The Brodys and Waldens get invited to this horse farm in Virginia... Wait, back up. Quinn's okay. Repeat, Peter Quinn is going to be okay.
So the Brodys and Waldens get invited to this horse farm in Virginia for a fundraiser that's nominally for Walden's presidential campaign, but really is for cheering on Nick Brody for VP and eventual President. Brody knows damn well he's not gonna make it another eight years, and the unabashed man-adoration (and creepy rubbernecking from some of his dumber admirers) makes him extremely uncomfortable about how he's in actuality a traitor and a sumbitch.
The pressure is all too much, especially after Mike's gossip last week forces him to tell Jessica he killed Tom Walker, and he eventually kind of loses it on Carrie and Quinn because he is out of his depth and nobody will tell him anything, and Roya always yells at him, and he feels very impotent.
Carrie's solution: Get him to bone her in this random field on the farm. Brody's response: Very nearly an unqualified yes, until he realizes that not even Carrie can be sure whether she's manipulating him. It is a beautiful, complicated, sexy, depressing, bewildering, miserable, wonderful, magnificent mess as usual. He finds his true peace in the property's swimming pool, meaning he's fresh and ready for yet more bullshit when Jessica tells him about how their daughter killed a lady and the Waldens want to cover it up.
Finn takes off in a towncar somewhere, because he knows his parents will probably end up killing the whole Brody family if they fuck up the dynasty, but dumb ol' cornpone Jessica and Dana get uppity about "the right thing to do" and act like poor people, and then Brody decides to take a stand and drags Dana off to the police. At which point David Estes -- who is there purely in case Brody goes off the rails in some way, which is obvious because he's the only black person at the entire thing -- calls Carrie, who steps in to tell him that if he does this and alienates the Waldens, he'll lose his entire immunity deal. So now Dana has Carrie just randomly popping up in her life, and assumes this is her father being a smooth criminal politico, and she's just fucking had it too. Everybody has just had it.
Meanwhile, Saul spends the entire episode at some supermax prison playing out its themes in counterpoint with Aileen Morgan, that mild-mannered jetsetter terrorist from last season that he had the wonderful road trip with. Things have not, let's say, gone splendidly for her since then -- like, she's gone Gollum blind and tends to throw her shit at you. Her only price for info on El Mysterioso, a cell with a window, takes most of the episode to obtain -- during which time he wines and dines her and they remember that they are actually pretty cool as friends -- so that by the time Peter realizes she's given up random fake El Mysterioso in return, she's managed to commit suicide using just the ingredients of a Lunchables and some ingenuity.
Saul cries for the terrorist Aileen, but not too much, and Carrie cries because she is in love with Brody, or is she, and but you know who is not crying? Peter Quinn, because he is doing just great with that GSW through the abdomen and he's back on the job. Oh, he has the coloration of Bill Compton at the moment and he did flash Carrie his wang like a psycho or a sleepwalking grandpa, but mostly, he is doing great. Which I think we can all agree is a relief.
