Gawking, Gwen snatched the bag from his hand and took a look at the contents, shaking her head and staring at him somewhere between awe and annoyance.

"Jack Harkness," she almost spat, but not without a tone of teasing in her voice. "I spent days followin' up on you, searchin' high and low and all anyone can tell me is that you don't actually exist. And you have my bloody birth certificate."

She dangled it back in front of him, raising her eyebrows. "You're missin' a few things. My favourite colour is red. I love bowling and red wine and Big Brother. I'm great a laundry, rubbish and the washing up and steak pies make me a bit sick." She shook the bag for emphasis, narrowing her eyes playfully. "Don't think you have my life in an evidence bag, Jack. You don't know me any better than I know you."
