It's hard for Faolan to understand much of anything of a metaphysical nature, with absolutely no abilities himself. Watching people with them, it mystifies him some times and frustrates him in others. This situation being perhaps one of the former. Watching Lancelot make his way up a vertical wall to a window two stories up? Definitely the latter.

"That makes two of us, then, I suppose," he says, somewhat apologetically. At least he understands he's not the best people person.
