kas is a recovering drug addict, although he's been clean for four years and she probably doesn't attend NA if she's still into that scene. she's a fair bit younger than him (he's 35) but maybe she's some sort of bad influence that he sees now and then at the couple of bars he sometimes goes to? i'm envisioning something like her popping up every so often and if he's there, he probably finds her pretty entertaining and is happy to hang out with her and drink more than he should (he's supposed to lead a teetotal lifestyle but he's usually okay if he has a couple of drinks, so in her company maybe he has a couple too many or something?). i think he'd like her, but they probably don't have a friendship where they socialize a whole lot outside of their drinking sessions. does any of that sound appealing?
