[She brings up a valid point. Most regular people do not have the luxury of using superpowers to get them out of things, nevermind the fact that most normal highschoolers don't have a lick of defense training. He does recall that, while Fukawa's world is now in the thick of what seems to be the apocalypse, it wasn't always that way. What strikes him as peculiar is that she doesn't mention what happened to the second girl, meaning that death or a fate somehow even worse than that was the likely result. Rex doesn't do anything to rebuke her first jab, but at the second, he tries to lightly jest with her.]

...Nah, iiiit's pretty much all dick-jokes and bad puns. I've got a few zingers here and there! But those are mostly improvised.

[When she mentions the split personality, he falters. Rex resists the temptation to make a jab about her being crazy, clinically speaking. From the little he has managed to understand about her nature and her past, she has the tendency to take comments like that to heart.]

Split personality, huh?

[Somehow, he wonders- Would a demonic possession be better or worse? At least then, everything the crazy entity did wasn't... Her fault. This situation blurs a few things.]

Are there just the two? It sounds like you really don't wanna talk about it.
