Hello! Welcome to Alons-y! I love love LOVED writing this book, so much that I've come back to it two years after I originally finished to add in some more chapters! Don't be afraid by the insane amount of chapters. Most of them are pretty short and it flies by fast! You probably won't be able to finish it in one sitting, so make sure you like and follow the story so you can find it later. Also, check out my super cool trailer I made for the book on YouTube! For some reason, I can't post links here but if you google this: watch?v=Wo2HxW9L6VQ it's the first video to pop up.

Disclaimer: I don't own the rights to any of the characters or fictional places mentioned, with the exception of the Tyler children, Tenor Williams, and Ellie Smith (they come up later). All copyright of Doctor Who goes to the BBC. I have a bunch of other cameos in here from other fictional worlds, but there are too many to mention.

Enjoy the story!

The kiss was wonderful. It was everything Rose had dreamed of and much, much more. She didn't want to let go, but when the TARDIS engines began whooshing, wheezing and groaning, she had to. She stepped forward, as if the motion would stop the machine. But it didn't, and Rose was left standing there staring at empty beach.

Then a gentle hand slipped into her own, reminding her that this time, she wasn't alone.

"That'll be the last time we'll hear that in awhile," the Metacrisis Doctor said. But there was such a depressing tone in his voice that Rose glanced up, alarmed.

"Are you alright?"

"Yeah."

"Don't worry, We'll hear it again eventually," she said, prying the tiny piece of baby TARDIS from his hand. She looked at it curiously.

"I know. I said I'm alright."

"Rule one: the Doctor lies," Rose said. "What is it?"

"Oi!" he exclaimed suddenly in a higher pitched voice. "What are we doing standing around on this beach for? It's flipping freezing! Do you have a car near here or what?"

"No, we didn't exactly expect to be dropped off in Norway, now did we?" Jackie asked sarcastically. "We'll have to go get a rental."

"Doctor?" Rose ventured. Something was wrong.

"Let's start moving, I can't stand this weather. It's simply awful. Ow!"

His right hand involuntarily slapped his face. "What was that for?" The hand slapped again. "No, you stop it. Bad hand, bad hand!"

"Doctor, what is happening?" Rose exclaimed.

The Doctor shook his head and looked puzzled. "I seem to be fluctuating," he said in his normal voice.

"Fluctu-what?" Jackie asked.

"Switching between my old self brain and my Donna brain. Sort of."

"What," Rose deadpanned.

"Didn't I tell you? The other me, I mean? I've got a piece of Donna in my brain. Oh…he's sad. The struggle, he's so torn. He doesn't want to. She's very, very scared…"

Abruptly the Metacrisis clutched his head in pain and collapsed on the wet sand. Rose and Jackie instantly dropped to his side.

"Okaaay, this is weird," Rose said, sounding shaken.

"Doctor, what is it, what's going on?" Jackie asked.

The Doctor stopped and started breathing heavily. "I'm sorry. It's over now."

"Please explain!" Rose nearly shouted.

"Because I had a piece of Donna in my brain, I was emotionally connected to her. I felt what she felt. You know how she had some Time Lord DNA in her? It was killing her brain, knowing so much. So the Doctor, that is, the one in the other dimension, took it away, along with her memories. The connection broke and it was rather painful."

"So, Donna doesn't remember you, i mean the other Doctor, at all now?"

"No. I'm afraid not. Come on, lets go get that rental. Oh, probably should

warn you, might get mood swings too. Not far fetched, given the personality swings."

Cautiously, Rose and Jackie followed him, Jackie taking over to reach the nearest village. They boarded a Zeppelin and within an hour were on their way back to London. The Doctor and Jackie talked most of the way. Rose said little, save a question about Martha, which prompted the Doctor to tell her whole story. He could not be shut up, except on the few moments where he randomly, inexplicably stopped talking and stared dully at the wall for several minutes. Once he seemed very interested in the fabric of his Zeppelin couch. After Martha's tale he talked about Donna, prompted by yet another personality change.

"How long will it take the TARDIS to grow, you think?" Jackie asked once, while he was in Doctor mode.

"About 16, 17 years, give or take. I'll rig up a lab when we get home."

"Better not be in my kitchen."

""Mum, I'm not an idiot. Oh. That was very random." He pulled out a piece of paper and scribbled another note. "Feels like I'm experimenting on myself."

"Slap yourself again," Rose suggested blandly. "It worked on the beach."

"That might work," he said in Doctor voice. Then it went into Donna mode. "Hang on a minute, are you making fun of me? Sassing the queen of sass are you?" Rose reached over and slapped him herself. "Ow! Thanks a lot! But only the queen of sass can slap the queen of sass!" He slapped himself again.

"Did it work?" Jackie asked.

"Believe so, yes. I wonder why?"

He stared at his hands for the rest of the flight. Jackie and Rose gave up waiting in silence and made plans for Rose's up coming 23rd birthday party for the next night. The Doctor didn't notice, too deep in thought. In fact, he was so engaged that he when he finally snapped out of it, they had landed and were taking a cab back to the mansion.

"I've got it!" he exclaimed. Rose and Jackie jumped. "This hand is part of the original me. That day when the Sycorax invaded and chopped off my hand. Remember Rose?"

"That's the hand they chopped off of the real you?" Rose asked, looking at it in disgust. The Doctor winced slightly, but ignored the comment and kept rambling.

"Yep! It doesn't have direct Donna DNA, which is why it snaps me out of Donna mode and back into the Doctor mode. Of course it's much more complex than that, but it's too difficult to explain...wait. Something's wrong." He looked around stealthily. "Ok, I don't want to alarm you, but I think we've moved without moving. We might have been kidnapped or teleported by unfriendly beings. Remain calm."

Rose looked out the window, unable to look at him. This was not the Doctor.
