[For Kitty's part there are no real expectations. She's never sure what's going to happen with Reid. Will they be laughing over something, learning something about each other, making out or revealing some painful truth about their pasts? Probably a little of all of it. They're used to living intense lives. Maybe it's some leftover from that. Pacing goes out the window when they function best under the pressure.
Speaking of pressure, she'll add just a bit more to the kiss. She's just going with what feels good to her.]
