Derek watches Meredith through a window and asks Mark if he was actually happy when they were together. Mark tells him it was off and on, which prompts Derek to announce that he thinks that he idealized it, and supposes Mark wouldn't stay with someone so unpredictable and unavailable. He reiterates his whole idea of keeping things light and casual. Here's another one -- fucking woe is me, Derek! You knew what you were getting into when you got back together with her for the forty-seventh time, so you can't have some epiphany about it now! Mark tells him not to sell himself short with Rose and advises that he grow and share experiences with her. It's that new leaf talking.
George is finishing the line and Tapley compliments his work, referring to him as a resident. George says that he's an intern, but Lexie adoringly adds that he's the best intern in the hospital. Richard pops his head in and orders George to give Tapley some specific meds, to which Tapley takes exception. Richard sends George out so that he can have a private talk with Tapley. Tapley announces, "If you can't get the head of cardiothorasics to do a valve replacement, then you're not the Chief I thought you were. And this is not the facility I thought it was, so maybe it's better for all of us if I don't get cut open here." I'll wager a guess that it really isn't what he thought it was, because I don't think this guy would stand for a resident spending her time making paperclip sculptures and demoralizing her interns while shunning actual work. He gets up and tries to disentangle himself from his various tubes until Richard demands that he get back in bed. A bit less forcefully, he promises to talk to Hahn again.
Cristina and Meredith are in the cafeteria, Cristina sucking on a soda and staring blankly into space while Meredith reads a magazine. She casually looks up and asks Cristina if she's even going to watch Tapley's surgery, but Cristina informs her that she wants five years with him, not five minutes. "Tapley's a star-maker. That's why the Chief's a star. Five minutes with Tapley is a slap in the face. Like giving an alcoholic a sip of wine." Lexie comes in and Mere cautions Cristina to try and watch what she says. Lexie asks Mere if they can speak alone, and motions her eyes toward Cristina. Mere says now's not good, and does her own eye-point to her friend. Cristina sits up and informs Lexie that Meredith hates her and finds her annoying. She says Lexie's showing up is the worst thing that's happened to her in months, "And that's saying a lot coming from Meredith Grey." Mere looks stunned but yet can't bring herself to say anything, and Lexie just takes off like she's been slapped. Mere eats a chip and tells Cristina that it will be okay but Cristina snaps, "Wanna bet?"
