Without any surgeries on the horizon, Meredith has nothing better to do than play Dr. Phil. She finds Alex and tells him that the guy Izzie brought in is being operated on and she snuck Izzie into the gallery to watch the procedure. She will be there for awhile if Alex wants to talk to her. Alex doesn't get it. He doesn't understand Izzie and he wants Meredith to explain her to him. Meredith shakes her head, because she doesn't understand Izzie either. And she doesn't have to, because she's not married to her. Alex is not so lucky.
Back in the operating room, Cristina is done with her repair. They start the heart to check her work... and the kid is in v-fib. Cristina starts panicking and trying to figure out what she did wrong. Teddy coolly instructs her not to worry about what she did, but instead to focus on what she wants to do now to, you know, STOP THE KID FROM DYING. The clock is ticking and Arizona and Dr. Avery look nervously at both Teddy and Cristina. Cristina finally realizes that Teddy is not going to jump in, so she thinks and then decides to defibrillate. It works. Together they repair her mistake.
Alex takes a deep breath, plugs his nose, and jumps into the operating room. Izzie is ready and waiting like a shark with a chip on its shoulder. When Alex asks if she is back, Izzie attacks. She doesn't think Alex wants her back since he went to the Chief and told him she wasn't ready to be there and basically got her fired. Whatever, Izzie, you got yourself fired by almost killing a patient and costing her a spot on the transplant list. That was YOU, not Alex, not Dr. Percy, not the Chief. YOU! Nut up and own it. Also, shut it. Alex can't believe what he is hearing. He was trying to protect Izzie, but Izzie isn't hearing it. She thinks Alex interfered and got her fired. And she can't forgive him for that. Alex is fed up. He can't believe that Izzie would just make an assumption and never give him a chance to explain or deny. She just left. He can't forgive her for that. He leaves and Izzie sits prissily in her sweater (designed by Project Runway contestant Irina, obviously!) and let's Alex leave. I really want something to drop on her head right now.
The Chief watches his patient as he sleeps and recovers from the repair surgery. Bailey finds him standing there and reports that there were no complications and the repair should work. Also, no one knows. The Chief doesn't look comforted by this. He answers with a non sequitur: he's not having an affair. Bailey wants to know what it is then, because something has him distracted. Is it the merger? The budget? His unending fight with Shepherd? The Chief doesn't answer, but simply announces that he is stepping back from surgery. Bailey doesn't think that's necessary, but he does. He has too much on his plate as Chief and he can't afford another mistake. He wants Bailey to take over his surgeries. She protests, but he is firm.
