Arizona assures them that Zola is being cared for by a team of nurses who are making sure she's well taken care of and not alone at any second. Derek yells that he should be the one to fix the shunt but Alex finally pipes up to remind them that Janet is hanging out and just waiting for something like that to happen. But Derek knows that Alex is also feeling guilty about the whole situation and eventually bullies him into admitting where Zola is, so Derek starts to run off with the whole gang of doctors trailing him. Meredith is ultimately the one who calms him down -- she explains that Zola is here now because the foster parents didn't know what to look for when she started having symptoms, and takes full responsibility for that. She begs him to understand that while she has to live with that, they now need to mind their p's and q's. She also reminds him that Arizona is a great surgeon, and so grudgingly Derek asks her what she will do. She explains how she'll fix the obstruction and if need be, will fix the shunt as well. Derek paces while he thinks.
He seems to have agreed since we next see him in the stairwell. Owen joins him and tells him that they are starting the surgery, then sits down on the step just down from him. Much like the male hug/back-clap, this is a way for him to show he's there to talk but not going to sit too close. Derek admits that he knows he should be with Meredith since he can see that she is in pain too, but he can barely look at her because he still considers this entirely her fault. Yes, and he's been nothing but the picture of perfection through this entire ordeal. Gah! Sorry, I've said my peace, and I'm going to try and make it through the rest of this episode calmly and gracefully, like Catherine Avery would like. Derek adds that every time he thinks he's forgiven Meredith something happens that puts him right back at the beginning of all his anger. Owen tells him that he and Cristina just went through something difficult too, so he knows how he feels. He adds that the girls don't make it easy for them, and Derek chuckles while both of them furrow their brows deeply over their difficult, maddening wives.
