The Doctor's human counterpart took Rose's hand as the original Doctor faded away in his TARDIS. Once the sound of her engines disappeared and a quiet fell over Bad Wolf Bay, Rose turned to the Doctor and buried her face in his chest. He wrapped his arms around her and held her tightly for a while. Jackie let them be; she knew that what her daughter needed now was time.
"Doctor, I…" Rose started, but then she just laughed. She looked up at him with a weary smile. "It's just so…weird."
"What is?" The Doctor asked.
"You." She replied. "You're him, you're every bit him. But, my head, it's…it's so confused. I just…I don't know."
"Try not to think about it too hard." He told her. "It was a strange thing that happened back there. A completely new thing. I said 'new new Doctor' before, that was nothing compared to this. I've even got one heart! Imagine that! Me!"
"Same mouth on you though, I'll give you that." Rose said.
"Oi!" The Doctor said, offended.
"Ok, except that bit." Rose said. "That is all Donna Noble."
"Yeah, well, just a bit of a side effect, that's all." He said. "So, whole new life, brand new adventure, for me at least. What shall we do first?"
"Well, for starters, you," Rose said, poking him in the chest. "Are gonna need a name."
"A name?" The Doctor replied. "What are you on about? I already have a name."
"Yes, I know, 'the Doctor'." Rose said, rolling her eyes slightly. "But, you need a real name, a proper name. Humans don't go around calling themselves things like 'the Doctor', you know that."
"Ok then, how about good ole' John Smith?" He asked. "That one never let me down before."
"Oh, but that's so boring!" Rose said. "You could be called anything you want! You have the chance to choose your own name, and you're gonna go with 'John Smith'?"
"And what is wrong with John Smith? It's a good name, John Smith. Lots of good people are called John Smith. What would you rather I call myself? Lord Gregory Hastefeld Rafenschelter?" Rose laughed.
"No, of course not" She said. "Fine. If you are that attached to the name, you can keep it. It's your decision anyway."
"I am, thank you." The Doctor said. They started walking towards where Jackie was waiting, hand in hand.
"There is one thing I have to ask you, though."
"Which is…"
"Can I still call you Doctor?"
"Of course. Rose Tyler, I will always be your Doctor."
