"To find us," Jack said with a grin, knowing she would find absolutely nothing at all about that card except for the address of a particularly lovely plaza with an old glass building on it and an interesting water feature. This dimension's Millenium Centre was intact and not a hole in the ground and Jack was nothing if not a masochist. "If you decide to come, I'll show you what we do. If you don't...no hard feelings, Miss Simmons. But we probably won't meet again."

He offered her his hand for a shake and nodded. He had a few others to go and see still but perhaps she'd come to find them all and then...well, he'd have the Retcon ready just in case but he didn't think he'd need it.
