Apparently Keltham has never really had a proper chance to be a teenage boy before.
He banters back as fast as he can think of witty replies, and if he can't, he only needs to wait another two seconds and somebody will deliver him a different prompt.
If he had to declare a winner on the basis of clever lines, it'd have to be Asmodia; but that's not all this contest is about, and Keltham does not quite feel like clothed bookreading tonight.
"I suppose I could make you all compete to solve math problems for it," Keltham says, grinning about as widely as he ever has in his life. "I mean, it's possible some of you might be good for something else, but that's the main capability I've seen so far from you all. Am I missing anything I'd find interesting?"
He... doesn't think he's going to be no longer okay for casual sex, as a result of falling in something with Carissa? He's currently looking forwards to selecting one of Ione, Meritxell, Peranza, or Tonia to schedule a nighttime rendezvous, at the end of all this; and Keltham expects that to go basically well, unless he stumbles over some weird new aspect of his own sexuality.
(Yaisa is the one to whom he feels most sexually attracted, in fact; but that would be a little um pending discussion with Carissa et. al. of what happens to, among other candidates, Yaisa.)
(He'll ask what a 'slave' is later, if he remembers; from context it's obviously something like 'masochist' or 'submissive'.)
