Oh man, he sounds charming as fuck and she'll just adore him... somewhat secretly because the whole rough around the edges thing.
She's never been fishing and hasn't gone real camping so maybe they'll have to plan some adventures for the future! She'll also love that he's good with kids because she knows the nephew thing is a turn off to some people. She's more like a second mom than an aunt to him most times but her brother is trying to get his shit together, so we'll see where that goes!
