"Mmm, I don't think I'm inconsistent. I can consistently predict the kinds of stuff I'm going to do, usually! Like, I think if someone had told me beforehand that Rufus would mention my parents' situation to me I would probably have noticed this would make me unreasonably angry and then taken steps to prevent myself from being angry. The surprise was a decisive factor, there. And I can totally predict that I will sometimes tongue-flick at random people just to watch them go 'eep.'"
