Christina Yang is having sex with her boss, because that’s how they do it at the Mayo Clinic apparently. Remember that if you ever end up there and want to argue about the bill. But Yang kicks her boss to the curb once she realizes that he is using her to help build a case against her old timey co-worker and get him fired. But now that Yang has a friend, she won’t let him go so easily, so instead she helps bring him into a modern medical practice. Well, during one surgery anyway.

Richard -- the once and future Chief -- brought in Avery’s mom to consult on his patient’s elephantiasis of the nuts. Yes, just like in The Breakfast Club. Cue a whole lotta uncomfortable looks on the men’s faces and a slough of ball and nut jokes out of the mouth of Bailey who desperately needs a believable storyline this season. Instead the writers have her running around trying to steal everyone’s surgeries for some undisclosed reason and, when she does finally get one, she makes a steady stream of awkward scrotum jokes throughout.

In other depressing news, Arizona is being fitted for her prosthetic leg and is handling it just about as well as you would expect a bitter, depressed and angry woman to take it. Alex and Callie argue about who is more to blame for Arizona losing her leg. Luckily a nearly shamanic prosthetic fitter reminds her that she’s lucky to have people who love her. After a few moments of tough love and some heartfelt looks into the mirror, Arizona starts to shake her funk. The result is that she is nearly collegial to Alex and invites Callie to sit next to her on the couch and watch some reality television.

Meanwhile, Derek Shepherd is reduced to teaching, so Meredith doesn’t want to tell him about her super awesome once in a lifetime tumor surgery. So she doesn’t, because they have a great relationship. Unfortunately of his interns spills the beans and he goes to hate-watch the surgery from the gallery. He tells Owen that Meredith is “bubble wrapping” him, but Owen didn’t get the invitation to the pity party and calls Derek out on his emotional frailty and the fact that he runs to his dumb tin can of a trailer every time he gets a feeling hurt. So that two-minute talk cures Shepherd and when Meredith finally tells him about her tumor, he gets a contact high and she gets a big old kiss.

In the breakroom, Avery and Kepner are still having lots of secret sex before Kepner can reclaim her virginity. It’s all the more awkward because Avery’s mom keeps trying to set Kepner up with nice boys. More awkward for Avery is that his mom is still sleeping with Dr. Webber. So eventually Avery calls out his boss, man-to-man, because that’s a thing that’s done… on television. Avery tells Webber “he’s watching him,” but eventually gives Webber his blessing.

Then Owen moves into Derek’s depression trailer.
