The article below contains spoilers for "Boys," the February 17th, 2013 episode of "Girls."
"Girls" is, as advertised, a show about a group of young females, and the guys in its world tend to be shown only through the perspectives of the main characters, coming across because of this as half-understood creatures who've been slower to emerge as full-fledged figures in their own right. In the first season, a scene of Ray (Alex Karpovsky) and Charlie (Christopher Abbott) poking around in Hannah's (Lena Dunham) room was the only moment involving the boys on their own that I can remember, and even then they spent that time talking about the ladies in their lives. It's a choice that's made the show a sort of ideal fit for the Bechdel test, in that it's actually the male characters who are portrayed only in fragments as they relate to the female leads, but the rare moments we do see the guys outside of their roles as prospective, current or past boyfriends provide interesting breaks from the show's standard operating procedure.
Adam, with his flat full of tools and a feral animal, may seem, as Ray puts it, "very masculine, very primal," but doesn't end up bolstering Ray's sense of manhood in any way. The two are undergoing moments of quiet emotional crisis, as becomes clear as the venture falls apart -- Adam is, despite his insistence, nowhere near over Hannah, while Ray's distressed about being a 33-year-old self-described loser who secretly moved in with his college-age girlfriend without telling her because he was in between apartments. Though once again their conversation revolves around the absent women in their lives, both are fighting their way through personal issues that seem to go beyond their relationships.
While he doesn't get a storyline to himself in the same way as Ray and Adam, even Booth Jonathan (Jorma Taccone) gets to open up in "Boys." When he makes it clear to Marnie (Allison Williams) that she's not his girlfriend in a way that's accidentally but breathtakingly cruel, he does get a moment to share his side of things, and while its sudden it's not unfair. After having Marnie host his party in what he saw as an evening of employment and she saw as a step in their relationship, he calls her out on why she wants so badly to be with him, and after getting her to admit that she fell in love with the idea of him and with being the girlfriend of a famous artist, notes that nobody knows him and that everyone just uses him. It's a reveal that comes a little easily, but it's one that provides an entertaining turnaround -- he's just told her she's the hired help he sleeps with, and yet she ends up comforting him.
