Bobby was still struggling over Rufus' death and even though they've found a case involving a series of unusual deaths among related people in Pennsylvania, he wasn't interested and had basically told them to fuck off. They've packed up Dean's Mustang and were worried about Bobby, but took comfort in the fact that Ellen would be home soon. There were no clues other than a thread of pure gold on the ground. After visiting one of the relative – Shawn Russo, all they learned was that the victims' ancestors arrived in America in 1912. Ellen told them that Jo had been working on the same case and that there have been 75 similar deaths nationwide, and the only common factor they found between the victims is that their forebears all arrived in 1912 on the Titanic, a passenger steamship that none of them had ever heard of. After further investigation, Sam found that on its maiden journey across the Atlantic, the Titanic nearly hit an iceberg. Disaster was averted, however, by the first mate - the suspiciously named I.P. Freely. He found a photo of the crew, and I.P. Freely turned out to be none other than Balthazar.

The brothers summoned Balthazar, who claimed that he went back in time to stop the Titanic from sinking because he hated the movie 'Titanic' and the song 'My Heart Will Go On'.

Sam asked confused, "Okay, I didn't think that was possible. I thought you couldn't change history."

"There are no more rules, boys." Balthazar replied.

Sam snorted as he stared at the angel disbelievingly. "Wow! So, you just, what, un-sunk a giant boat?"

Balthazar looked frustrated and exclaimed, "Oh, come on, I saved people. I thought you loved that kind of thing."

Sam crossed his arms and stated, "Yeah, but now those people and their kids and their kids' kids… They must have interacted with so many other people changed so much crap. You totally Butterfly Effect-ed history."

Dean who was staring silently until now said, "Dude, dude. Rule one: No Kutcher references."

Balthazar rolled his eyes and said, "Yes, unfortunately, there's still an Ashton Kutcher. And you still averted an apocalypse and there are still archangels. It's just small details that're different – like you don't drive an Impala." Sam and Dean exchanged a confused glance at which the angel continued, "Yes! Yes! What's an Impala? Trust me. It's not important. Well, apart from the fact that Voldemort's alive and is the ruler of the Wizarding Britain, there's nothing to be worried about."

Dean's head snapped towards the angel and he asked, "What?" At the same time Sam questioned bemused, "Wait! Do you mean he wasn't alive before you changed history?"

"He was as good as dead, so yes, and regrettably, the ancestor of the girl who defeated Voldemort, married someone else after the man she loved died on Titanic, but now that the ship didn't sink…" Balthazar shrugged offhandedly.

"She wasn't born." Sam completed quietly.

Dean snarled angrily, "How could you do this? The bastard and his minions have killed thousands of people across the world!"

Everyone knew about the Wizarding World. The supposedly Dark Lord, Voldemort and his Death Eaters had slaughtered half the population before talking over Europe. Apparently, he wanted to be the next Hitler, so he had announced to the whole world who he was and would kill everyone who would try to defy him. It had been a shock for the world to find out that there was a different world hidden from the normal people, who were now treated as third class citizens, especially in Europe with muggle-borns not far behind. Some of the wizards had fought against him, but were tortured and killed brutally, after which the remaining wizards had given him the reign. He wasn't exactly ruling over America and Asia, but he had an agreement with the ministers – 'they would accept him as their Lord and he wouldn't harm their citizens.'

"We didn't know this would happen and it doesn't fall in our jurisdiction anyway. They are Hecate's children. If she isn't worried, then why should we?" the angel defended himself before adding, "But all of this has nothing to do with you. And of course, see the plus side. Ellen and Jo are alive!"

That stopped the brothers short and Dean demanded, "Ellen and Jo what?"

Balthazar waved his hand in the air as they were supposed to know and said, "Uh… They're supposed to be dead." Sam and Dean shared a look, indicating how devastated they felt, but the angel continued, "You see? I save a boat, one thing leads to another, which leads to another thousand things and yada, yada, yada. To cut the long story short, they don't die in a massive explosion. So, lets agree that I did a good thing. I saved two of your closest friends." He smiled cockily at the boys.

Dean closed his eyes, but Sam said, "But now something is killing the descendants of the survivors."

"And?" Balthazar asked disinterested.

Sam shook his head and pointed-out, "And that's maybe like 50,000 people."

Balthazar raised an eyebrow and asked again, "And?"

Dean took a step towards him and said in a no-nonsense tone, "And we need to save as many as we can, but we need to know who's after em'."

"Sorry, you have me confused with the other angel – you know, the one in the dirty trench coat, who's in love with you. I… don't care." He told them with a smirk and disappeared.

With no other choice left, the boys call Bobby, who worked out that the Fates are responsible and apparently, they're trying to counter the changes Balthazar's actions bought about. Bobby suggested that they convince Balthazar to re-sink the Titanic, but when Dean revealed that Ellen and Jo would die, Bobby told them to do everything they can to not let that happen.

The next day, Sam and Dean try to speak to Shawn Russo, but he crushed under a bus right in front of them. That's when Sam noticed a woman watching from a nearby building and thinking that she could be Fate, they followed her inside. They were standing in a dark room, when she stopped time before opening all the gas valves in the kitchen. Dean's flashlight died when the time restarted and he took his lighter out. As soon as it sparked, the gas ignited, but Castiel appeared at the last second and transported the boys to safety.

"Are you aware what your frat bro did?" Dean demanded after Cas told them that they were somewhere in White Russia.

Cas didn't look at them as he said, "I'm aware. Balthazar can be impetuous."

Dean looked at Cas and asked, "Well, riddle me this – if fate's going after the boat people, why'd she try to waste me and Sam?"

Cas looked at him and answered indifferently, "Well, I imagine she harbours a certain degree of rage towards you."

"What did we do?" Sam questioned confused.

"Nothing of import – just the tiny matter of averting the Apocalypse and rendering her obsolete. And then there's the issue with the dark wizard."

"Voldemort? What's he got to do in all of this? Fate changed because the girl who was supposed to kill him wasn't born and fate's angry. I get it man, but why us?" Dean asked tiredly.

Castiel stayed quiet for some time shuffling from one foot to another and the brothers knew by now that it was a nervous habit. So, they stayed quiet, waiting for him to tell them. Finally, after a couple of minutes, he answered, "Dean, the girl who defeated or was supposed to defeat him was your daughter. Obviously, fate had a plan for the two of them and now even that's precluded because of Balthazar's actions. I think maybe she's a little irritated about that as well. Everything she had planned has been changed and you're the centre of it all."

The brothers stared at him wide-eyed after which Dean started laughing. Castiel looked at him as he couldn't understand what was there to laugh about; while Sam stared at the two with his jaw hanging open.

"Dean had a daughter?" Sam almost squeaked, when Dean had calmed down, seeing that Cas wasn't kidding.

"You're telling me that I have a daughter who defeated the darkest wizard of all time?" Dean asked incredulously, even though there was some anger hidden behind his words.

Cas nodded, "Yes. The Wizarding World was still at war, but Mary had already defeated him once because of which he was weak. But their world's existence was still hidden from rest of the world."

"Mary?" Sam quired softly.

"That was her name."

"If she's so important, then why isn't she born?" Sam asked anxiously.

"Mary's mother wasn't born because her ancestor married the man she loved, who originally died on Titanic. He was alive, so the woman didn't marry Mary's great-grandfather. And there's a boy who would be talking her place in the up-coming war." Cas informed.

Dean closed his eyes and sighed before asking weakly, "If she's my child, then she must be a kid. How did she defeat the bastard?"

"She was extremely powerful. If my assumption is correct, then she would've been the most powerful witch, if she survived the war." Cas told them casually, which was a wrong thing to say as Dean's fingers wrapped around the collar of his trench-coat and he asked dangerously, "What do you mean 'if'?"

"Dean!" Sam tried to stop his brother, but he knew it was of no use.

Cas stared at him unimpressed and said, "You've known about their world for a long time now and you know more than anyone else that coming out of a war isn't guaranteed." Before Dean could snap anything back, Cas continued, "This isn't of import right now. We need to stop fate before she kills you both as well."

With that Cas dropped the brothers back in Chester and vanished.

Sam and Dean woke up in the Impala back at Bobby's place, with Celine Dion's 'My Heart Will Go On' playing on the radio. Freaked out that they both had the same dream, Dean asked Sam, "Had a hate-on for Billy Zane? Why are you having my dreams, dude?"

"It wasn't a dream." They heard Castiel's voice and looked at him.

Dean was shocked at the revelation and asked, "Wait, what? You're saying that this actually happened? That t-the whole – Ellen, Joe, the thing with Mary not being born and Voldemort taking over the world – t-that was real?" he stammered with disbelief.

"Wait? So, what happened?" Sam asked curiously.

Cas looked straight at them and said, "Well I insisted he go back in time and correct what he'd done. It was the only way."

Dean turned around, looked at the tent in Bobby's yard and gulped. Then he nodded at Castiel and whispered gratefully, "I- Thanks, man."

Neither of them mentioned the 50,000 people who were killed on Titanic, knowing that it saved not only thousands of lives, but one thing that had become important to both the Winchesters. Not to mention, the world was a better place because she existed.

"Ellen and Joe?" Dean asked suddenly, at which Cas didn't answer and looked at him regretfully, but finally whispered, "I'm sorry."

Dean leaned back against the impala to hold himself before asking, "Hold on. So, if you guys went an-and changed everything back, then whole timeline or whatever. It just got erased?"

"Yes. More or less." Cas nodded.

He questioned bewildered, "Well, then, how come he and I remember it?"

Cas told him, "Because I wanted you to remember it."

"Why?" Sam asked confused.

"I wanted you to know who fate really is. She's cruel and capricious." Castiel replied truthfully.

"I'd go as far as 'bitch'." Dean muttered.

But Cas turned serious and informed, "Yes, and I also wanted you to remember how hard times are going to be. Voldemort is alive and her war has just begun."

Dean swallowed a bile rising in this throat; while Sam looked at his brother and then at his niece's tent sadly, knowing what the burden of the world could do to you and Mary was just a child.

Finally, Dean gathered himself and asked incredulously, "Wait. Did… Balthazar really… uh… unravel the sweater over a chick?"

"Yes. Absolutely. That's what he did." Neither brother noticed how Cas turned away from them while answering, how uncomfortable he was.

Inside, Bobby was asleep on the couch and the brothers look at him sadly, knowing what he'd lost. Dean covered him with a blanket and they let him sleep. They saw Padfoot sleeping on the carpet and went to the library, knowing where Mary would be. They were correct as Mary was reading one of Bobby's tomes. She looked up when she heard them, but wasn't expecting what happened next. In one fluid motion, Dean moved forward and hugged her, holding her tight against him. At first Mary stiffened. She had been here for almost more than month and knew that the three men weren't good at showing affection, especially her father who particularly hated 'chick flicks' as he called it. He hadn't hugged her until now and the tenderness by which he was holding her was almost foreign. No one apart from Sirius had hugged her like this. She pushed the thought aside and hugged him back tentatively.

What threw her off the loop was that as soon as Dean released her, she was engulfed in another pair of arms, which belonged to none other than Sam.

He released her and she looked at the brothers as they were staring at her with something akin to wonder and it was making her uncomfortable. Even padfoot was looking at them confused or as confused as a dog could look.

"Not that I'm complaining or anything, but, um… what was that for?" she managed to ask.

"Nothing. We're just glad you're here." Dean told her with a smile and Sam nodded his assent. She blushed under their scrutiny.

Mary looked at the sky before closing her eyes and whispered, "Cas? Castiel. I'm not sure if you're even able to hear this or not…" before she could finish, there was a flutter of wings and the angel himself was standing in front of her. She yelped and almost fell on her back, but steadied herself.

"Don't do that!" she gasped and closed her eyes to calm herself before opening them and looked straight at him. "I… uh, wanted to thank you for saving my life and healing my scars." She mumbled awkwardly under the intense gaze. "And I want to apologise for being impolite before."

Cas cocked his head to the side, staring at her and nodded. "There's nothing to apologise for. Sam and Dean are much worse."

She snorted at the irony of his statement.

"Sammy? Is that an owl on my baby?" Dean asked Sam, unable to believe what he was seeing. There was a snow-white owl perched on the Impala's hood looking straight at him with its bright yellow eyes, which seemed unnaturally intelligent.

Sam couldn't answer because he too was busy gawking at the beautiful bird. And before either of them could comprehend anything, there was a blur as Mary rushed passed them, knocking Dean out of the way in her hurry and squealed when her eyes landed on the bird, not noticing that he would've fallen on his ass if it hadn't been for Sam. Her squeal was so loud that the brothers winced and even Bobby came running out with a rifle in hand, only to be stopped short by the scene in front of him.

An owl was perched on Mary's hand, nuzzling its head under her chin; while the girl was almost crushing the poor bird with how tightly she was holding it. "Hedwig." She muttered to the bird lovingly.

"It's your bird?" Sam asked bewildered, meanwhile Dean rushed to his car to make sure the bird hadn't scratched it.

"Oh. I told her to follow me whenever she could before I left London." She told them distractedly, busy petting her owl.

"You're telling me that a bird followed you all the way to America just because you told her to? How is that even possible?" Sam questioned perplexed.

"Magic and Hedwig isn't just a bird, she's my first friend." She finally looked up from the bird, smiling and the brothers who smiled back instinctively; once more swallowing their anger at her guardians.

"No!"

"Oh, come on, please!"

"Not happening! Not even it's the end of the world!"

"But I'll miss all the fun! How many people get to go back in time for an adventure? I won't even interfere. I promise!"

Sam, Sirius, Bobby and Castiel were watching the father-daughter duo, who had been arguing from the past hour. Dean was adamant to keep his daughter as far away as possible from all the shit, while Mary wanted to go with him back to 1861. The four wisely stayed out of the quarrel, waiting for them to finish the 'discussion'.

"I could come along to take care of my girl." Sirius piped up at which Sam and Bobby sighed, while Dean snapped, "We aren't going on a trip to Disneyland!" With that, he left closing the door behind him with a loud bang.

For his part, Sirius did not pout and neither did Mary.

The brothers came downstairs and the four people stared at them wide-eyed. Sam was clearly frustrated, while Dean was having the time of his life.

"This is stupid." Sam muttered exasperatedly. "I look stupid." At which Sirius nodded and burst out laughing.

"You going to a hoedown?" Bobby asked bemused. Even Castiel stared at Dean incredulously, while Mary looked baffled and questioned, "Are you wearing a… blanket?"

"It's a serape." Dean told her proudly. "It's uh… Never mind. Let's just go." He looked at his daughter who was looking too smug for his liking, but ignored her in the favour of closing the duffel. "All right. Well… see ya at high noon tomorrow." He added while fixing his hat and Sam rolled his eyes.

They closed their eyes and the next thing they knew, they were in Sunrise, Wyoming. They both looked around in wonder when they heard a voice they knew well. "Wow! This is bloody amazing."

Both the Winchesters whirled around and their eyes widened when they landed on Mary. Dean was the first to recover from his shock as he hissed at her angrily, "What the hell are you doing here?"

"I told you I wanted to come." Mary replied like it should have been obviously.

"And Sirius agreed to this?" Dean asked knowing very well that the other man didn't trust them enough with Mary. There was no way he would have agreed to let her travel on a hunt, especially without him.

She shifted uncomfortably and muttered, "Well, we'll find out tomorrow, wont we?"

Dean closed his eyes and snarked, "Amazing. I can bet the man would be having a tantrum right now."

Sam who agreed with his brother wholeheartedly, knowing how dangerous the hunts could be, looked at her and said sternly, "Mary, we don't know how dangerous this could be. Especially in a place like this."

She pulled her wand out from her jeans, waving it in front of them and said, "Well, it's a good thing I bought my wand then, isn't it?"

Both brothers stared at her disapprovingly and she looked down at the ground. "I'll be going back to Hogwarts soon and I wanted to do something with my family. I wanted to know more about you and this is what you do. With Voldemort gaining power…. I don't know if I'll ever get another chance like this." She mumbled quietly without looking up.

Their hearts clenched painfully at the reminder. They hadn't forgotten the world where Mary wasn't born and Voldemort had wreaked havoc in the world. And they shuddered, knowing that this time she was his main target. Dean looked up only to see two pairs puppy-dog eyes staring back at him. This was much-much worse than Sammy's begging and he just knew that he couldn't say no to anything when they looked at him like that. Not that he would ever say it out-loud.

"Fine!" he sighed, which earned him a smile from Sammy and Mary literally jumped on him, hugging him with all her might and whispered impulsively, "Thank You. You're the best dad ever." She kissed his cheek and then hugged Sam before kissing him on the cheek as well, shocking both the brothers.

From the moment they've known her, they had known that she avoided any kind of physical affection, which they gathered could be from her time with her guardians. Sam looked at his brother, who was looking astonished and somewhat overwhelmed, and shook his head fondly. He nudged Dean bringing him out of his reverie, who almost blushed and cleared his throat unnecessarily.

"Alright. There are rules and you'll be following them. You stay with either Sam or me all times of the day till we get back home. You do what we say without any argument." He told her pointedly and she nodded. "You won't be using your magic until it's absolutely necessary. God knows what these people will do if they found out that there's a witch between them. And you better listen to us or you're grounded until you're 18, young lady." He told her sternly.

Mary just gaped at him, while Sam snorted. This wasn't even a fraction of how protective and possessive his brother could be. He had to suffer from it his whole life and it was about to increase, especially with Mary being Dean's daughter. Sam knew he wasn't much better when it came to his brother and now his niece, but he was much subdued.

Dean nodded, finally satisfied. "All right. Let's go find Samuel Colt."

Sam asked her curiously while setting a 24 hours timer on his watch. "How did you even convince Cas to let you come here without informing anyone of us? He always does what Dean says."

"I just asked him." She shrugged, at which Dean cursed the angle and Sam mumbled somewhat angrily, "Now I'm the least liked Winchester. Just great!"

Mary frowned, but laughed along with Dean when Sam almost fell in horse-shit. They walked into town and saw a judge reading a sentence of a man who was tied – apparently, Elias had killed his wife and was about to be hanged in the town square. Dean and Sam moved subtly in front of Mary to block her view, not wanting her to witness the gruesome scene. Once the man is put to death, the man watching the sentence turned around looking amused and said, "Nice blanket!"

Dean stared at the man offended, when two other men walked towards them, looking at Mary up and down salaciously before licking their lips and asked in a hoarse voice, "Must be nice traveling with a naked girl?"

Sam narrowed his eyes, while Dean growled at the man after which the two shuffled away before leaving. Mary was still looking around confused, searching for 'the naked girl' and both the brothers sighed at her cluelessness.

Dean removed his 'serape' hurriedly and donned it on Mary who squeaked indignantly. "My daughter isn't going to be naked in front of a whole town." He mumbled.

"I'm already wearing a sweater! I'm not gonna wear this hideous blanket!" she glared at Dean as she crossed her arms in front of her.

Dean snapped. "Tough luck! And it's a serape."

Meanwhile, Sam was busy being embarrassed as the men around were staring at them bemused. "Guys!" he hissed at the two bringing their attention back to the job. Once she was 'covered', she pouted the whole way to the prison and they left her right outside the door after another argument.

The three stopped short as soon as they entered the saloon and Mary looked around with shock. The room was filled with women and it didn't take her long to realize that they were hookers. Two men were drinking and the bartender was cleaning the bar. Every head turned towards them and Mary unconsciously shuffled behind her father and uncle, feeling more uncomfortable than she had in her entire life under their scrutiny.

"This is not awesome." Dean whispered to Sam horrified, who was looking equally awkward, but patted Dean on the back and walked towards the bar.

"What'll you have?" the bartender asked loudly.

"Uh… I'll have your top shelf whiskey."

The old man arched an eyebrow at Dean and said, "Only have the one shelf.

"That'll do just fine." Dean muttered and Sam shared a look with Mary. Yeah, he was just as eager as her to get out of here. He asked, "You Elkins?"

"One and only." The man mumbled as he poured a glass.

"You know a man named Samuel Colt?" Dean questioned.

"He passed through here four years ago." The man said with a nod.

Sam asked eagerly, "He still around?"

"Rumour is, he's building a railroad stop 20 miles out of town, just by the postal road. Middle of nowhere."

"The devil's gate?" Sam whispered to Dean and Mary frowned.

"Howdy, boys." They heard a voice and turned around to see a blonde woman descending down the stairs, wearing a low-cut dress so tight, that it left nothing to imagination. Her teeth were crooked yellow and it was clear to anyone with eyes that these girls were… less than healthy.

"Darla's my best girl." The man gloated which made the brothers uncomfortable.

"What do we have here?" Darla said as she raised a suggestive eyebrow at Mary while looking at her up and down. "You certainly look… sweet." She told Mary as she patted her on the cheek and Mary winced.

Dean's eyes narrowed and he swiftly moved in front of her, pushing Mary between him and Sam, who held her shoulder and pulled her closer to him.

Darla's smile widened as soon as her eyes landed on Dean and she whispered, "Try me." Who backed away her with a grimace, and looked ready to run. "You want a kiss?" she muttered seductively as she leaned closer to him, much to Sam's amusement and Mary's disgust.

Mary knew she didn't know the circumstances of the lady and it was her job – a way to earn money for livelihood and she understood that, but just imagining her father like this was plain nauseous.

"S-so much more germier than I pictured." Dean mumbled as he leaned father back and Sam laughed silently sipping his drink.

Dean sagged with relief when the judge showed up and took Darla upstairs. He picked up his glass of whiskey before taking a sip and spat it all on Sam with a cough, who glared back at him furiously. It was just moments later, that they hear Darla's scream and rushed upstairs, but not before ordering Mary to 'stay exactly where she was'. It was much safer and they knew that she could apparate if needed. They found the judge dead, burned to ashes and Darla swore that it was Elias' ghost that killed him.

That night, they discussed the possibility of the Phoenix being the man, Elias, who wanted revenge on the three men that killed him: the judge, the sheriff, and the sheriff's deputy. Finally, they decide to split up. Dean would be staying behind to join the sheriff's posse and hunt down Elias, while Sam would be going to find Samuel Colt. Before Sam left, Mary placed a tracking charm on him, just in case.

The next morning, Dean and Mary went to the saloon, ready to form up a posse and go after Elias, only to find the burned body of the sheriff.

"Who's the sheriff now?" Dean asked the bartender as they looked at the ashes on the ground.

The bartender picks the star from the sheriff's body and pins it on Dean and said, "Congratulations, sheriff."

Dean looked at Mary with panic etched on his face, who held both her thumbs up at him and grinned, much to his chagrin.

After they stopped the sheriff's deputy from escaping Elias' ghost', Dean practically told him that he needed to play his part as bait and locked him up behind the iron bars. It wasn't long before Elias showed up, demanding Dean to open the cell, who refused and found out that the phoenix was vulnerable to iron, which was why he couldn't escape his iron shackles before he was hung.

On realizing that Dean was a hunter, Elias told him that although a phoenix, he had been married to a human woman that he loved. On a visit to town, she was assaulted by the deputy and when Elias came across them, the deputy shot both of them and his wife died in his arms. And because Elias was unable to die, the judge, sheriff and the deputy pinned his wife's murder on him and tried to put him to death. Dean was moved by his story, but was still resolved to kill him and even though Mary felt sorrow for the man, but she knew what they were here for. If they didn't get the ashes, then the world will suffer. So, she pulled out her wand and clenched it tightly in her hand, having a hunch that this wasn't about to be easy.

Elias looked at her with a frown, but then turned back towards Dean and before they could comprehend anything, he grabbed a gun from a nearby holster and shot the deputy through bars, who died instantly.

"Wow. I should've seen that coming." Dean uttered nonplussed before he whispered to Mary, "Run!" Ready to bolt himself, when Elias' turned and fired. This time she was prepared for the attack and conjured a shield in front of them. Dean saw as the bullet collided with an invisible barrier in front of them and fell to the floor. His eyes widened along with Elias' and snapped towards Mary, who was holding her wand, pointing it straight at the phoenix. He narrowed his eyes at her and fired thrice, only for the bullets to collide with something mid-air before falling on the ground.

"Amazing." Dean whispered with awe; while Elias' glared at Mary before running out of the door. Dean followed him with Mary not far behind. They both saw Sam and sighed when he gave the Colt to Dean, who walked into the town square and called, "Get out here, Finch."

Both Mary and Sam frowned. "What're you doing?!" Sam asked.

Elias' came out and stopping a couple of feet away from Dean, ready for a duel. Mary saw the time and her eyes widened and she pointed the time to Sam, just when both men drew their weapons out and shot. Elias missed, but Dean hit him square in the chest with the Colt, killing him. They saw the phoenix turning into ashes right in front of them.

"Dean! The ashes." Sam called and pointed towards clock. It rang indicating the 24-hour mark and both the brothers rushed forward to gather the ashes, while Mary waved her wand muttering a spell, hoping that it would work when suddenly, they were pulled back and were back in Bobby's house.

The three looked around, seeing Castiel, Sirius and Bobby in front of them. Sam and Dean stared at the empty bottle, stunned before closing their eyes with a frustrated groan; while Castiel sighed tiredly.

Sirius, who didn't care about anything other than his goddaughter slumped with relief when he saw her in one piece and unharmed before stating strictly, "Mary Potter! You're in serious trouble."

Mary gave him a sheepish smile and he melted just like that.

Dean although had other issues. "You gotta send us back." He told Cas, panicked, who was sitting on a chair with a grim looking Bobby.

Sam looked at his brother and said, "Dean, look at him. He's fried."

Mary looked at everyone confused and asked, "Why is everyone so gloomy? It was bloody brilliant."

Four heads snapped towards her annoyed, before Cas uttered vexed, "I never want to do that again."

When they ignored her, Mary finally said irritated, "But why do you have to send us back? You killed the phoenix and we have the ashes."

Once again, every head turned towards her with the similar expression of bafflement on their faces, until Dean finally chocked out, "What?"

She pulled a small pouch from her sweater, dangling it in front of them and they stared at it, before Sam rushed forward and opened it, pulling out a glass bottle full of ashes.

"That's…" Bobby started.

"Ashes of a phoenix." Dean said with wonder, before looking up at Mary and asked, "How…?"

She waved her wand in front of him and said smugly, "You would've been doomed without me."

Dean couldn't stop the laugh that bubbled out of him before hugging her and Sam joined his family.

Mary couldn't believe that the vacation was almost over. For the first time in her life, she wasn't eager to go back to Hogwarts. In last two months, Dean, Sam and Bobby had somehow become the family she had always wanted. Even Cas to some extent, no matter how different he was. She had to leave in about a week, so the brothers had decided that they would hunt after that as it would be much safer for her. Another thing was Sirius. When she had told him to stay here instead of going back to London, he had categorically refused her, saying that she needed someone with her. It took everything she had to break his resolve and literally forced him to stay here because there was no way he would be able to enter Hogwarts or anywhere near the Wizarding World for that matter without being killed.

But somehow, he had convinced even Dean and Sam that she shouldn't be going back alone, as Voldemort was back and she was his main target. After which she had a huge fight with her father, who wanted to 'kill the son of a bitch'. Castiel had to explain to him that he had his orders and won't be able to help them in anyway. She had told them that as long as they had Dumbledore, Voldemort wouldn't attack them.

Dean had finally agreed to let her go but only if he get to meet her friends because he didn't trust Dumbledore one bit and Sam agreed with his brother as usual.

"HAPPY BIRTHDAY….!"

Mary looked around with wonder and blinked. It was July 31st, her birthday which had never meant much to her until now. She had spent all her birthdays at the Dursley's who probably didn't even know when she was born, but here she was with the people which had been practically strangers until recently. She couldn't believe what she was looking at. That how much they did for her.

Bobby's living room was filled with balloons. There was a chocolate cake on the centre table along with numerous gifts lying on the carpet.

"You did this all for me?" Even though she knew but she still asked looking at everyone.

"Who else we're gonna do this for?" Dean grinned at her and added excitedly, "Come on. Hurry up. Tell me how the cake is?!"

She looked at the cake and frowned. There was something different about it and as she looked closer, she realized that it was a homemade cake. She looked up and asked bewildered, "You made this?"

"I did." Dean nodded proudly, at which Sam glared at him; while Castiel frowned. "I thought Sam made it."

"Well, I found the recipe and I bought the ingredients. Sam just mixed them together." He told her with a pout.

She cut the cake and knew it was the best thing she had ever tasted. Sirius and Dean had a fight over the cake, which stopped when Bobby threatened to throw them out.

She found that some of the gifts were from her friends, but she kept them for later. Sirius gave her a two-way mirror, through which she would be able to talk to him anytime she wanted, which had been his family heirloom. Bobby gave her a couple of books on spells and curses which he thought would help her in the war. Sam surprised her the most. He went to America's magical district with the help of Cas and bought a pendant which had been spelled to inform them if she was in trouble, as long as she had it on her. He also charmed it himself, so the demons wouldn't be able to possess her. Dean, who had been waiting eagerly gave her a scrapbook with he made with Sammy's help. It had all the pictures they took in the past 2 months. It was filled with silly pictures and a couple of them even had Cas in them. He also gave her a gun which Cas used his mojo on to hide from everyone, but her with strict instructions to keep it with her always. At last, he gave her a bracelet which belonged to Mary Winchester, her grandmother.

Mary had never been more grateful for anything in all her life. She was so overwhelmed by their love, that she almost cried before launching herself at Dean. "Thank you." She whispered when he hugged her back, feeling the same wave of affection for her which had always been reserved only for Sammy.

She hugged Sam, Bobby and Sirius as well, not having enough words to express her emotions.

She kept all the stuff in her trunk as soon as she returned to her room. She was about to go to bed, when Cas appeared in front of her and she gasped with surprise. "How many times have I told you not to do that?!"

He didn't reply like he normally would've, instead shuffled awkwardly on his feet. Mary frowned at him and prompted, "Cas?"

He blinked and said seriously, "The angels are rebelling and most of them hate the Winchesters. No one knows about your existence until now. They wouldn't stop at anything if they found out that Mary Potter is the daughter of Dean Winchester. Would you let me hide you by carving some sigils inside you? It would make sure that you're protected from all the angels."

Mary gulped. "Inside me?" was the only thing she was able to ask.

Cas nodded. "The Enochian sigils will protect you from all the angels who wish you any harm."

She thought about it before asking, "Does my da… uh, Dean and uncle Sam have these as well?"

"The angels are well aware of their existence. They have my protection, but hiding them would be of no use." Cas answered truthfully.

She took a calming breath and nodded. He shifted closer to her before placing two fingers on her forehead, her eyes rolled at the back of her head and she fell unconscious. Cas caught her just in time and laid her on the bed. "I'm sorry. It would be less painful like this." He muttered as he pressed one finger to her sternum. Her features contorted with pain even in her sleep and he apologised once again. He stayed at the corner of her room until he knew that the pain has passed, leaving her to a peaceful slumber.

It was only 3 days later, when they noticed that something wasn't right. Dean, Sam and Bobby were discussing the strategy about how to find 'The Mother' in the yard, when suddenly the wind picked up speed and the three tensed. They pulled their guns out, thinking that it might be a demon, but were confused when they saw black smoke gliding towards them from the air, only to stop right in front of them. Two men appeared from the smoke, wearing long black cloaks. They were both thin, had dark hair and were looking around with a blank stare, but the distaste was clear in their eyes.

"Who are you?" Sam asked, gun aimed towards the men, who merely snorted at them as they eyed their weapons before one of them said, "We'll let you live if you tell us Potter's whereabouts."

The three men tensed even more as they realized that these men were Death Eaters and were here for Mary.

"I'll tell you what? Why don't you go fuck yourselves?" With that, Dean fired, but one wave of his wand and the bullets stopped mid-air and vanished.

"Such fools, muggles!" the man whispered wistfully before waving his wand again, their guns flew away from them and the man smirked.

Before any of them could think, the man muttered something and a jet of red light flew towards them. Dean hurriedly shielded Sam with his body, while Bobby ducked down. When nothing happened after a couple of seconds, they opened their eyes and saw the man staring behind them with a cruel glint in his eyes. They turned only to see Mary, who moved forward until was standing in front of the three, keeping her wand at the Death Eaters.

"Potter! You kept us waiting. You weren't easy to find, so we asked your aunt, but apparently, she didn't know where you were. Neither did your uncle and cousin. They send their regards." He said with a smirk.

Mary's hand waivered as she demanded, "What did you do?"

He pretended to think, then shrugged. "Well, your cousin is alive. Sort of."

"You stay away from my goddaughter." Their eyes snapped towards the voice, only to see Sirius standing beside them, wand in hand, staring furiously at the two men.

"Dear cousin. You're still alive! Pity! We'll have to remedy it now, wont we?" Rodolphus said through clenched teeth, eyes filled with hatred and shouted, "Avada —"

But Mary didn't wait and yelled, "STUPEFY!" and sent him flying backwards.

The Winchester's and Bobby watched the fight with no way to help without their guns. Dean and Sam had never felt more helpless, but were amazed when they saw Mary and Sirius were in no way less than the Death Eaters. They tried to go to the Impala which held most of their weapons and was just a few meters away, but a purple light hit the shed above and it crashed on them. Thankfully, the shed wasn't heavy and they only had some minor injuries. Dean tried to call Cas, but to no avail. They turned back towards the fight wands were flashing like swords, sparks flying from their wand tips, ducking and jumping in a way which reminded them of their worst hunts. They could see that Mary had a few cuts, but otherwise she was fine, unlike her opponent who was bleeding from a deep gash.

The Death Eater fighting with Sirius glared at him and with a scream made a sudden slashing movement in the air with his wand from which flew a streak of yellow flame. It passed right across Sirius's chest and he looked down with surprise. His eyes found Mary before crumpling onto the floor where he lay motionless.

Mary's eyes snapped towards him and widened. "SIRIUS!" Which was the wrong thing to do as a jet of red light hit her and she collapsed on the ground. Even though she was familiar with the pain, she still couldn't stop herself from screaming.

Dean stared horrified as Mary's back arched from the ground as she screamed with agony, he ran towards her and shouted at the man, "STOP!"; while Sam darted towards the Impala as subtly as he could.

The Death Eater limped towards the other one, who wasn't torturing Mary any longer, but was smiling crudely at Dean. He then looked down at Mary and said snidely, "Bella would love to play with you before we give you to the Dark Lord. But let's take care of your muggles."

Mary hadn't even gained her breath back from the curse when Rabastan shouted, "AVADA KEDAVRA!"

"No…" She whispered horror-struck as she watched the green light rushed towards her father, but before it could hit Dean, a truck flew in front of him. The spell collided with the truck which blasted and was flung to the side before it could hurt anyone.

"What – ?" Rabastan said, staring around and uttered with alarm, "Dumbledore."

Mary turned around, her heart pounding. Dumbledore was standing on the side, who turned and was gone in a whirling of his cloak; next second, he reappeared between Dean and the Lestrange brothers, looking both disappointed and angry. The next thing they knew, they heard gunshots and everyone's head snapped towards Sam, who had shot Rabastan. Dean and Bobby had been shocked until now, looked oddly proud of Sam. Dumbledore himself looked shocked before composing himself and turned back towards Rodolphus, who stared at his brother as he died with seconds. His furious gaze met Sam's and he hissed, "You worthless swine!"

Not giving a chance for anyone to reply, instead bringing his attention to himself, Dumbledore said calmly, "We both know that you do not stand a chance, Rodolphus. You shouldn't have come."

"You were always a fool! The Dark Lord is going to kill you soon and then there will be no one to save your precious Potter." He spat manically and suddenly fired the killing curse. A car galloped in front of Dumbledore that took the blast and shattered with a blast. And before Rodolphus could fire another curse, Dumbledore waved his wand as though brandishing a whip. A long thin flame flew from the tip, wrapping itself around the other man tightly and immobilising him. Then he went towards the Death Eater, staring at him for a long time, after which he waved his wand and the man fainted.

Everything was eerily silent for a moment, before Dumbledore turned towards the Winchesters and stated, "It would be a good time to hide Mr. Black. The aurors will be here soon."

This seem to bring the Winchesters out of their shocked state and they noticed that Mary was already beside Sirius, trying to revive him. Dean hurried towards her and Sirius, while Sam helped Bobby, who seemed to have a broken his leg. Dean tried to console a frantic Mary, as Dumbledore transformed Sirius into his animagus form and helped him inside. It wouldn't be good if someone saw Sirius here under the current circumstances.

They heard cracks of appration and saw many men appearing outside. The head auror talked to Dumbledore and after making sure that the people here were squibs, left with a tied Rodolphus and the body of Rabastan. Mary rushed to Sirius's side and waited for Madam Pomfrey, who appeared and rushed inside hastily after talking to Dumbledore. She gave Sirius some potions, telling Mary that the man would be fine after a couple of days of rest. The curse which was used on him was turning his blood into poison and he would've died without the cure, which thankfully she had. 'Thanks to Severus'. Then she healed the minor injuries of the Winchesters and gave Bobby a bottle of skele-gro and a pain potion, which he took after being scolded by the medi-witch, scaring the man.

Once everything was done, Madam Pomfrey had left leaving potions for Sirius and a calming draught for Mary; meanwhile Sam and Dean had kept an eye on everyone, agitated and restless.

Bobby and Sirius were sleeping, while the three Winchesters were sitting with Dumbledore in the living-room. Now that they had the chance, the brothers gawked at the man in front of them. He was just as tall as Dean and very-very old, unlike a man who had kicked someone's ass in just a couple of minutes or was it seconds? His silver hair and beard were both long enough to tuck into his belt. He was wearing long robes which were bright red with a purple cloak that swept the ground, and high-heeled, buckled boots. His blue eyes were light, bright, and sparkling behind half-moon spectacles and had a crooked nose, as though it had been broken at least twice.

Mary looked at Dumbledore and asked, "Professor? How did you know where I was?"

Dean was tense beside her, ready to shoot at a moment's notice, while Sam was staring at the man curiously.

Dumbledore's eyes twinkled as he looked at her and said cheerily, "What matters the most is that you and your family is safe. I'd say I arrived at the correct time."

Mary's eyes filled with hurt as she stood up, startling both Dean and Sam, and shouted, "You knew? You knew and even then, you sent me to the Dursleys'?"

The old man just looked at her through his glasses and said, "No one other than Sirius knew about your secret, Mary. You haven't been in London from the past 2 months. Do you think I'd leave you unprotected?"

Mary's eyes went to the ground ashamed, while the brothers stared at her headmaster – apparently 'the most powerful wizard in the world and the only one that Voldemort feared', according to Mary. He stared at the brothers with eyes that seemed brilliant and looked like they were piercing your soul. He had an almost unearthly calm and relaxed demeanour and had an aura of serenity and composure.

"You don't need to worry about Lestrange or any other Death Eater finding you here. They were confident that you would be alone and, in their desire, to impress Tom, they didn't mention it to anyone. I don't think he'll even remember it anymore." He told her mischievously.

Sam and Dean looked at him confused, but Mary gaped. "You obliviated him?"

"Did I?" he winked at her and the brothers blinked. He stood up suddenly, looking at the objects around them curiously and said, "I strengthened the wards of this place, so no one would be able to find it, apart from the ones who are invited."

She nodded gratefully, but asked, "Professor? How did they know where I was?"

He looked at her from under his glasses and answered gravely, "You were protected by your mother's blood at your aunt's house, which was why you were placed with them. Once you left it, it wasn't difficult for them to track your magical signature. Which is one of the reasons I'm here. Now that you've two blood relatives, the wards for your protection can be strengthened."

"And those sons of bitches won't be able to find her if we do that?" Dean spoke for the first time.

Dumbledore stared at Dean before adding pointedly, "No one is aware about her family. As long as we keep it that way, she'll be protected here."

She looked at him and mumbled, "Hermione and Ron." Dumbledore smiled at her before searching something in his pockets and pulled something out. He offered it to the three and asked brightly, "Chocolate frogs?"

Mary took one, but the brothers gaped at the man. The brothers took one each, focused on how the most powerful wizard of the world ate the chocolate excitedly.

Sam blinked and then asked slowly, "Was it me or did the chocolate… jumped out of the package?"

"It's a frog. It's to be expected, isn't it?" Dumbledore supplied as he finished his chocolate.

Dean eyed the man and couldn't stop himself from asking, "I'm sorry, but how old are you exactly?"

"Dean!" Sam hissed, Mary spluttered, while the man merely smiled. "I'm certainly not as old as some people you might've met."

Dean leaned closer to Mary and whispered not so quietly, "Is he — crazy?" Mary turned red with embarrassment, while Sam sighed before giving the wizard an apologetic glance, who waved him off.

"I assume you would want to stay here for a day or two before returning to Hogwarts?" he asked Mary with a knowing look, but before she could open her mouth, Dean stood up and questioned, "Now wait just a minute! How do we know she's safe with you? Most of the things that had happened to her were inside that school of yours?"

Mary's eyes widened, but Dean silenced her with a glare and she grumbled something under her breath unintelligently.

"I feel I owe you an apology, my boy." Dumbledore said to Dean hesitantly, who bristled at being called 'a boy'. "There is a war brewing and I haven't been able to shield her despite my best attempts. But there is one thing I can assure you of – I won't let any harm come to her as long as I'm alive."

Dean looked at the man, seeing the sincere look on his face and nodded, because if anything happened to his daughter, there would be no place on Earth he would be able to hide. He would find and kill the man himself, no matter how powerful the wizard was!

"Professor?" Mary called and croaked out, "Rodolphus said… t-the Dursley's?"

He looked at her sadly and said, "The aurors found your cousin alive, but… the healers are looking after him." He patted her hand for comfort before disappearing.

EN: There is nothing romantic between Mary and Castiel at the moment. It will come in the sequel. It would be 2-3 years from this timeline (probably Season 9 or 10), so Cas will be more human and will understand his feelings better. Right now, he likes her and wants to protect her just like he would do with the brothers.

The two episodes that I've used here are from season 6, which will give us time for Cas to become humanish… until they get together.

It's my birthday and I wanted to post this today anyhow. Not sure when the next update will be, but I'm hoping to finish it soon. Also, I wanted to apologise for not replying. I joined a new firm and it's keeping me busy.

Have a nice day everyone. 😉
