Asriel lets out a surprised noise (which sounds suspiciously similar to a bleat) and instinctively raises his hands to catch the human that's sort of falling over on him. And yeah, he's not really hidden all that well. His hoodie was really not designed for this at all. His muzzle pokes out of the hood no matter what he does, pretty much, and there's just not much to do about your hands being furry and clawed.

So........this is weird then, huh?

"Sorry!" he blurts, snatching his hands back. Gosh, he didn't get them with his claws or anything, did he? They aren't all that sharp, but y'know - he's pretty great at hurting people, generally!
