The special effects team outdid themselves this week; the shot of Izzie slowly peeling layers of Ben's skin off are absolutely revolting. She's acting really nervous, so he tells her she's doing a good job. Because what you want is a patient reassuring a doctor. Mark then comes in and tells him he needs to ask a question and doesn't want him to be offended, but that his answer could affect his surgery. Ben gives him the okay, so he asks if Ben uses meth. Izzie's shocked and whispers, "He's like, 60!" Because old people don't ever touch controlled substances. But Ben's clean; he has no idea what meth even is, and only takes his blood pressure medication. Izzie asks what's going on and Mark explains the situation, which shocks and saddens Ben. He can't believe it at first, talking about the five years he's known them and how he watches after Brian. But finally he accepts it and sadly notes, "I baby-sit for drug dealers."
Bailey and Callie run up in time to see Clark wheeled out of the room. George explains that he coded but can't understand why; Callie mentions the meth lab situation and adds that Clark could have cardiomyopathy from his drug use. George can't believe he was able to bring him back, which surprises Callie, who can't believe he was all by himself. She asks after Meredith, and he tells her Mere's been in the clinic. She turns on Bailey to demand what she's doing there, repeating that she said to take interns. Rocking on her heels and looking very short next to an enraged Callie, Bailey says quietly, "I didn't want interns." Callie leaves, and George apologizes for her; Bailey just tells him, "Some things just don't need to be told." Even I want to cut George a break here -- he had no idea.
Meredith, meanwhile, is examining a clinic patient, and when she asks how something feels, the woman answers, "Weird." Mere's confused until the patient clarifies that the weird lady is staring at them. Of course it's Lexie. We heard about how Mere's half-sister was an amazing med student, and she came off all nice and mature in the bar with Derek last season, yet now she bumbles, fumbles, and stares at her sister instead of doing any work. The only thing consistent about these characters lately is their inconsistency. Cristina comes in to find out how the Mama Showdown went. The answer, that she's not budging and she's very scary, isn't what Cristina was hoping for. She just wants to know what Mama wants, so Mere logically (I know, Mere logical? There's more inconsistency) advises her to go get it over with. And then to come back and tell her how it went since she needs a pick-me-up, which she says while motioning to a still-staring Lexie. Cristina is indignant. "Mama Showdown is not for your enjoyment." She adds that she's going to hide in the clinic for a while, and orders Mere to make Lexie stop. "You're her sister!" Mere tells Cristina to do it: "I'm an only child! You're her resident." Cristina gathers herself up and yells, "If you have time to stare, you have time to get me coffee. Move! Move!" Lexie takes off at a sprint, and Cristina has to call to the other one, "Two! Stay!" Guess that means Lexie is #3, then. Meredith tells Cristina, "Now if you can just do that with Mama." I doubt, however, that Mama sprints for anyone.
One person not avoiding Mama is George -- he sees her waiting and excitedly heads over to sit down and visit. He happily tells her that he was "Burke's guy." He also adds that he once lived on Burke's sofa. Mama seems, rightly, amused. When George asks how Burke is doing, she replies, "He's Preston! He's a gentleman! And so he doesn't like to talk about it. And I just really don't know what to say to him." George suggests telling him he dodged a bullet. He then adds, "Once you're in, you're in." He calls Burke smart for not making a mistake that's hard to take back. He's of the camp that thinks no other human can pick up on ginormously obvious cues, but Mama dryly observes, "'Once you're in, you're in.' Be sure to have that engraved on your wedding ring when you get married." Not picking up on any sort of tone, he conversationally tells her he's already married. George, are you a moron? She's surprised to hear he's married, romantic as he sounds, and tells him that staying in a marriage out of obligation is no way to live and love. She also thinks he knows that. That might be giving him a bit too much credit, there. He says he does, then amends that: "Sometimes I do."
