It's all AU.

Jack went back to his TARDIS, to make sure she was OK, and to add the information he'd discovered.

He found the right tree, and was about to unlock the ship, when someone he hadn't seen for hundreds of years walked out the shadows.

"She's mine," Jack told him. "Working chameleon circuit, too."

Lucy was staring at a blue Police Box tucked away in a corner of the library. "Well. How long have you been there? And who do you belong to?"

The Doctor perched on a stool at the bar in the hotel. "What's good to drink?" he inquired of the person next to him. "I'm feeling experimental."

The Master was in a deserted cafe running his laser screwdriver all over the server android.

...It wasn't as kinky as it sounded.

Jack was gazing into the window of a clothing store, at a mannequin wearing what appeared to be an exact replica of the coat the older Jack had been wearing.

Jamie sat down next to Jack, sprawling a bit in his chair. "What can you tell me about Captain John Hart?"

He was supposed to be vampire hunting, but after turning the sadistic, obsessive, lonely, and only recently at all sane Master onto the problem, Jack was feeling quite a bit better. About the vampire.

His talk with Jamie reminded him of another situation, so he started looking for John. In bars, of course. When he found him he slid onto the stool beside him. "Hey, handsome. Buy me a drink."
