Izzie brings Alex some juice to help his fever but he turns it down, so she pushes him about being run down, which turns into her admonishing that Ava can't just move in yet and that they have to take it slower. Alex demands to know what her problem is, as she loves every other baby she's ever seen. She tells him that it's not him but when he demands to know what it is, she takes a deep breath and says it's nothing. He storms off and she chews on her cheek and sulks.
Hahn is scrubbing in when Callie joins her, and Hahn asks if they're on for drinks. Callie reminds Hahn about her "thing," and Hahn just nods her head a while before telling Callie she doesn't make friends easily and admits her faults -- she's awkward, bad at small talk, and usually doesn't like people she doesn't know, exhibiting these faults as she says it. She takes a moment and says that she made friends with Callie but now Callie has a "thing" called Sloane. When Callie asks, she says she isn't mad that she's sleeping with Sloane, she's just upset that Callie didn't tell her. She says Callie is one of those girls who turns into a flaky airhead when she gets a guy. Hahn storms off but before walking into the ER repeats that she doesn't make friends easily. Callie's shoulders slump as she watches her go.
A gorgeous nighttime shot of the city lets us know that time has passed. Derek and Meredith are out of surgery and she's giddy that they were in sync and things seemed to work. After the little congratulatory celebration Meredith says she'll stay and monitor him overnight, but Derek jumps in immediately to tell her that he'll stay too, adding, "We can stay together." After that schlocky line, it's only fitting that Rose should show up and ask how it went, because remember? He's dating someone else and has conflicting feelings as he gets closer to his ex who clearly still loves him. He's all stilted and nervous as he tells her, and she then awkwardly asks if he wants to go with her. Derek tells her he has to stay but as she walks away, Meredith takes a deep breath and calls after her on his behalf. He's all flustered by the change in events, and breathily tells her that if she asks him to stay, he'll stay. But she merely smiles at him and tells him he should be with Rose.
