Karo would probably be nice to Alex, she's not one for culling new social interactions so early into her transatlantic upheaval, but if Alex lacks a serious bone in his body she can't see herself bonding tight with him.
And as far as Alice goes, Karo could end up hanging out with her to forget the fact that she's got money, she's got that pesky "I'm rich but I don't want to be" complex tugging at her all the time. Karo's more likely to hang outside the political science that venture inside...unless offered chocolate...or coke.
