yeah, I think Ali is being precautious with Rue cause as he'd asked her if being with Jules and being away from her felt similar to being on drugs and the withdrawal symptoms so a relationship when you're still recovering could be dangerous but I really hope it works out.
I think Kat still doesn't trust herself enough that she could accept someone's genuine affection. she's very insecure like most of the characters and so she throws herself at strangers instead. I hope she will learn in time that this isn't right.
I felt so bad for Cassie but I also saw some truth to what McKay was saying. I know it must've hurt her like hell but Nate really is such a jerk if he sees people in happy relationships while he's not in one he'll try to ruin it every way he can. so it's a really messed up situation but I really think McKay didn't mean to hurt Cassie
