Considering it had been rather hellish to help set up, you bet your ass that Desmond is running the obstacle course. Climbing was never an issue before he lost his arm and, with practice, he'd like to make it less of an issue now.

That still doesn't mean he can't fall flat on his ass, much as he tries not to. Part of the course has one of his favorite options, requiring a backwards vault, a quick turn and a grab of the ledge opposite. The first time he instinctively reaches with his missing right hand, plummeting like a stone in a pond with a sharp, muttered "Ah, crap!" Desmond twists in mid-air like a cat righting himself, so he lands tucked into a roll instead of on his face, but it's still a disappointment.

If he catches a watcher though, he'll flash a confident smile, and crook two fingers at them. Nope, no lolly gagging, friend. Let's roll.
