Another look, first to Jack and then down to Velcro -- after all, the dog has a far better sense of smell than Sebastian does.

"How so? You'll have to forgive me, I know I'm a bit too curious, and I'm not really sure where and what the taboos are." He's half-tempted to lean in and sniff, but he has no way of knowing if there's some sort of strange, future-human smell-based defense mechanism involved or just what sort of 'different' it could be. (Before you laugh, consider how bizarre their respective canons are and then tell me that there's no world where humans haven't developed just that thing.)
