Jack just laughs when Spike shoves him down into the floor and acquiesces, for the moment at least. He'll fight back, because that's half the fun, but he'll also let himself be taken down, because that's the other half of the fun. He stares up at Spike, panting, remembering something about a Chinese Slayer, and remembering too what China was like in those days.
"Boxer Rebellion, huh? That's when you were here, too?" he asks, because that's one hell of a coincidence. "This where you killed her?"
((OOC: Heh, I always wanted to do something with the fact that Jack said he was in China during the Boxer Rebellion!))
