He gets a kick out of Karis. He likes her. The way she acts about the whole undead thing has is making him think juuust a bit about what her feelings about undeath are, because he's so damn proud to be a demon and only laughs at the people who get all huffy about him and she seems to take it a personally.

He doesn't really agree with her on the whole military thing but that's a cultural difference -- demons don't HAVE a military, really, it's just 'the strongest guy is in charge'. He definitely thinks she'd be a really decent compatriot minion if she could just get over being so damn prickly and start playing along with the rest of the ship.
