A pretty woman in scrubs stops Derek and tells him she's sorry about what happened to Danny, since she noticed it seemed to be hard on him. She then babbles, because that's what the women do here, about how it's not good, but if she had a son she'd want her surgeon to be invested in him. Derek is grateful but confused, and she realizes he has no idea who she is (and neither do we). He tries to fake it, and she turns and leaves. He calls after her that she was the nurse in the OR who talked about cliques, and she just turns and smiles.
Patricia is awake and freaking out that she'll never be captain again. Callie tries to help her out by telling her she was recently fired -- prompting a freak-out: "You were fired from being a doctor and they let you cut open my ass?" Callie orders her, "Okay, shut your trap for eight seconds and let me finish." She explains that she was fired from their version of being a captain, which was more about organizing than surgery, but it meant she got to go back to the part of the job she liked, which she calls a gift of sorts. Patricia gives her a wee smile and mercifully keeps her mouth shut.
Cristina is still in the lounge when her pager goes off, and she jumps up and exclaims that it's Hahn. She grabs for the door, then stops and composes herself, then half-walks, half-runs, trying unsuccessfully to be cool, down the hall. In the OR, Hahn mentions not being given everything she needed, and asks Cristina to get her the CT as Bailey looks on. Cristina manages to be mostly cool as she agrees and turns to go, but once outside, she grins and heaves a breath.
Mere drops off some papers where Lexie is working at the nurses' station, and comments that their dad was in the OR. Lexie tells her she knows, so Mere asks if Lexie knew he was drunk and put his hand through a window. Lex asks if there's anything else, so Meredith says she knows it was Susan's birthday and that it was a hard day for both of them -- Lexie with her head to one side, pissed off -- and Mere says he wasn't a problem and was actually charming, but he seemed sad, she'd hate for it to happen again. She then has the absolute gall to tell Lexie that she should keep a better eye on him. Let's pause a moment to think about this. Whether she knew or not about the birthday or whatever, if she's spent so much time reminding Lexie that he's her real father and not Meredith's, don't you think she should then stay out of the business of Lexie and Thatcher's relationship? But the compliments clearly went to her head. Lexie guesses that too, and has had it: "Every day is my mother's birthday. My mother was born in March." She tells Mere that he's a liar, and angrily snarks that she's glad Meredith found him charming, saying that after five drinks he's great, but after nine, not so much. Richard comes up behind them and overhears as Lexie goes on to guess that Thatcher came in and told Mere how wonderful she is and how proud he is of her. She says that one day he'll tell Lexie she's his favorite, and the next that she's an ungrateful bitch. One time he wrote her a check for $20,000 because he said she deserved it and he was so proud of her. "A lifetime's worth of proud." This is finally when Mere's face goes from condescendingly sad to realization. Lexie spits, "So, thank you, for letting me know I need to keep a better eye on him. Thanks," and then storms away. Richard walks up to Mere where she's hyperventilating against the wall, and asks her to come in and sit down for a minute.
