Confusion can overpower logic. In this case, I think that the MC is just trying to make sense of it. MCxQuestions+Aveline=Answers. That, and keeping it bottled up inside could actually make it worse for him. Also, I think it would be apparent before too long to those around him that he "Ain't from around these parts."

Fair. I can agree that being disoriented can make you say and do stupid things when you shouldn't, that's still no reason not to think of something like, 'I'm from far away and my memory is really fuzzy from being attacked... Sorry, but could you help fill in the gaps for me til I get used to things' or something like that. Point is... there were literally a million things he could've said other than... that. Sorry, I guess I'm just super tired of MCs being so needlessly dumb where even the tiniest thing can kinda lowkey trigger me.
