Hey guys! I'm back. I had this idea and just had to write it down. This is the first chapter, and I'll post one more in a few days. Let me know what you think. I loved writing it

I don't own Doctor Who

"Did I ever tell you about Donna Noble?" The Doctor asked his wife. She had her head in his lap and rolled her eyes. As if he needed to tell her. She was famous throughout the universe. She thought that maybe he just liked to brag about the famous people he'd met and saved. Like William Shakespeare. "Did I ever tell you about how Shakespeare was in love with my companion Martha?" Or Agatha Cristie. "Oh yeah, I saved Agatha Cristie from a giant alien bee" At least she could shut him up about Cleopatra...

"The timelord-human metacrisis girl?"

"She was much more than that. The most important woman in the universe" At that, River made a snort of discontent. He laughed and took her hand before she could pull away

"But not the most important to me" River smiled, and resettled in her spot on his lap.

"What about her?"

"She traveled with me for a year or two. We went everywhere, but she never realized how important she really was. The first one in a long while not to fall for me" He was clearly bragging, so River laughed.

"I suppose the bowtie was a huge turn on"

"Well it was in previous forms. But you'd know all about that" He placed her gently beside him and stood up "I've been meaning to give you this for a while..." She followed him over to a cupboard. He opened it and pulled out a small bundle. He turned around and handed it to her. She opened it, and a few pictures spilled out. She bent down and picked them up. There were eleven pictures of men, some young, some old. One who was very familiar on top.

"Are these all you?" He nodded. "Even the one wearing celery?"

"An unfortunate fashion choice"

"So which one was the lady's man?" He looked slightly affronted

"Who said it wasn't all of them?" She gave him a look.

"Well I was well loved all my life!" She snorted in disbelief and looked down at the pictures in her hands and pulled one out.

"It was this one, wasn't it?" He looked at it. It was his previous face, his tenth. He nodded. She kissed him on the cheek and whispered "Knew it" into his ear, before leaning back on the chair. He sat down in it and patted on his lap for her to sit back down. She did, and he decided it was time to launch back into his story.

"So back to topic, she was brilliant. She stopped me from doing a lot of things I would have regretted, and made me do a lot of things I'm proud of. She somehow understood how I felt when... when things went wrong" He tried to cover up a few tears and River looked up at him.

"Is something wrong? You- you don't need to keep going"

"No, I'm fine."

"Okay" she said reluctantly, biting her lip a bit nervously. "So how did she manage to become part-timelord?"

"We were in a bad place. I was trapped by Davros, along with Rose" River rolled her eyes in annoyance, and the Doctor laughed. "No need to be jealous. So then he threw the TARDIS into the heart of the empire. It was going to burn up, and Donna was inside" River gasped, and the TARDIS shuddered a bit, like it remembered. "I saw it in the fire, and then the stream cut off. I assumed that they were gone"

"But how did she survive?" River asked, slightly protective over it, rubbing her hand on the wall lightly

"All in good time. So then Martha and Jack and Sarah Jane and Rose's mother and ex-boyfriend all got caught too. Davros revealed his plan. A reality bomb. Tear apart all of reality outside the Dalek empire" She gasped again. She knew that it had been stopped, but hadn't realized just how bad things had gotten for him.

"And you stopped him?"

"No"

"No?"

"Donna did"

"Are you going to tell me how she survived then?" He laughed at her eagerness.

"My hand saved her"

"Your hand?" She looked at him in disbelief. She waved the picture of his tenth self in his face. "Definitely two hands in this picture."

"Oh come on, you know this one! You've done it too" She thought of herself when she was a little bit younger, the last time she had regenerated- the last time she ever would.

"You somehow lost it right after regeneration." She said solemnly, dropping her head down a little bit He put a finger under her chin and pulled her head up, somehow knowing what she was thinking about.

"You are forgiven. You saved me"

"I also killed you…"

"Because you were kidnapped at birth by a mad woman because I couldn't save you. I don't really want to argue about this again. Do you want to hear what happened next?" She nodded, still looking a bit like a beaten dog.

"Before we were captured, a Dalek had shot me. I was going to regenerate. But I wasn't ready to go yet, and so I shot my spare hand full of regenerative energy, only using enough to heal myself" River shot up, excited.

"So Donna was in the TARDIS with your regenerative energy-high hand? And then… she touched it, and something transferred, giving her the memories of yours contained in the energy!"

"Almost perfect. Just missing one aspect"

"What else?"

"What happened to the hand?"

"It… I don't know" her excitement faded slightly

"Well I'll give you a hint. I have a twin" That bit of information entered her brain in a burst of fire, making the ideas spread until she came to it.

"It was two sided! She got a timelord's brain, and your hand got a human body! Oh, that's amazing!"

"Exactly! Except the information didn't come to her immediately. It was still buried in her head"

"So your clone got the TARDIS out of there! And then they appeared and popped out of the TARDIS. I bet Davros had a fit" the Doctor laughed.

"A bit of one, yeah. But he got over it quickly and trapped John" River's quizzical look, he explained. "John is what we called my clone. He was human, so he got my human name. John Smith"

"Okay… So everyone but Donna's trapped, but she's still just human… Let's say she tries to attack Davros, and he somehow stops her too… but he underestimates her and leaves her on the ground to taunt you. She gets up, somehow has your brain in her head, and stops him" she finished triumphantly, happy with her idea. The Doctor stared at her wide-eyed "I'm guessing I was close"

"She tried to use a weapon against him, but didn't know how. He shot her with electricity, giving her the jump start she needed to access my head. She got to the Dalek console and messed with them. Shorted out Davros's electricity, released everyone… made the Daleks into ballerinas" River laughed, imagining it in her head. She thought she'd like this girl.

"So the Daleks are stopped and everyone's safe… why did she leave then?" His eyes turned down, and he sighed. He seemed absorbed in the memory. They sat in silence for a few minutes. She was just about to get up when he finally spoke.

"Because it's not possible. There can't be a human with a timelord in her head"

"What about me?"

"You're special. You were born part timelord, still only one mind in your head. But Donna had two. Her own, and mine. And it was too much for her. I had to take away her memories. I couldn't take my brain out, but I could bury it. Deep enough that she'd be safe, unless she remembered"

"But your clone was a human with a timelord brain. What happened to him?"

"He was like you. Part human, part timelord. But still only one brain. I dropped him off with Rose. They could grow old together, something I couldn't offer her. I dropped everyone else off, explained to Donna's mother and grandfather"

"How did they take it?"

"Not well. But there was nothing anyone could do. If she remembered, she'd burn up…"

"I wish I had met her" River said softly before standing up. "I'm going to bed"

He watched her walk out sadly

"You did" He whispered, quiet enough that she couldn't hear him.
