The raised hand catches her attention. She'd noticed him as she approached for the simple fact that he's on a rooftop too, but he's not there for the same reason she is, and hardly looks like he's going to come join her in her run, so Rikki decided that though he could probably see her, it wasn't really a concern. But when he waves, it seems almost rude not to come over and say hello. It's not like she has much else to do anyway...

It takes a little creative maneuvering, running up and bouncing off walls, to regain the little bit of height she lost since she left her own building, crossing over to the last building in a jump that'd kill her if she missed - but she won't. She used to run along the tops of bridges back home just for the fun of it, and this? This is nothing.

She lands in a crouch, and flashes the man as a grin as she straightens, pushing her goggles up onto her forehead. "Hi! This is another building for... uh... non-kedan, right? I'm new here."
