So, Meredith, what is this week's theme? "We go into medicine because we want to save lives. We go into medicine because we want to do good." Cristina is dancing awesomely in Mere's bedroom, something which I didn't realize until now I missed so much. It's totally reminiscent of the party from Season 1, in such a good way. VO adds, "We go into medicine for the rush. For the high." Cristina is shaking it -- kind of like I do when I'm alone in my apartment getting ready to go out for the evening, actually. Meredith leans on the doorframe, watching the show. Her disembodied voice continues, "For the ride." Cristina sees her and, without missing a beat, accuses her of not dancing. Meredith whines that she's too tense to dance but Cristina counters, "Which is why we're dancing!" This doesn't inspire Mere; she just goes on to explain that her problem is that she's sleeping with a guy who is dating. And she doesn't care about him dating Sydney, but rather the person he dates after Sydney. So she must mean Rose, the nurse who has actually been around the whole time and helping on surgeries. And don't worry, I'm not giving away any future plots, since I don't actually know any -- I just think it couldn't be more obvious why we've all "totally coincidentally" just noticed Rose for the very first time. Mere continues babbling, now about how she should probably stop having break-up sex, but mercifully, Cristina tells her to shut up and dance. Her voice-over doesn't shut up but says, "But what we remember, at the end of most days, are the losses. What we lay awake at night replaying is the pain we caused, or failed to cure." Mere starts dancing, rather forcedly at first, but she's soon into it as her voice continues, "The lives we ruined or failed to save." Meredith then comes to a decision, but it's not exactly what I thought it was going to be, which was fully breaking up. She declares that she's going to tell Derek she doesn't want him seeing other people. She declares, "I'm going to tell him, and I feel good about it." Cristina yells, "Dancing makes you brave!" Izzie comes out of her room, sees the dancing, and puts on a classic Izzie stinkface while Mere's VO concludes. "So the experience of practicing medicine rarely resembles the goal. The experience too often is ass-backwards and upside-down."
Izzie flounces over to George, who appears to be sleeping in the library in a sleeping bag these days, and declares angrily, "I'm so sick of Meredith and Cristina and their stupid love affair with each other." Sorry you hate actual best friendship, Izzie. It turns out that the lasting ones aren't all about breaking up marriages, and are more about being close and there for each other, which you don't seem to grasp. She continues to rant about them rubbing it in others' faces and how stupid they are, and George chuckles at her and says it's too early to be ranting. If I were him, I'd worry about her stepping on my face for that, since she's got no sense of humor at all about herself. But she just says that she and George should be the happy ones, and asks why they're not dancing. Insert one of a million things I've said about how dumb it was for them to even get together in the first place, and how they're not at all right for each other, here. George asks, confused, if she wants to dance, but she just blows him off and says she's going to go in early. She declares that she's going to get on Hahn's service and be kick-ass at cardio, which will piss off Cristina -- a really good reason to focus on a branch of medicine, really -- and stomps her way out the door.
