Balthier pretends to be a loner but he LOVES to talk haha. He fancies himself literally "the leading man" despite the fact that he likes to direct others and even run support. It sounds like their dynamic will be fun.

I LOVE friend who bullies you to look nicer scenario.

I think I also noticed you said he wasn't sure about unaligned or Guild yet. I was going to have Balthier also organically deciding, so could be something they could bond on or scope together.
