At Oceanside, Cooper diagnoses the mom as "crazy cakes," which Violet laughs at, but I don't think her psychiatry is much better than that on a regular basis. She tells him the crap piled everywhere sounds like hoarding, which is an obsessive-compulsive disorder that can be triggered by trauma or be genetic. She says she'll talk to her, though this is a hard disorder to treat. Cooper says the kid is great, has a staph infection and is in the hospital, and Cooper's leaving him there until the house is clean. Violet says that might take awhile, so Cooper says his other option is to call child protective services. Violet asks how things are with Charlotte, and Cooper says he can't forgive her, so ... not great.

Addison's office. She and Mark bicker about what just happened. They accuse one another of being wound up, and she finally blurts, "Bizzy's a lesbian," so yeah, she's a little wound up. His turn: Lexie dumped him after he asked her to raise Sloan's baby with him and Sloan. Addison says Lexie's a little young for that, but Mark says, "Do NOT take her side." Then he says, "It sucks," and adds, mostly to pretend he cares, "Your thing sucks too." Addison wonders when they got so sad (Mark interrupts with "old," which is funny), and then asks if he ever wishes they did heroin. It's a dumb way of saying she just wants to put something "on top of it" to numb the pain, like Naomi does with food. Mark gets up and closes the blinds while she talks. He says he hears her desire to numb the pain, and he starts to strip. He says his life is in ruins, and he's about to be a grandfather. He says he doesn't know a lot of ways to numb the pain, but he does know one. He's totally naked behind a strategically placed pillow. She looks at his package and then gets up and makes out with him as he undresses her. They plop onto the couch together. And a million fans of this coupling passed out from the euphoria.
