Owen is sleeping in an on-call room when Cristina quietly sneaks in and watches him a moment. He's confused to see her but sits up and tries to sound supportive as he asks her where she's going to go. She sits down next to him, he adds that she can't go wrong with any of her choices. When she finally turns to look at him he's staring sadly at the wall and when he turns to her, she then kisses him. He's confused and kind of scared but she touches his face and after that, they start kissing desperately and climb into bed, grabbing at each other as if their lives depended on it.
Ben is at home on the sofa when Bailey gets home, and she walks in wearing her hair up, makeup, heels, and a black trench coat. She strikes a pose, and asks Ben to propose to her again. He looks at her, obviously liking what he sees, but tells her that she should come sit down with him. NO. That is never good and I don't like it because I like these two together. She undoes her coat and flashes him with whatever might or might not be underneath and repeats her request, but he tells her that while he'd love nothing more than that she should sit down. She thinks he's upset about the botched proposal and gets exasperated but tells him she's wearing a thong now, which is as sorry as she gets. "Ask me!" Instead, he reminds her that there was the shooting, and they broke up, and that he wanted to go do something inspiring but didn't think whatever it was would actually happen. Oh lord, didn't we hear this almost verbatim once from Arizona? Sure enough, he admits that he was accepted at UCLA (Go Bruins!) as a surgical intern. She stares, shocked, and he reminds her that this means he'd be working seven days a week, crazy hours, 1,000 miles away. As she finally sits down he tells her, "Everything's different now." Look, this is a bloated cast, but he wasn't on the list of people I wanted to leave.
Cristina and Owen are lying together in post-coital quiet, and he gazes at her and admits that at this moment, he is actually happy. He admits that he knows it doesn't fix anything, but he's happy as he lies there stroking her hair. I also think (and come on, yes, it's from experience) that he may know intellectually that this doesn't change anything but that he's hoping desperately -- even if it's subconscious -- that this actually does change things. But it really doesn't, because Cristina's face goes from contented and happy to sad and she tells him quietly that she's leaving. She looks away while he stares at the ceiling, looking as if the wind has just been knocked out of him.
