@Podi125 I mean, I agree with everything you've said, it was unnecessary and a massive dick move. But he's a kid himself, kids act stupid and overreact all the time. His reaction just appeared to me as immature, not ill-intended.
So yeah, I don't like him all that much, he seems way more bratty than his sister. But the fact that he's a kid means I'm looking forward to see how his character develops in the future.
