Izzie has gone back home and is packing, with open boxes all around. Wait, so she first moved into the trailer and then fled town indefinitely but she left enough at Meredith's house to need big moving boxes? That's nice of her. Mere asks if Izzie knows what it cost Meredith to make this job happen because yes, the Chief would still be running the hospital drunk and things would be just dandy if not for this. Come on, Mere. Izzie just tells her to apologize to Derek but Mere replies that it's not about that, and tells her that she can't just walk away from people and throw them away. It's a little late for that lesson, don't you think? Izzie just tells her she can't stay, she has to start over elsewhere, so Mere finally pleads, "Please don't go." She calls this Izzie's home, but as she said at lunch Izzie tells her that this is just somewhere she worked, and she can do that anywhere. Mere turns and leaves. I either mistyped her voiceover or they edited a sentence so badly that when they cut it in half they either added or forgot words so that it didn't make sense, but the gist is that against common sense, the cutting works.

"You risk exposure for the sake of healing." Very literally, (at least to Callie who doesn't know that Arizona lied) Arizona climbs into bed with Callie and when Callie protests, says she'll risk getting sick. Thankfully, someone finally thought to put some lotion on Callie's spots.

"And when it's over, once the incision has been closed, you wait." Meredith and Derek are in bed under Derek's brain diagram, lying on their backs and definitely not touching. Mere is staring at the ceiling while Derek has his eyes serenely closed, but he's definitely not sleeping as he answers Mere when she asks if he saw Richard before he left -- he didn't because he didn't think it would make it any easier. Accusingly, Meredith asks if he means easier for Richard or himself. Derek tells her that it was the best and only thing to do and that she knows it, but Mere tells him to stop pretending as it's just the two of them there, and to admit that he did it for himself. He chose surgery and ambition over love. Again, WILL NO ONE THINK OF THE CHILDREN? Well, not children, but how about him choosing the well-being of the patients and the hospital? What about the doctors that ran out of sterile supplies because Richard mismanaged things? What about that poor whipple patient if Richard had really tried to go through with the surgery? But no one brings up any of that, instead Derek just accuses her of being selfish too -- that she knew Richard wasn't ready to operate but she wanted to do the surgery so she turned a blind eye. Derek tells her that they are the same. "You wait. And you hope that your patient will heal. That you haven't, in fact, just made everything worse." She glances at him for one second, and then we're done for the week.
