Having dispensed of the interns, Bailey goes inside and shuts the door. Meredith is spurred into motion and goes into her locker as Bailey asks her if she's okay to work, adding that she'd understand if Mere needs to be with her mother. Meredith opens up as much as she can to say, "No. My mother and I don't have the easiest...it's just better, if I'm working." When Bailey gives her scut, she's super-pissed, and unconvincingly tells Bailey that she's fine. Bailey gets firm and answers, "And I appreciate that you're fine, but I have to anticipate a certain level of distraction from you, even in the face of all that fineness. So scut, now."
In the NICU, Izzie touches a tiny baby in an incubator. The mom has fled and the baby is on drugs, which agitates Derek. I mean, that should enrage anyone, but he's especially pissed by this situation. Addison interrupts him to say she knows it's a long shot; it appears that she's asked him to perform a procedure on the baby. She neglected to mention that the baby was premature, underweight, and addicted to drugs. He's convinced the baby won't survive spinal surgery, and no matter how many times she tries to tell him he doesn't know that for sure, he counters her. She finally tells him that he's not God. "I'm sorry, honey, but you're not." As soon as it's out of her mouth they're both on alert, and Derek angrily asks to make sure he really heard the word "honey" come out of her mouth. She apologizes and tells him, "You're not God, Dr. Shepherd." She then tells him that if the baby is to have any chance of survival it's his responsibility to do this, which seems to be another hot button, and he yelps that she's not to talk to him about responsibility. It dissolves into an argument about her sleeping with his best friend, and her messing up but trying to make it right, et cetera. Then it further deteriorates into arguing about how the deed was done on Derek's favorite sheets. Izzie is still there having witnessed all of this, looking like she wants to die. She clears her throat and makes a getaway to check the lab results. Derek tells Addie not to get too attached, even though she argues that the baby is a fighter. Derek: "Don't make your life more painful than it already is." One might argue that you're doing that to her, Derek: even if this is going to result in divorce, you could try being mature about it. But I guess that's not good TV. He tells Addie that the baby's too far gone and she should let her go in peace. Addie retorts, "Fine, Derek, walk away. It's what you do best." And to the woman who cheated on her husband I also suggest, let's try maturity. You did make a rather large boo-boo. These two are such a headache.
