Danny hits the bone and starts to freak out again, while Callie assures him that that is a good thing. She then instructs him to take a clamp and work it back and forth underneath the bone. He struggles and can't really get it, which is frustrating, but when Callie tells him to put his hand in the incision to get some traction, it causes the last bit of courage that was holding him together to melt away. Quite understandably, I might add. He begins to scream that he's going to kill his wife and he can't do this, and Owen has seen enough. He declares he's going down there and while Karen protests, it's pretty weak sauce and Owen pretty much ignores her. Callie tries to convince him that Danny can do it but Owen says that they are asking too much of the poor guy. Callie points out that she should probably be the one to go but since she has a wife and baby, that outweighs his just having an estranged wife so he does the job.
Meredith has finally removed herself from the vicinity of patients and is watching her daughter in daycare through the window. Cristina comes up, responding to a page, and Mere announces that she has a plan: to just be a mom. Cristina thinks it's a joke but Mere is serious, even though she's still such a damaged person that she doesn't know the saying, "Blessing in disguise," and Cristina has to provide it for her. (Her voice is dripping with disdain as she says the words.) The kooky music starts up so we know for sure that the idea of Meredith driving carpool is hilaaarious. Cristina excuses herself to vomit and go back to work, but Mere calls after her that maybe Cristina wants to be a mom too and that's why she can't go through with the abortion. That's a pretty low blow on Mere's part, since we all know Cristina so well at this point to know that she sticks to her guns. We didn't need the music to turn suddenly somber to really hammer us over the head with the point, Show. Cristina earnestly tells Meredith that she wishes she wanted the baby because that would make everything easy and she'd be happy. But she doesn't want a child and doesn't want to be a mother, just a surgeon. She sincerely asks Meredith to understand because Owen doesn't and that's ripping Cristina apart. She needs someone to understand and that person should be Mere, since she is her Person. No matter how stupid the writers make these women act sometimes, I appreciate that they have always kept the thread of how these two are even closer than sisters; they are really all each other has. She tells Meredith that she is sad and scared, and needs Mere to be there with her through the procedure to hold her hand. Mere now looks like she's the one who is going to vomit.
