A/N: So, yes, I said I was writing a Whofic and here it is. A very interesting experience, because I have certainly never written an adventure sort of story like this before, and while I think it worked, you'll have to be the judge of that. Thanks to everyone who helped me get this finished, especially to Metonomia for being such a great Beta.

The whole fic has been completed, so I'll be posting a new chapter every couple of days. The story features a Future!Doctor; which one it is doesn't really matter. A lot of 10's personality managed to work his way into this Doctor, so you'll have to excuse me for that.

Anyhow, hope you enjoy. Allons-y!

It had been raining heavily all afternoon, a pounding rain that kept everyone indoors with no thoughts of venturing into the cold and wet. Wilfred Mott would normally have chosen an afternoon such as this to sit by the fire and reminisce, only it was little Melanie's birthday, so he and Silvia had bundled into the car and driven through nearly-deserted streets to Donna and Shaun's house.

Wilf's great-granddaughter was a bright, cheerful girl, and she had shrieked with laughter the moment he stepped through the door shaking his head like a wet dog.

"You shouldn't have come," Donna protested, "not in this rain." But she was smiling as he handed her his coat.

Silvia trailed Donna into the kitchen, leaving Wilf with Melanie as he untied his shoes. "'Allo, you," he told her, and she giggled and darted into the living room.

He set his shoes aside and was about to follow when there was a knock at the door.

That in itself was unusual – there was absolutely nothing wrong with the doorbell – but coupled with the sheeting rain, Wilf was just a little suspicious over anyone who might possibly be outside. Not only that, but he was fairly sure Donna had not invited anyone else to their little party. All the same, with a light shrug of his shoulders, he stepped over the damp spots on the mat and opened the door.

It was a girl who stood there, dressed in nothing but a t-shirt and jeans. Her blond hair was plastered to her head, and although she was completely soaked, the girl seemed quite unaffected by the cold.

"Hello," she said promptly in a breathless sort of voice, not at all minding Wilf's stare. "Would this be Donna Noble's house?"

"Temple-Noble," Wilf corrected, and moved aside automatically for the girl to step in. She did so, and heaved a brisk sigh of relief. "That is so much better. Terribly inconvenient, that rain. On the other hand, I'm sure the plants are enjoying it. Absolutely brilliant, rain is. Wouldn't you agree?"

Wilf found he didn't quite know what to say, so he just nodded. There was a pause, during which the girl beamed at him expectantly, and then asked hesitantly, "Is Donna here?"

"Oh, yes – yes, in the kitchen," Wilf answered, and then, coming to his senses, "Who should I say it is?"

"Jenny," the girl replied promptly. "I'm a friend from Donna's travels."

The stirrings of a warning sounded in the back of Wilf's mind, and he frowned uncertainly. "Egypt? Or-"

"Oh no!" the girl laughed. "I don't suppose she told you about the Doctor? Because I'm his daughter, you see, and they thought I was dead so they left, only I really wasn't – although for that matter, I thought I was dead as well, so I don't really blame them or anything, only it's terribly hard to find the Doctor after you've lost him, and I've been looking for absolutely ages, and-"

It was then that Wilf realized what she was saying. "You have to leave," he said fervently, and nodded out the open door at the street. "And never come again."

She blinked in surprise. "Sorry?"

"Donna can't remember, not ever. If she does, her mind will burn her up. The Doctor brought her back to us, told us she'd die if she ever remembered. You have to leave now before she sees you!"

Jenny's eyes grew wide as he spoke and she nodded slowly in miserable fear. "I'm sorry," she whispered, and stepped towards the door before turning back with hope in her eyes. "You – you don't know Martha, do you?"

Wilf was about to tell her that he had never heard of Martha before, but at that moment, a familiar and most unwanted voice came from the hall behind him. "Granddad, are you going to be standing by the door all day? We're almost ready for Melanie's birthday dinner and – oh, I'm sorry. Hello, I'm Donna. You are -?"

Wilf froze, but Jenny just smiled sadly and stepped out the door into the pouring rain. "Friend of the neighbours," she said quickly. "Got the wrong house in all the rain. I'm really sorry. So very, very sorry." Then, with one last tight smile, she turned and dashed off into the street.

"Well, I like that!" Donna huffed, coming to stand at Wilf's side. "A friend of the neighbours. She's running right to the end of the street! Some people – say, that reminds me of the time Karen..."

Wilf tuned out Donna's chatter as he watched the girl make her way to the street corner and pause. Alone, looking for her dad with no one to help her – he almost stepped out to call her back and offer what assistance he could, but then she was gone, swallowed up by the rain, and so he closed the door in one heavy movement.

On those rare occasions that the TARDIS did not follow the Doctor's coordinates, it almost always meant there was something important he needed to check out. Very often this would lead to a conflict of some sort, and more often than not, a great deal of running. So when the TARDIS decided to forego a trip to Hawaii in 1974 and travel to London, 2010 instead, the Doctor did the most sensible thing he could. He checked the soles of his running shoes and double-knotted the laces for good measure. Then he strolled outside.

It was a grey-ish sort of day, and judging by the damp marks on the pavement, it had been raining recently. This, being London, was not unusual, but all the same, the Doctor took note. Always better to take note of the unimportant things than to miss out on the really noteworthy details.

And there, right in front of him, her mouth hanging open in undeniable shock, was one such important detail. One very, very important detail. A Donna Noble important detail.

"That – that box. It just appeared out of nowhere," she gasped, and huffed a disbelieving laugh. "It – I'm sure I've seen it before. I've seen that box before. Appearing and disappearing. But – but boxes don't do that!"

Twice, the Doctor thought heavily as he walked slowly towards her. He kept his gaze steady, reassuring, even as Donna's eyes became more wild and fearful and confused.

"There was a man I used to know – a man with a box like that. I – he – how did I forget him? I'd forgotten him." She looked away from the distance and directly into his eyes. "I'd forgotten the Doctor. He – he made me forget him!" Tears began to leak down her cheeks. "Oh my – oh my -! What am I-? What-? What?"

"Donna," he said calmly, and lay a hand on her arm. Her expression was chilling – one of absolute horror and disbelief.

"I'd forgotten," she whispered. "I'd forgotten. Why did he make me forget? It isn't fair. It's not fair – fair – fair – fair – fair!" She broke off in a choked gasp and seemed to see him for the first time. "Who are you? What are you doing with the Doctor's TARDIS?"

Twice, rang the voice in his head, Only twice. "Donna," he said again, sadly. "Donna, it's me. I've changed – you understand about regeneration now."

"Oh," she breathed, and smiled feebly. "Yes, I understand. What I don't understand is why you, Mr. Time Lord, go to all the trouble of wiping my mind just to come back and make me remember again! Defeats the purpose, doesn't it? What do you say to that, space boy? Huh? Nothing? After doing that to my mind without permission. Mind-rape, that is. Mind-rape." For a moment the anger faded and he could see plainly the fear inside her. "I don't have much time now, do I?"

He knew what she was asking. Sucking in a deep breath, he shook his head.

"Only twice," she muttered, and wrinkled her nose at him in a way that made him ache for all those adventures the two of them had had together. "You couldn't have given me a few more, could you?"

"I'm sorry," he whispered.

"Ah, well," she sighed. "Are you all alone now? Tell me you've found someone else, after losing so many – oh!" Her jaw dropped and she stared at the Doctor in disbelief. "Jenny!"

"What?"

"Jenny! I –" A grimace crossed her face, and Donna shuddered violently. Twice, the Doctor thought. Only twice, and time is almost up.

Donna was gripping his arm. "Doctor, it's Jenny. I –I saw –" Another grimace. "She came to the house. She –" A yelp, and a gasp – Donna's hands flew to her head. "Alive. Jenny's a-" And then came the yell that seemed to drown out everything else and a wave of golden light blasted from Donna's head. The Doctor jumped forward as she crumpled, catching her the moment before she hit the ground. She hung limp in his arms, a pale shadow of all she had once been. If he closed his eyes, he could almost see her again, standing in defiance at his side, ready to fight against the world for what she knew was right. And now... In the moment before a tear could fall, he wrinkled his nose and took a deep breath to steady himself; then he laid Donna carefully down upon the pavement. With another deep breath he stood again, and after a whispered goodbye, he left her.

Only twice, he thought as he stepped into the TARDIS and wiped at his cheek. Only twice will her mind project outwards to protect her. The next time she remembers –

But there wouldn't be a next time, he decided firmly. Not ever. "Do you hear me?" he shouted at the TARDIS angrily, and she hummed back at him softly and with remorse.
