Callie sits, fidgeting over a chart and staring off into space. Mark sidles up to her and tells her that she looks like she could use some cheering up. Callie: "Not from you." She turns her back to him, but he tells her that he recalls being able to cheer her up several times in one night. She tells him it wasn't cheerful, it was dirty. Is there a difference? She tells him "no" again and walks away. Didn't Mark claim to be in love with Addison? And didn't he have sex with her just last episode? And doesn't he realize that it would be very easy for a man of his hotness to find women to sleep with who don't share his place of employment? Mark walks away, and we see that Alex was just on the other side of a pair of blinds during this entire exchange, eating an apple and looking thoughtful.
Derek is going up the Stairwell of Regrets and Recriminations when he meets Meredith coming down. She smiles and tells him, "Your sister really doesn't like me, huh?" Derek blames Nancy's bitchiness on the fact that she's from the east coast. As an easterner myself, I don't know whether to be insulted or flattered by that comment. They look at each other for long seconds. Meredith breaks the silence by starting to excuse herself, but Derek interrupts to tell her that he really should have called her after she dumped the hot vet to be with him. Meredith observes that he didn't call her. Derek: "I want us to work. It's just... it's complicated. I think I need a little time to..." Meredith: "Take some space?" She's hit the nail on the head. She's smiling as she tells him she understands, but there's that little sadness in her eyes that Ellen Pompeo is so good at conveying. The both say "okay" and walk away.
Meredith VO: "There are times when even the best of us have trouble with commitment." Just outside the front door of the hospital, Izzie is getting ready to go home. The Chief walks out behind her. He tells her that he was just looking at Meredith's evaluation of her first day back. Izzie: "I get daily report cards now?" The Chief doesn't deny it, and tells her that it was a difficult case. In some universe where all doctors are stupid and insensitive, maybe. Also, did she just handle one case her entire first day? That must be the cushiest internship ever. The Chief tells Izzie that she did a good job with Barbri. Before he walks away, he tells her, "Welcome back, Dr. Stevens." Izzie looks to be near tears.
Callie leans against a wall. She's clearly waiting for George, because when he walks off the elevator, she approaches him and apologizes for being rude to him earlier. She also tells him that she understands the whole pig metaphor and that he's now claiming to be committed. She continues, "Only we broke up. And I've been wanting to hear this from you for how long? And you wait until now to say it to me, after we've broken up?" She goes into a rant about how she is a happy, independent, single woman, but when George says "things like this, it makes it too hard." And then she winds it up: "So please, don't chase me anymore. Unless you're ready to catch me." George hasn't said a single word, and Callie walks away. And I don't see George chasing her. Mere VO: "And we may be surprised by the commitments we are willing to let slip out of our grasp."
