From Rose's point of view, the events of Turn Left, The Stolen Earth and Journey's end never took place. On Pete's world, they knew something was happening as stars were going out but Pete had sent Mickey to find out what it was, using a portable device and seeing glimpses of the Doctor but never telling Rose, just in case it wasn't really him. She never knew Mickey had found him and Mickey, on his last trip back had said if he found his way back, he was going to stay. Rose had pleaded with him to take her back with him but they knew it was too dangerous. Mickey said he would come back if he didn't find the Doctor again.

THE ultimate 'Is Alec Hardy the Doctor story'

He remembered most things, such as being created and a certain red-headed sassy temp from Chiswick. He also remembered wiping out the Daleks - again and every time he thought he'd done that, more of the blighters came back, they always survived, one or two of them got away and started all over again. Either that or he went back in time and found past versions of them or they slipped through the void into 1930's Manhatten and even then, one had got away.

Now he was back in the Tardis, surrounded by who he thought were his friends and his other self was glaring at him, for destroying the Daleks, for committing genocide but how could he have the nerve to accuse him of that? Did he just stand by and watch Davros create another empire and try wiping out all life in the universe again? Some choice he'd had.

The only regret he had was that it was him who had the nerve to actually do it, his so-called superior twin didn't have the guts. Not that he hadn't himself wiped out a few species along the way. He had some room to accuse him.

Donna was standing by his side, smiling. "Oi, spaceman, cheer up. We're going home. This is going to be fun, travelling with the two of ya."

He thought about that. How could he travel with his twin, knowing what contempt the other one had for him? He walked away, walking around the console and his other self was watching him. Suddenly, the Tardis jerked and everyone began cheering, Martha, Jack, Sarah-Jane and Donna were hugging each other and Donna was pulling Sarah-Jane out of the way to hug Jack – typical. Mickey was more interested in Martha.

He didn't even know who this Mickey was. Was he supposed to know him? His other self obviously did or he wouldn't have let the man into the Tardis. He had been on board the Dalek Ship when he and Donna had burst out of the Tardis. There hadn't been time to ask.

They had landed, in a park by the look of it. Donna was calling her granddad, Sarah-Jane had said goodbye to him and was outside talking to his twin. Martha had just been talking to Mickey and had said goodbye to him, so had Mickey so he must have known him even if not the other way around. They had gone after Jack, who was trying to persuade Martha to quit working for UNIT and Mickey had muttered something about there being nothing left for him where he had come from though he didn't know where that was supposed to be. Something about his grandmother passing away peacefully.

Donna was sitting on the jumpseat and the other Doctor came back in.

"So, they've all left then? What now?" the clone Doctor asked.

"That's up to you. What do you want to do? You can't be left on your own in our universe, not after what you just did and you know it," the Doctor in brown stated.

"Don't tell me the thought never even crossed your mind? Well it must be the human part of me that was showing some compassion for the rest of the universe because if I hadn't destroyed them, they were still in a position to slaughter everyone. Or doesn't that count? Are the Daleks more important than the rest of life out there?"

"I'm not debating it with you. You know the reason why I wouldn't have done it."

"Do I? Just how much are we alike?"

They both stared at each other until Donna broke the stalemate.

She turned to the Doctor in brown. "Take him to Rose."

"What? Who's Rose?" the clone Doctor asked.

The other Doctor and Donna looked at him. "What do you mean? You know who Rose is." The Doctor in brown was surprised.

Then he realised, they had never mentioned her since the creation of his clone and it seemed he had no recollection of her. He would have to discover her for himself, he couldn't force him to love the same woman as he did. Mickey had explained that Pete had thought it was too dangerous to send Rose to see what was going on, he had been sad that she hadn't returned but maybe, if they landed on Pete's world, he should go and see her. Anything was possible until the gap closed again, maybe there would be time for one trip.

"No or I wouldn't be asking. So is someone going to tell me? And while we're at it, who was that Mickey? He looked familiar, didn't we meet him in that alternate universe but his name was Ricky? Funny, I swear I used to know him."

"Just how much do you remember from the alternate universe?" the other Doctor asked him.

"I remember being in the cyber factory and Pete Tyler, the head of what was known as Vitex in that world being there, his wife had been taken inside and converted into a Cyberman. Then I remember being on the roof and hanging from a zeppelin. Then I went back to the Tardis and that Ricky came back with my suit and someone called Jake was there. I remember other things but I think that just about covers it."

"Don't you remember who else Pete Tyler was?"

"Nope. Should I?"

The other Doctor shook his head. It seemed his twin had lost all memory of Rose Tyler and her family and friends.

Before either of them knew it, Donna was taking charge.

"I don't know much about Rose, only what you told me but I think you loved her. Maybe you should go and find her. We've arrived in that parallel world." She was walking around the console, now she knew the workings of the Tardis control panel and learned why it rocked about all over the place.

Both of The Doctors looked at her. The one in brown picked up on what she was saying. He had said goodbye to Rose, on the exact same beach they had just landed on. He now had a twin, someone who could give Rose what she needed – him, if she still wanted him.

"You brought me here, to the alternate universe? Just as well, I wouldn't want to be in your way after all and you obviously don't trust me. As for this Rose, who was she to me, or rather to us?"

"She was our travelling companion, since before our regeneration."

"Oh, you mean when we were all ears and leather," the clone chuckled. "Why would she have wanted to travel with me when I looked like that?"

"Don't scoff. Maybe she saw something in us."

"Whatever. So are you going to let me out then? The sooner I get out of here the better. Don't suppose you have a spare Tardis?"

"It doesn't work in this universe – remember? We crashed landed here the first time. It's only because of what's just happened that we just got here and the gap will close again soon. If you stay here, there's no way back."

"Good. Why would I want to go back?"

They all stepped though the doors onto the wet beach – Bad Wolf Bay. The Tardis was making warning noises behind them, they needed to leave soon or be trapped there themselves.

The Doctor in brown went in his jacket pocket and got out the psychic paper and his sonic screwdriver. He could always make another and get more psychic paper.

"Take these, you may need them, oh and here – take this." He brought out a piece of coral from the Tardis. "You can grown your own though it will take you a while. It will only work in this universe."

"No thanks, anyway, why would you trust me with a Tardis? You said yourself that I was dangerous."

"Suit yourself. We have to go now but remember this, neither of us wanted this, it was unexpected though I think I know now why I got my hand back. Go find Rose Tyler, she'll help you, explain to her how you were created. She's the only one in this universe that will understand you. You only have one heart but your other biology is superior to humans, so stay out of trouble or they may still lock you up to see what makes you tick. You'll heal faster if you get injured and your senses will be heightened plus your knowledge is the same as mine and you know what that entails so don't go showing off."

"Anything else?"

"Yes, you can still come back with us, we're still brothers."

"No, we might be that biologically but that's all. Will I still feel the same guilt as you about what happened to the Timelords? I don't feel anything."

"No, probably not. Still, although we can't agree, be safe and I hope you find a home here and if you do find Rose, don't be afraid to tell her what you feel. I made that mistake and I've regretted it every day since I left her here."

"You left her here? How could you do that?"

"It wasn't by choice. She has her mother and probably a stepfather by now, she'll explain it to you. It's not long after I left her here in the terms of our universe, they are ahead of us here, don't know exactly how much so she won't have forgotten me. She's probably mad at me and I really deserve that. If you can't do anything else for me, just do that one thing – find her and you won't regret it, I promise you."

The Tardis gave a deeper warning – the cloister bell.

"We really have to go now. Goodbye brother."

Donna stepped forward and kissed his cheek. "Bye spaceman – look after yourself, even if it's just for me."

"Thanks Donna, you were a real friend. Just you go be magnificent. Goodbye Doctor."

The two of them stepped back inside the Tardis and the clone watched his twin and Donna fade from view. Whatever he was going to do, he had to get off this beach before nightfall. He had no recollection of ever being here before. Maybe he should go look up this Pete Tyler, he may remember him if he helped stop the Cybermen. Was he any relation to this Rose Tyler or did they just happen to have the same name?

He walked along the beach and found some fishermen loading up a van. He approached them and asked for a ride into the nearest town. He didn't understand what they were saying, not now there was no Tardis to translate for him. That was the only thing he was going to miss. One of the men understood he wanted a ride and pointed to the back of the van so he got in.

A short time later, they were pulling up in a town square and he got out. He would have to sonic a cashpoint to get some money, then remembered he had no account to hack into in this world, he had used to get money from an old account set up by UNIT back in the old one, one they used to pay him for the work he used to do for them and had never touched except in emergencies.

Still, he had the psychic paper, he could use it to get a room at least, he could bluff his way into staying a night or two and get out of Norway, maybe hitch a ride or go to the airport or was that the zeppelin port? He remembered the zeppelins, did they even have planes here? He walked into a hotel feeling cold, tired and hungry, all new senses to him but if he was going to make it on his own, he was not going to be known as the Doctor any more. He had a whole new universe just waiting for him, he could be whoever he wanted and none of that John Smith lark either.

Approaching the desk, a man looked up. "Yes Sir, can I help you?"

"I hope so. Can I get a room for a few nights? I've found myself stranded. Got separated from some friends and I'll have to wait for them to come back for me." Well it was sort of true, he was just in for rather a long wait.

He had no idea where he was going to go or what he was going to do. He could teach, he'd posed as a physics teacher once and taught at a boy's military academy back in 1913, he'd even once or twice pretended to be policeman.

The man behind the desk was getting a key and pointing to the register. "Sign here please, Mr?"

The clone Doctor grinned. He had to choose a name, one he was going to stick to, get himself established as but he would have to check no-one else had that name before he went for it. He could use John Smith for now but it would look a bit dodgy. So he picked up the pen and signed his name – Alec Hardy, Glasgow.
