of the older time traveller. Looking around he noticed they were in a badly lit but spacious room.

"I'm Harry Smith and this is the Doctor." lied the teen.

The Doctor nearly snorted in amusement when his little one said the surname.

For his part, the wizard had remembered that he had said he was a halfblood so he had thought of a surname that could be both muggle and wizarding.

He had remembered that Smith was a common muggle surname besides a not very famous but really big and known wizarding family. Zachariah Smith was one of them.

"The Doctor? Doctor who?" asked Rogers.

"Just the Doctor." Smiled the man amused. Yes, definitely just a thing of his little Harry.

"Well, 'Just the Doctor', what are you and Mister Smith doing in Azkaban?"

Harry gave the same explanation as before and waited for the auror's reaction. That reaction, though, came from an unexpected source.

"Auror Rogers, could you and your men gives a few minutes of privacy?" the new and rough voice articulated it as a question but it was very obviously an order. And as any person in their right mind, he didn't question him.

Harry froze at that voice. Lying had just become a nearly impossible thing. The teen looked over to a shadowed corner and his suspicions were confirmed. He cursed himself for not noticing him before.

"Now, 'Mister Smith'," started Alastor Moody. "care to explain how you got here? The real version this time."

The wizard blinked and kept his gaze on the old wizard. Was it his imagination or he looked slightly younger?

"Harry?" muttered lowly the Doctor.

"What year is it?" asked abruptly the teen.

"Time travellers."

Harry froze again at his past, or technically future, professor's words. This time the Doctor did the same.

"W-what?"

"You just confirmed my theory." stated the old auror.

"How?" asked the Doctor fascinated, not only by the man's statement but by his grotesque appearance too.

The younger wizard just sighed and listened when Mad-Eye looked at him and explained with a smirk.

"Did you really think I would believe that story about the prototype? The Ministry hasn't approved of any experiments of that kind recently." Damn his bloody contacts in the Department of Mysteries… "And, Smith? Really? Do not insult my intelligence."

"I wouldn't dream of it, sir." said the teen with a light but honest smile. "So what gave us away?"

Moody looked him in the eyes for a few seconds before nodding to himself almost imperceptibly.

"First, your appearance. Your features are very distinctive from two prominent pureblood families. Second, you wear those families' rings and you cannot wear them if you're not of their blood. And," continued the wizard before the Time Lord could interrupt him. "I know for a fact that every member of those families is either dead or in a cell in this same building. All but one."

"And?"

"Right now he's a five year old child."

Harry blushed a little.

"First, what rings are you talking about?" asked the Doctor aloud. "And, second, good deduction."

"The rings are under a glamour." explained Harry. "It's a spell that allows a person to hide or change little things. Moody's crystal eye allows him to look through the glamour and see the rings."

"Just as I can see that scar in your forehead, hidden behind your fringe." added the auror gruffly. "I don't want you to confirm anything, but I'm pretty sure I know who you are and the only explanation for it is…"

"…time travel." finished Harry with a sigh.

"Exactly. From now on, try and follow the laws of time travel —at least you learned them in class, didn't you? — and don't reveal too much about the future. We don't need a paradox in top of everything."

Harry bowed his head and nodded meekly.

"Yes, sir."

"Harry, who is he?" asked the Doctor.

"Oh, sorry, Doctor. This is auror senior Alastor Moody. Alas- Auror Moody, this is the Doctor."

Both men's gazes sharpened at his slip`, but they let that pass in order to assess each other.

"So, what date are we in?" wondered the teen nervously, breaking their staring match.

"November 9, 1985." answered the old auror. "What did you come here for?"

"Oh, nothing in particular." said the Doctor with his habitual enthusiasm. "We were traveling a little, you know, visiting Egypt during Cleopatra's reign and Rome during its fall, when we appeared here."

"So you travel through time for… entertainment?" drawled the auror with distrust.

"Yes, you could say that." conceded the Time Lord a little grudgingly. "So, what's happening here?"

"Who says anything's happening?" retorted the older wizard.

"You said before, and I quote: 'We don't need a paradox in top of everything'; which implies there's something already causing you trouble and you're on high alert…"

"Constance vigilance!"

The sudden outburst from the two wizards made the Doctor jump and his teen giggled. The older wizard seemed to smile, though the Time Lord couldn't be sure with all the scars on his face.

"Alastor is always on high alert." explained the youngest of them still laughing and not realizing his slip.

"A little paranoid, aren't you?"

"It's not paranoia if they're really out to get you." spoke the two wizards as one.

"That's a little creepy." whispered the man.

The younger traveller blushed deeply and the auror observed him speculatively.

"Back to the topic at hand… what's going on here? What are you doing in Azkaban?"

"Why should I tell you?"

"Because I know you're not supposed to be here and we may be able to help." stated Harry very seriously.

The auror remained silent for a minute, looking the teen right in the eyes, and the Doctor fidgeted uncomfortably at the intensity of his gaze.

"Which hex did Abraxas Malfoy use when he took my eye in battle in 1945?" asked suddenly the auror.

"That's a trick question. There are no records of the Death Eater attacks." muttered Harry looking at the man with a slight smile. "It wasn't a hex but a piece of debris." the old wizard narrowed his eyes, but the teen continued before he could interrupt. "And it was against Evan Rosier that you lost your eye in battle in 1979, just before Voldemort's fall. Abraxas Malfoy cut out your leg in 1945 but a healer was able to reattach it and it was Lucius Malfoy during a surprise Death Eater raid that cut it out permanently in 1967."

The Doctor looked from one to the other as they stared into each other's eyes. The two wizards seemed to be waiting for the other to look away. The Time Lord wasn't ashamed to admit he felt proud when Moody was the first.

"So… what's going on here?" drawled the time traveller.

Harry looked at him from the corner of his eye before fixing his gaze firmly in the auror.

"The Ministry was alerted by the aurors here that there was an anomaly between the dementors." informed the man.

"An anomaly?"

"The dementors are…?"

The auror's sharp gaze narrowed at him before turning to Harry.

"Tell me you didn't come here with a muggle." barked the old wizard.

Harry remained stoical under his gaze and raised his chin.

"Would there be a problem if that were the case?"

"Of course there would! Not only are you breaching the Statue of Secrecy…"

"I'm exempt from it."

"…but you're putting a defenceless muggle at risk!"

The younger wizard flinched at that and the Time Lord frowned before putting an arm around his shoulders.

"I'm not defenceless and I'm not a muggle."

"Are you a wizard, then?"

"No."

The auror frowned at him.

"A squib?"

"No."

"A magical creature?"

"No. I don't have magic. Not a tiny bit."

The auror looked at him for a while before deciding to change the topic.

"Then you're defenceless. Against the dementors." added.

"And the dementors are…?" insisted the man.

"The creatures that attacked us outside."

"Those skeletal figures clothed in black cloaks?"

Harry smiled inwardly. It seemed the Doctor was at least able to see them. He had feared he wouldn't, since his cousin hadn't been able in the summer after his fourth year.

"Yes, they are blind but they can sense and feed on their victims' happiness. They can also Kiss their victims, which means that they literally suck the soul out of their bodies. And they guard Azkaban."

"They don't sound friendly."

"They're far from friendly, but they're under the Ministry's control." said Mad-Eye. "For now."

"For now?" asked the Doctor.

"During the war the dementors sided with Voldemort." explained Harry.

Moody didn't comment on his use of the Dark Lord's name for a second time.

"That's bad."

The auror snorted at the man's words.

"Well, at least being a muggle means it's impossible for him to be Crouch."

"He does look a lot like him, but he has no relation at all with Barty Crouch Junior." assured Harry not having noticed before that there was the risk Moody would confuse them.

Though he supposed his crystal eye noticed some differences between them. Moody hummed a little in response.

"So what's the problem with the dementors? What's that anomaly you were saying…?"

The door being opened interrupted Harry's questions and they all looked in that direction.

"Auror Moody, it's happening again!"

It was a new auror who shouted this and the old wizard stood up, limping fast towards the entrance. The Doctor and his wizard shared a look and followed after the others.

"Auror Moody, what's going on?"

They found themselves in a dark corridor carved in the stone with seven aurors. Three of them were Thompshill, Johnson and Rogers, but they didn't know who the others were.

"Are you capable of creating a good enough patronus?" asked Moody.

"Yes, a corporeal patronus." assured Harry.

"Against a dementor?"

"Against as many dementors as there are." replied the young wizard firmly.

"Then, I'll take you up on your offer of help."

The other auror raised his eyebrows at that. Moody wasn't known to accept help easily, even less from an unknown source.

"Maybe then you could tell auror Johnson to give me my wand back."

Moody frowned and signalled the man to do just that. Just before Johnson gave him his wand, auror Rogers stopped him.

"Are you sure, Moody?"

"Yes, I'm sure, Rogers. Now give him his wand."

Auror Johnson did as ordered and Harry gratefully took it. For a brief moment, relief was clear across his face and the other wizards smiled knowingly, making him blush.

"What?" asked the Doctor in a whisper.

"For a wizard, being separated from his wand is like being apart from a piece of himself." the Time Lord looked at him in confusion and the younger time traveller tried to find a comparison he would understand. "It's as if you're separated from the TARDIS."

The man winced in sympathy. He understood that too well.

"What section did you find it in?" asked Moody to the auror that had alerted them.

"The minimum security cells." answered the auror readily.

"Did you clear them from dementors?"

"Yes, sir. I sent some to patrol the island and the rest to the maximum security cells."

The old wizard nodded and started to walk down the corridor. The others followed.

"How are you feeling?" asked the Doctor lowly.

"What?"

"After the dementors and, you know, fainting."

"Oh, that." Harry blushed and the man smiled in amusement, though there was worry in his eyes. "I'm fine. The chocolate helps a lot."

The Time Lord maintained his gaze for a few seconds before nodding with clear relief and kissing his forehead.

HPDWHPDWHPDWHPDW

"What's that?" asked Harry eyeing the black bundle on the floor.

"A dead dementor."

The wizard's head shot up at that and he fixed Mad-Eye with an incredulous stare.

"A dead dementor? The dementors can't die." exclaimed Harry.

"There's never been a recorded case of one dying," agreed Moody. "but this one is dead."

"Has it happened before?" frowned the youngest wizard.

"Last week died three. The Ministry's worried and sent me here to investigate. They want to know what's causing this and how to control it."

"You mean to stop it."

"No, I mean control it."

"Why?" wondered the Doctor.

"Because having a way to kill them would give the Ministry more power over the dementors." explained Harry before any of the wizards could.

None of the aurors tried to deny his words and the Doctor found his expression mirroring Harry's dark one. Moody cleared his throat and continued.

"So you don't have any idea of what is causing this?"

"How would they know?" asked one of the aurors.

Moody ignored him and continued looking at the two.

"No. I've never heard anything even similar to this." was the teen's truthful answer.

The old auror nodded, already expecting that.

"Do you mind?" asked Harry pointing at the black bundle.

"Go on."

The wizard approached the dead dementor and placed a hand over it, closing his eyes. A frown appeared on his beautiful face.

"What?" asked Moody.

"The magic is gone."

"It's dead, of course its magic is gone." said one of the aurors rolling his eyes.

"First, it's a he, not an it. Dementors are living breathing creatures and deserve respect just like any of you. And, second, the magic is completely gone. When a magical being dies, the magic doesn't just disappear. It takes days, weeks if the being is powerful enough, for the magic to leave the body. That's why our corpses don't start to rot as fast as muggles' and why it's possible to create inferi." informed the younger wizard.

"And how do you know that?" sneered the same man.

"Because I'm magic sensible. I can see and feel magic."

That shut up the other, who grumbled and looked away. The Doctor was amazed at the things he was hearing, though he had many questions too.

"So this dementor should have some magic left?" asked gruffly Moody. "What do you think this means?"

The other aurors were stunned. It was unheard of Moody ever asking advice from others.

"Well, if it were any other creature, I would say he was killed by a 'Killing Curse'. However, we're talking about dementors. They are beings made purely of Death Magic and the 'Killing Curse' is no more than a blast of Death Magic. It would make them stronger instead of killing them by stripping them of their magic. I'm not sure what else could do this." sighed the teen.

"So we're still like at the beginning." said the auror from before with a sneer.

"At least he's trying to help; what are you doing?" answered the Doctor scowling at the man.

The auror took out his wand and pointed it at the Time Lord. In a second, Harry was in front of him, ready to put up a shield. It wasn't necessary, however, as another auror, this time the only woman of the group, stopped him by grabbing his wand arm.

"You're an auror, Cray. Behave like that." ordered harshly.

"Shut up, Greengrass. As if a dark witch like you could…"

"You shouldn't continue that way, Cray." warned darkly the Head Auror.

"Greengrass?" asked Harry surprised.

"Cassandra Greengrass. And you are?"

Harry was stumped. This was Cassandra 'Cassy' Greengrass? This was the woman that inspired the future Greengrass Heir into becoming an auror? This was Daphne's aunt? But hadn't she..? the teen's eyes widened incredibly.

"Oh, oh, sorry, eh, yeah, I'm Harry, Harry Smith, and this is the Doctor."

"Doctor who?

"Just the Doctor." answered the Time Lord with a wide smile.

She raised an eyebrow but didn't comment.

"Moody, do you think I could have a look at the other bodies? If you're keeping them, of course." asked Harry.

"Are you crazy? What do you want a dead dementor for?" asked Cray.

"What would he want it for? He wants to check if they have any magic left." said the Doctor looking at the auror as if he were idiot simply for asking.

HPDWHPDWHPDWHPDW

They entered the stone room — honestly, the Doctor thought they should try something more original. There should be a law forbidding them from making more than a quarter of the prison of stone. Maybe he and Harry could try and convince them of that later…

They saw as auror Cray levitated the dead dementor onto a table without any care, getting a glare from Harry that he ignored.

"Here's the body of the last dementor that died, two days ago." Moody signalled to the next table.

"And the other two?"

"They were taken by the Department of Mysteries."

"The Department of Mysteries?"

"It's a secret sector within the Ministry. They are like high level scientists. They dabble in every branch of magic, studying everything they come across and recording it. Although seeing as some of those things are too dangerous for the rest to know, they have to keep many of their discoveries a secret. Hence the name" explained Harry.

"I understand. What do you think they will do with the bodies?" asked the Doctor curiously.

"First, see if they can discover what killed them. Then see if they can be of any use in areas like potions or the like."

The Doctor didn't have time to ask anymore as the wizard approached the new body and run a hand over it, closing his eyes.

"It's empty. No magic at all left." sighed. "It's a wonder it hasn't started to rot yet. Wait, do dementor corpses rot?"

"We didn't want to risk it so we put them under a stasis spell." said Moody.

"Oh, that's what's surrounding them!" exclaimed Harry before the Doctor could say anything.

"So we are now like in the beginning. We don't know what is causing this and have no idea where to begin searching for answers."

Nobody said anything. What Cray was saying was true.

"Did anyone see how the dementors died? Were there any witnesses?"

All the wizards turned to the Doctor and blinked.

"What?"

"That's… that's actually a great idea." said Harry slowly.

"Yeah, I have lots of those." answered the man with a smirk.

"Oh, don't get cocky." rolled her eyes Cassandra.

Harry laughed and the man pouted at the woman. She winked at the laughing wizard while the others looked on with amusement.

"Okay, so… were there any witnesses, auror Moody?"

"Auror Randall and I were there when it happened today, sir." said a blond auror stepping forward to his senior.

"Did you see something?"

"No, sir." answered the other. "The dementors were just passing by the cells when we heard something. We turned around and saw the dementor falling to the ground. The detection spells didn't find anything unusual and we called you immediately."

"You didn't see anything unusual? Anything at all?" asked Harry with a frown.

"No, nothing."

"And nobody else saw it the other times?" inquired the Doctor.

"Well, some of the prisoners did." admitted Johnson hesitantly.

"The prisoners?"

"Yeah, in the maximum security cells." said Greengrass.

"Did you talk with them?" asked the Doctor.

The aurors exchanged glances and shook their heads. The man frowned.

"Why not?" asked Harry.

"It's the maximum security area. We try not to talk too much to the prisoners there."

"So you just ignore a perfectly good lead? Wait, don't answer that." sighed Harry. "Okay, we need to go there and talk with the prisoners."

Moody nodded slowly, looking around.

"Very well, Cray, Stain and Thompshill, you stay here. The others are coming with us."

Everyone nodded in understanding, although Cray was scowling at the old auror.

"You're not going to listen if I ask you to stay here, are you, Doctor?"

"Hell, no." laughed the man.

Harry sighed but shook his head in fondness.

"Okay. Let's go see what our unfortunate witnesses have to say."

HPDWHPDWHPDWHPDW

"Harry, why are they all so scared of the prisoners in the maximum security zone?" asked the Doctor very low.

"The wizards and witches in those cells are the worst kind you could ever find. Many are murderers and rapists and most of them are Death Eaters."

The Doctor looked at him with seriousness. He was worried that it would hurt Harry having to do this. He didn't know many details about the war, but he had a hunch that Harry had been in the middle of it all.

They arrived at the area they had been intending to without any problem, with the patronuses of the aurors gliding at the front. The crazy cackles and shouts for mercy let them know it.

Harry supressed a shiver and gulped, looking at the Doctor from the corner of his eye. The man looked sombre as he looked around at the infrahuman conditions of the cells.

"This won't last forever, Doctor." whispered Harry making sure nobody else heard them. "In my time, Azkaban is not like this anymore. The dementors don't feed on the prisoners freely. When a prisoner enters Azkaban a copy of their memories is put into a pensieve, an object used to store and review memories, and the dementors feed only from the pensieves. Also, the cells are more like tiny rooms than real cells. It is not as bad as it is now. We made sure of it."

The man nodded at him, saying that he had heard him. They tried to ignore the screams and focus on the aurors before them.

"Who saw the deaths?" asked Moody.

"Greyback and Avery."

Harry paled at the names and strengthened his occlumency barriers, not wanting the memories of their crimes to overwhelm him.

"Harry?"

"I'm fine."

"Are you sure?"

"Yes." then the wizard raised his voice. "Auror Moody, if you don't mind I will talk with them."

"Not without me, boy."

Harry contained a wince at the word boy. Even after all those years, it still managed to make fear course through his veins.

He nodded curtly at his future professor and turned to the Doctor, but the man raised an eyebrow and he knew the Time Lord wouldn't let him enter the cell alone. He sighed again, listening to Moody giving orders.

"Johnson, Randall, the left side of the corridor. Cover it with the patronus charm. Greengrass, Rogers, the right side. You two, with me. Now."

They walked to the middle of the corridor while the others took place at the entrance.

"Which one first? Greyback or Avery?"

"Avery."

He had undoubtedly much less bad memories of Avery. Or memories at all.

Moody nodded briskly and walked to one of the cells. He opened the door and indicated for him to take out his wand before entering.

Harry did so and swallowed before taking a step forward. A hand holding his made him pause and look back. The Time Lord smiled softly and leaned down to give him a chaste kiss. Harry sighed in contentment and squeezed his hand in thanks for the comfort.

They walked into the room and saw Moody standing next to the door, his wand trained on a dark figure lying on a heap in a corner. Avery.

"Wake up, scum. We have questions for you."

The Doctor frowned at the rough treatment the prisoner was receiving, but said nothing.

"Scum, scum…" the man laughed insanely, shaking. "You aurors are scum. You will see it… you will see it… when my master returns…"

"When your master returns," sneered Moody. "do you really think he will worry about you? That you will be rewarded for your loyalty? You're as stupid as your fellow Death Eaters. The Dark Lord cares only for himself."

The Doctor felt better for not saying anything knowing the man was one of the followers of Riddle and had therefore contributed to his little one's pain. In his books, he deserved every horror Azkaban could ever give him. He wasn't going to say that aloud, though.

"But we're not here to talk about your master. Last week, when those dementors died, what did you see?"

"It's been a week?" cackled the prisoner looking up at them with craziness and gaunt face.

"Answer the question, Avery." growled the wizened auror.

"They died. The dementors died. Fell to the ground like puppets with their strings cut. Like inferi without magic."

"But how? How did they die?" asked the Doctor. "Did they do something before?"

"Who are you?"

"We're nobody." mumbled Harry taking a deep breath and a step forward. "Now answer the questions, Avery."

"Or would you rather we ask the dementors to come make you? I'm sure they'll be happy to spend some time with you."

The Death Eater whimpered at Mad-Eye's threat. It was obvious he was terrified of the dark beings.

"They died. They just died. They were fine and then they fell. I didn't see anything else. Not the dementors, not the dementors."

The man started to shake harder and harder, muttering unintelligible things. When the prisoner looked up at them with an insane glint in his eyes, the Doctor grabbed Harry's elbow and dragged him back.

Moody barely managed to put up a shield before the prisoner slammed against it.

"Back down! Back down now." ordered Moody harshly.

The Doctor did and pulled Harry back with himself. They stumbled out of the cell and Moody closed the door after all of them.

They were left panting in the corridor while the Death Eater clawed at the bars, trying to reach them. Harry pointed his wand at him and suddenly the shouts cut out, but they could still see his lips moving.

"Well, that was unhelpful." muttered grumpily Alastor.

"Are you okay?" asked the Doctor worriedly.

"Yeah, just… Greyback." said Harry abruptly. "Let's see if he has anything to say."

Moody looked into his eyes, searching for something and nodded.

"Do not get too close to him." warned.

"Why not?"

"He's a werewolf."

"A werewolf?" repeated the man looking at the teen with clear excitement in his eyes. "Like…"

"Like Remus Lupin. In fact, Fenrir Greyback was the one that transformed Remus." said softly Harry, obviously lost in his memories before shaking his head. "Well, let's go."

Moody opened another door and they entered the cell. They found a man dressed in rags and chained to the floor. He looked and felt feral and had the same wild energy Teddy had but much, much stronger.

"Greyback, we have a few questions for you."

"Moody. Coming to visit those you put here in the first place?"

"What did you see when those dementors died last week?"

"Why should I tell you anything?" growled.

"We don't have time for your games, Greyback. Answer the damn question." snarled the youngest wizard surprising the Time Lord.

The werewolf lifted his head and sniffed the air before looking at the teen with a strange look.

"Hello there, cub. You sure are a pretty thing. What are you doing in a place like this?"

The Doctor put an arm in front on Harry, gently moving him so he was hiding him a little with his own body.

"Oh, and what are you? His protector?" laughed Greyback.

"And anything he needs me to be." said the Time Lord coldly.

The werewolves laugh cut off abruptly and he regarded the man with calculating eyes, surprising for a man in Azkaban.

"I see." Then his eyes went back to Harry and his expression changed to a leer. "If what you want is to spend a good time, you can always come here and take these chains off me."

The Doctor felt the strong urge of punching the wolf, but it was Moody that pushed him against the wall.

"Don't make me force you to cooperate."

"Ask it nicely and I'll think about it."

But Harry didn't think he had the patience to be nice with the man that had cursed Remus and so many other children.

The wizard put the tip of his wand on the man's neck and crouched.

"I have another idea. You tell us what we want to know and we don't serve you to the dementors as their next meal. How does that sound?"

"You wouldn't do it, cub. We're family, after all. You wouldn't give Grandpa Fenrir to the big bad dementors, would you?" taunted him the werewolf.

"You don't understand the situation you're in, do you?"

"Lower your wand, cub."

"I'm not your cub."

"But you're the cub of one of my pups. I can smell it on you." stated the man. "I may not be able to put a name to his scent right now, I don't really remember all those that I turned, but you smell like the cub of one of my wolves."

"Be it as it may, we're not here for that. Answer the questions." ordered Moody.

Fenrir growled at the male before meeting Harry's unwavering gaze.

"As you wish, cub. We'll make a deal."

"We make no deals with Death Eaters." barked Moody.

"Then, you can get out."

"What do you want?" asked Harry.

"Take me out of Azkaban."

"You really think we'll accept that?" scoffed Harry.

"No, but it was worth a try." shrugged the wolf.

"Try again. And this time, try being more realistic." said the Doctor feeling like rolling his eyes.

"Fine. I'll talk if you tell me whose cub you are."

Harry contemplated the idea. Greyback would always remember his scent and that, coupled with knowing Remus' identity, could be very dangerous in the future. He didn't want to accidentally change the future.

However, there was time. He could always obliviate him at a later date or something. It was risky but it was the only option at the moment.

"Deal."

Moody grumbled, but didn't say anything.

"What do you want to know, cub?"

"What happened when those dementors died?"

"They were fine first, feeding on us as always. Then, something strange happened. One of them started flailing its arms around and scratching at his body, as if he was itching or something. Like a wolf with fleas." laughed the werewolf wildly. "The others scattered and, then… it simply fell."

The three free men frowned. That wasn't as helpful as they had hoped but it was better than with Avery.

"Anything else?"

"Not that I can remember. Well, there's the smell. Their under-scent. It disappeared."

"Disappeared?"

"Disappeared. Vanished."

"Thanks." nodded Harry getting up and indicating for the others to get out of the cell.

"Wait! Your part of the deal, cub!"

Without turning to look at the werewolf, Harry smiled.

"Oh, I'm sure you remember him just fine. Remus Lupin."

With that said, Harry stepped out of the cell and closed the door after himself. The Doctor saw with wide eyes as the werewolf took a few seconds to process the name before reacting, launching forward and against the chains, trying to get to Harry.

He heard shouts about rebellious wolf cubs before the sound cut off like with Avery and Harry turned to smirk at the wolf, winking as if he had just told him a very funny joke.

"Let's go meet with the others." muttered Mad-Eye.

As soon as they were out of sight of the werewolf, Harry deflated.

"Harry?"

Inside that cell, the wizard had been acting very out of character and he was worried it might have been from finding himself in this kind of situation in which he had to face Death Eaters that he probably knew from the future war.

"Sorry, Doctor. It's just… Greyback has done and will do such horrible things that…" the wizard sighed and pinched the bridge of his nose. "I couldn't show any weakness. He's a male alpha. Any sign of weakness and he wouldn't have answered our questions."

"It's okay. I understand, little one. Well, not really. I don't understand your world at all. Yet. But I trust you."

Harry stopped and looked him in the eyes before smiling weakly at him.

"I'll try to be worthy of that trust."

"Oh, you already are, little one."

"I'm not little." pouted, though he would forever deny it, the wizard.

"You are."

"No."

"Yes."

"I'm not little, Doctor."

"Of course you are. You are little. My little one."

The teen huffed and started to walk again after Moody, but the Doctor could still see the softening of his eyes.

"What did he mean with the under-scent comment?"

"Some creatures, such as werewolves, can smell a certain scent below the scent of a being. It's their magic. The different under-scents are the kind of magic the creature has." lectured Moody.

"For example, a dementor and a necromancer would have the same or very similar under-scent, since they both have mainly death magic. If the under-scent of dementor disappeared while it was dying, it means he died because he was drained of its magic."

"Then, a magical being dies if they somehow lose all their magic?"

"Well, not every being. Usually it's only those that are mainly made of magic, like the dementors."

"Oh! Interesting. So, what are we going to do now?" asked the Time Lord.

"We're going to meet up with the others and see what we can come up with." growled Moody.

"So there's not a plan?"

"No." said Harry sounding strangely happy at the thought.

"Don't sound too sad." teased the man.

"I work better without plans. Improvising is my thing." explained Harry blushing.

"What a coincidence. Mine too." grinned the Doctor.

Their grins slipped from their faces when they heard shouts coming from the group standing at the entrance of the maximum security area. Dementors. Dementors were swarming the place.

The aurors were being overwhelmed by the large group of dark creatures and some of them had already slipped past Randall and Johnson. Moody barked an order for Harry but the teen was already starting the spell.

He thought back on the kiss the Doctor and him had shared before meeting with Jack and Martha. The warmth of the Doctor's lips against his own, the scent that made him feel so safe, the simple bliss he felt just for being in his arms…

"Expecto patronus."

The Doctor saw as a bright white light got out from the tip of the wizards wands that he remembered seeing Harry try using against the Vashta Narada. Unlike that time, however, the lights took almost solid forms.

Moody's patronus looked like a ram or something similar while Harry's patronus… The Doctor felt his breath catch on his throat at the sight of the beautiful animal that came out of his wand.

It looked like a horse but it had the head and wings of a giant eagle and was covered in what he guessed to be feathers.

Now, the Doctor may not know much about Harry's world but he knew enough about mythology to know what it was. A hippogriff. It gave off waves of happiness and calmness.

Harry didn't waste a second before directing the creature to charge against the dementors that were still trying to slip past Johnson and Randall whilst Moody directed his against those that were approaching them.

Harry told the Doctor to move so he was standing against a wall instead of the middle of the corridor. The man did so and felt helpless as he saw the wizards battle the creatures.

His thoughts turned darker and darker, knowing he couldn't protect his Harry from these beings. He was useless… the Doctor looked around and saw the reason for his dark thoughts. A dementor had somehow slipped behind Harry's back.

As Harry was focused on two of the dementors that were attacking the barrier in front of Johnson, he failed to notice the dark shadow approaching his back.

"Harry!"

The Doctor's shout made him turn abruptly. A black putrid hand shot out of a dark cloak and wrapped around his wrist. Harry froze. The contact with the dementor only intensified the feelings of cold and horror they brought. The teen barely spared a thought to the dark mark appearing on his wrist where the dementor was touching him.

The being leaned in towards the young wizard while reaching up with his other hand to lower the hood. Suddenly, Harry couldn't see the dementor anymore. Something brown blocked his line of vision.

It took him a moment to realize it was the Doctor. The Time Lord had just put himself between a dementor and him.

The man was pointing his screwdriver at the dementor but it didn't look like whatever the Doctor was trying was working.

With horror clouding his mind, he thought he heard a whisper.

"Not… master…"

The wizard tugged on the Time Lord's trench coat and they stumbled back, trying to put distance between them and the creature.

A second later a patronus shaped as a swan charged against the dementor, sending it back to the others. Harry looked at Cassandra Greengrass in relief and nodded at her gratefully. The usually cold woman nodded back and gave a little smile.

Harry directed his patronus to continue charging against the dementors but more and more of them continued coming and slipping past them.

Some floated over to the cells and they saw in horror as some of the prisoners were Kissed.

"Back down! Back down!" barked Moody. "Everyone back to the storage rooms!"

The aurors and the two men huddled together, the patronuses trotting around them and keeping away the soul eating creatures.

A sudden thought struck Harry while he saw the dementors Kissing prisoners left and right.

"Moody! Black! Where is he?"

"What!?" grunted the old man.

"Black! Sirius Black! Where is he held!?"

"What does that matter right now?" growled the old auror.

"Just tell me!"

Seeing the old auror frown, Greengrass looked up at the ceiling in exasperation and answered.

"Next to Bellatrix Lestrange. Three cells down the corridor in front of Avery's cell."

Harry nodded and run. The Doctor's eyes widened and he run after him, ignoring the cursing of the aurors as the group split up.

Harry's patronus charged against any dementor that dared approach too much and the Doctor reached Harry as he was counting the cells.

"One, two, three. This is it." the wizard tried to open the door, but it didn't move. His wand pointed at the door. "Alohomora."

The door opened.

"Harry, what are you doing?"

But the wizard simply run into the cell. The Doctor followed.

The room smelled horribly. In a dark corner, they could see the form of a dirt covered man with his hands covering his ears to muffle the sounds of the other prisoners and rocking slightly.

"Sirius. Sirius, come on. We need to get out of here."

The form just rocked harder at Harry's desperate calls. His little wizard approached the man and took his hands in his.

"Sirius, please. You need to come with us."

Sirius, whom the Doctor was now fairly sure was Harry's in the future deceased godfather, looked up and gasped, clutching Harry's hands harder.

"James?"

The Doctor could practically feel Harry's pain and sadness rolling in waves off of him at that name.

"No, Sirius. I'm not James."

Sirius looked confused for a moment before he recognized the green colour that was so out of place in Azkaban and his eyes filled with tears.

"Ha-Harry? But you were only a baby… How long have I been here?"

"There's no time for that, Sirius. You must come with me."

The Doctor helped him get the other wizard on his feet and each grabbed an arm to carry him out of the cell. The young wizard smiled gratefully, a beautiful smile full of warmth, at the Doctor.

The animagus hadn't stopped looking at Harry for a second, drinking in his sight as if he was the most wonderful thing in the world. Not that the Doctor didn't agree on that.

"Harry, Harry, I'm so sorry… It's my fault. I didn't… I swear to you, I didn't want…"

"Shh, Sirius, I know. I know. It wasn't your fault."

Harry felt his patronus getting weaker as more and more dementors flocked to them, the combination of Sirius', Harry's and the Doctor's memories too tempting to be ignored.

Therefore, he was understandably relieved when the aurors patronuses joined his.

"What do you think you're doing?" growled Moody when he saw the prisoner the Doctor and Harry were carrying.

"You can shout at me later, Moody, now let's get the hell out of here. This is no place to discuss this."

The auror grunted and, keeping his crystal eye on a shaking as a leaf Black, directed them out. They run out of the area where the maximum security cells were and didn't stop until they couldn't feel the dementors anymore.

Sirius fell to his knees, exhausted. His health wasn't exactly the best and he had just had to run for Merlin knows how long.

When the patronuses vanished, Moody turned around to growl at Harry.

"Reckless child! What did you think you were doing!? Running alone as if we weren't surrounded by dementors!"

Harry held his head high. He wasn't going to apologize for saving his godfather. There was no guarantee he would have survived the dementors. Time could rewrite itself and where would that leave him? He wouldn't have met Sirius. He wouldn't have known he was innocent. Pettigrew would have still been considered a hero.

"Do you want to end up dead? Or worse, Kissed?"

He saw the Doctor's face pale at those words. They still didn't know if he was really immortal or just lucky and they had no intention to discover it anytime soon either.

Harry felt guilty. The Doctor would blame himself if he was killed. He didn't want to be the cause of the Doctor's suffering. And he knew the Doctor would suffer if he died. The man had put himself between a dementor and him! If there had been any doubt that the Time Lord loved him, it disappeared with that action.

"And, of course, you had to go and free…"

The sound of steps made them pause and they turned to see a disturbed looking Cray running towards them. He was alone.

"Cray! What are you doing here? Where are Thompshill and Stain?" asked auror Rogers worried for his men.

"They were Kissed."
