She thinks he's nuts but he explains that they have to rewire the brain and remind it of what happened. He tells her there are different treatments but for each person it's personal -- one guy he knew in the army had to stab his prosthetic with a screwdriver. She finds this all insane but when he asks if the pain is better she realizes, shocked, that it actually is. He asks what Callie thinks and is disappointed when she admits that she hasn't told her what's going on, given that she is an orthopedic surgeon and could really help with this kind of thing. Arizona freaks out that she was just starting to feel like a wife again, rather than a patient, and that she can't go back to being a patient especially over something that isn't even real. Owen actually does understand, so he tells her that he will work with her to help her figure it out.
Now that Cristina realizes the African orphans might have all sorts of different cardiac conditions she'd never see otherwise in the US, she thinks they are the greatest thing since sliced bread and tells Meredith all about her new love. "They're exotically diseased, beautiful little train wrecks." She's on a high from the fancy surgery she just did, and is so excited that she doesn't notice that Mere looks barely able to hold her face together as she walks down the hall with a cooler. She's on her way to go pick up Brie's new liver, but she asks Bailey if she can get a different intern to go with her. Bailey is unimpressed that she's ready to give up on Smash already and reminds Mere that she often wanted to kill all of them when they were interns and that they actually pulled serious crap like cutting LVAD wires without getting dumped from the program. She just tells Mere she's got to suck it up.
Derek goes in to Jimmy's room and finds him and Carla exclaiming of a cookie the size of a pizza that someone sent him, but since he can't eat now he's just staring at the thing. I think the not eating beforehand really is one of the worst things about surgery and it's during those hours you also realize how every single commercial on TV is for some kind of food or food-related thing. Everything's all hunky dory giant cookie jokes until Carla realizes how serious Derek's face is, and he admits that the tumor has progressed. All of the risks -- little things like Jimmy possibly going deaf, half of his face basically melting, death, etc. -- are bigger now. Derek tells him to take time and think about what he wants to do but Jimmy says that he already waited months while Derek was recovering and he wants to try it. Carla can't handle it anymore, and she runs out of the room.
