so she has 4 older brothers, they're all originally from boston. parents divorced in 1998 and the mom ran off to cleveland with the guy she left their dad for. cate has very minimal contact with her, but you're free to play that as you'd like. basically i'd just said he's been in town for about 6 months now, but i never specified a reason, so you'd be free to go whatever direction with that, as well. cate is the youngest, as well as the only girl, so she grew up pretty coddled and overprotected by their dad/the brothers. other than that, it's wide open.
