Kevin pops down off the latest conquest (a big, floppy cargo net you're supposed to climb) so he can get a better look at this guy. He didn't expect to run into anybody, and it shows.

"Um, I don't know if it's like... actual parkour really, but I know how to do some stuff?" he answers. "I don't need nobody to know I've been messing around down here, it's fine."

And for the better, probably. It occurs to Kevin that you can maybe get your privileges revoked for doing dumb dangerous stuff on equipment. Disappointing, but likely.
