[Kitty wasn't trying to trap anyone, least of all Spike. Well, maybe not least of all, but low on the list since it just seems like the best thing for him is to not be around one of the people who got him all nice and souled. Still, paths cross here in the dome and it really only takes a second of being in range before you're bumping against invisible walls which she does now but without any comically great force. She knows to be careful today.]
Hey Spike. [Really looking at him now instead of just catching sight and intending to pass by. The concern is setting in.]
