I liked the argument with Glover once it was devolving completely, just him recognizing what was going on and bailing at the right time. "You need to leave". Not a discussion, he just saw the situation for what it was and got out of Dodge.
Hannah was forced about basically everything this episode though. As mentioned the argument with Marnie, and with Sandy. Just her never recognizing in the slightest how much everything is her fault. I don't need a giant epiphany, but just the tiniest bit of self-awareness.
Ray and Shoshanna's conversation with Marnie was good though. Ray's a really good underused character. The one guy that calls all the girls out on every bit of their awfulness, except the one he likes of course.
