[Alistair mulls over the answer carefully before he tries saying anything. It's clear Mystique really means what she's saying about her brother. She believes he wouldn't use whatever magic he has to hurt people and Alistair hasn't even met the man. If this Charles shows up in Wonderland then he can see if he agrees with her assessment. Until then it doesn't really matter and he's not about to say bad things about her family to her face without reason.

Finally he nods, accepting the reassurance and relaxing back in his seat once more.]

That's not a bad thing, wanting people to do what's right. It's better than expecting the worst of everyone.

[The worst that can be said about that way of thinking is that it's too naive. So long as her brother never got himself hurt because of it then it's the kind of attitude that more people should have, in his opinion.]

Besides, with the... mind reading thing he'd be hard to take advantage of.
