SPOILER ALERT: this blog is published after the US transmission; the UK broadcasts the episodes a week later.  • Read Rebecca Nicholson's episode four blog  As if there was any doubt that Hannah Horvath was an only child: here's an episode title pointing it out. Hannah followed up last week's invention of a dead cousin with self-centredness so shocking you suspect even Marnie wouldn't go there, and now it seems to be coming back to bite her. Each season of Girls has done a fine job of ratcheting up the tension at this point; it pushes discomfort and awkward situations together with increasing frequency until imminent doom is certain. After this, it seems like Adam and Hannah may not be enjoying the happy life together that they were at the start.  Lena Dunham doesn't get enough credit for the sheer absolute awfulness of her characters. Hannah was a baby, a brat, and a staggeringly selfish human being this week, and it was mesmerising to watch. I know to most viewers, these Girls (and I include the boys here) are barely functional, but they're just functional enough to make their horrific behaviour all the more shocking by contrast. It's a delicate balancing act and this episode showed that off perfectly. Hannah not only pesters David's wife for a publishing contact at his funeral, she fails to ask her father what he had a procedure for, then kicks Caroline out for being insufficiently sympathetic about her book deal collapsing. She ignores the clearly desperate Marnie and even makes Adam and Caroline's argument all about her (the request to not say "fatty" wasn't aimed at either of them). She's reprehensible. And I loved it.  Much like Marnie fucked the pain away with Elijah in season two, she does the same here with Ray, who has just informed her of her many flaws in excruciating detail: "extremely judgmental", "unbearably uptight", "uses people", is "a huge fat fuckin' phony". With grim inevitability, they have awkward, clumsy sex which Ray then asks her to keep quiet about. He really earned her "go fuck yourself" there. Also, cute cat!  I know she had a lot to do in rehab, but the time has come to give Jessa a storyline. Smoking an e-cigarette and getting a job in a kids' clothing shop is not that.  She didn't say much but I love the way Shoshanna's dialogue has been written this season: when she talks about her "recent high jinx" she sounds like a character out of time, almost as if she could be in The Group.  A relatively quiet week, but the song that played us out was Matt Costa's Good Times.  Writer, director and actor (and Don Draper's real-life other half) Jennifer Westfeldt played David's shock wife.  • The Girls title screen was (almost) entirely black this week, which was a nice touch.  • I'd like someone to explain Hannah's cropped lizard T-shirt to me. I know she likes to add quirk to her fashion, but this was borderline Gaga.  • More insight into Hannah's writing. I'm certainly intrigued by "the handjob kidney stone" and I really would like to know what happened with the glitter pens.  • I'd also like to know how this makes her "Mindy Kaling meets Joan Didion" or "Kathy Griffin on truth serum" (as if Kathy Griffin needs truth serum).  • "Be safe and stay warm": has there ever been a less appropriate post-coital sign off than this?  • We saw a different Hannah in the meeting that landed her a short-lived book deal. She was quipping like a stand-up in there.  • I had genuinely wondered how much Hannah and Adam's rent was, and now we know: $2,100 a month.
Rebecca Nicholson's episode recap: Hannah's behaviour is becoming increasingly self-centred, and it's wonderful to watch. But Jessa and Shoshanna need more to do
