A nondescript pub, somewhere in London.
Idly leaning back in his chair, Jack took a sip from the tumbler in his hand before sliding it back onto the table. He was studying the face of the young woman who sat across from him and remarked almost absently, "You're very pretty, I must say. Remind me so much of an old friend of mine. Magnificent woman, haven't seen her in ages on account she's trapped in a parallel dimension." He paused, seeing the ghost of her face and spirit in this sprightly young girl. "Oh… I loved her but she wasn't for me." His eyes traveled away from her face momentarily then back to it before a slow smile tugged at his lips, "There are other fish in the sea, however…"
Inclining her head with a sly glint in her eyes she winked at him, "Best watch your step, Captain. M'dad is a time-traveler, too, and from what I hear, he's got a bit of a reputation for putting people back in their place…"
"Oh-ho-ho, a threat?" He grinned handsomely, his voice solid, "I promise you, this deal's legit."
"No, not a threat," she smiled innocently enough. "Merely something to remind you to behave when you buy me that second drink. Provided we actually get to the business of discussing your proposition, of course."
"Only one man in this universe could possibly get me to 'behave', gorgeous, and I doubt it's your dear old dad. He's probably a great man, no doubt, but the Doctor's one of a kind."
The way her face brightened confused him, and so did her words, and her eagerness. "You have met dad! Are you a friend? How did you meet him?"
Captain Jack Harkness stared blankly for a protracted moment at the pretty young blonde girl in front of him as the resemblance to a second old friend of his bubble to the surface.
His face paled and his lungs forcibly expelled what air remained in them. He was relieved he'd set his glass down, for he certainly would have dropped it.
Jenny looked blithely concerned. "Captain?"
Flirtatious demeanor fading as his mind began racing in all kinds of directions, he bit the inside of his cheek and murmured, "Oh, I'm so gonna get it now…"
