Sam's actually pretty impressed by the maneuvering. He'd seen similar stunts pulled, of course, but he'd known those people could do it. He was still learning about the people he was "stuck" with and the scrubs they were wearing made it always difficult to tell where someone came from. Until they demonstrated skills, they were all unknowns and virtually the same. The man definitely moves with the confidence of someone who has spent a lot of time with heights and probably doing some pretty dangerous work -- given his skills demonstrated earlier.

That or he just really enjoyed parkour.

Sam is further surprised by the hare, of all things, set up nearby. How'd he miss that? More importantly, how had the man caught it? Were their more? That would be great actually and Sam actually smiles, "You're going to be Mr. Popular pretty fast if you can manage this." He then realizes what Cougar said and turns back to him, "You sure?"
