Lexie walks up to Alex but he tells her not to talk to him here since Sloan has crazy eyes. Lexie brushes this off and asks if she is still Mark's property, but when she offers to talk to him Alex tells her to wait since they are going to be in surgery together soon. She looks across the room at Mark and then gives a big "Ugh," and goes to sit with Mere and Cristina. She complains about Mark wanting to kill Alex but when Mere tries to remind her that sleeping with Alex is a bad idea Lexie insists that the situation is happy and easy, and that Mark took so much mental energy that this is the best thing that could have happened to her. Cristina clearly doesn't believe all this but Lexie goes so far as to talk about how much happier Mark would be if he could just move on. Mere decides to test this and says he was picking up Teddy, but Lexie is convinced that's just for sex like all of the other drug reps and nurses, and complains about his double standard for her sex life. Cristina just mocks her, telling her that there's no getting over her, so she lets out another "Ugh," and leaves. Mere laughs at Cristina and her ability to clear a room when Hunt joins them to tell Mere that Audrey's new scans are ready. Cristina asks how it's going and they give her an update, but when Mere asks about Richard's plans she gets all vague and says that he's flailing like the sad, old guy he is. She's made the classic mistake of going too far with her lie, because Hunt knows Richard isn't a flailer. Cristina leaves to go help him some more and Mere and Hunt know that she's been turned and run to go get to the scans before she does.
Derek finds Bailey in street clothes and asks her to come help with a consult, and he's incredibly surprised when she says no, pointing out that he's never seen her eat in all the time he's known her. Come to think of it, I think he might be right as I can't remember ever seeing her in the cafeteria or eating elsewhere. How very meta. She gets all combative as she defends that she has things to do and finally tells Derek that this doesn't require an interrogation, demanding to know if that's the kind of Chief -- nay, the kind of MAN -- he wants to be? He's frightened and confused, having received a good, old-fashioned Bailey smackdown, and she pushes out the door.
