It's all AU.

Jack sat down at the hotel bar, looking around with a small frown. He'd been here for almost a week, and this place was still unsettling. At least Tosh was settling in well, engrossed in her efforts to find a way to predict this place. They hadn't had any luck finding the Doctor, though he had at one point found the TARDIS.

And he still hadn't run into anyone called Jack Harkness yet.

"He has to be around here somewhere." Tosh leaned against the side of a building, reaching down to pull off one shoe, rubbing her heel. "I'm sure he wouldn't have gone far."

Jack put a hand under her elbow to help her keep her balance, keeping an eye on the street for other people, a small frown on his face. "I haven't seen anyone since we arrived, Miss Sato. Or the TARDIS."

"Well, we haven't searched everywhere yet." Tosh put her shoe back on, giving him a small smile. She tucked her hand into his offered arm, stepping out into the street once more. "We'll find him, or someone, sooner or later."

Jack returned her smile, recognizing the determination she'd shown when he first met her, only a few days before. That somehow, she'd find some solution to the problem of getting home - or finding the Doctor, in this case. He looked over the street as they continued along, spotting a familiar tousled head, even if the outfit wasn't quite what he remembered the Doctor wearing.

"Doctor!"
