Bailey has finally decided to take on Derek in a contest for who has the most luscious wavy hair, and Derek better watch out. This must be her new peds hair -- she's putting together her application and gathering recommendation letters. All of them are glowing, except for the Chief's which is clearly a form letter. When she confronts him about it, he has a bit hissyfit that boils down to the fact that he's mad that she's not going into general surgery to take over his role one day like he had imagined. It doesn't help that he's a little bit on edge from the goings on in the hospital...

Cristina and Hunt get a patient who had a botched surgery performed by Faye Dunaway. She's an old revered surgeon that they keep locked away except for special occasions, and Cristina can't stand her since she uses old techniques and seems to not keep up. While Cristina might have been a little bit harsh about it, telling on Faye to the Chief, it turns out she's right and so Richard is going to have to fire her. At the same time he has a potential lawsuit on his hands from the woman a couple of episodes ago who came into the clinic and was told by Sadie and Izzie that she has cancer. It turns out she's only anemic, and... why, when Izzie got her own blood tests back at the same time, she thought she was only anemic too, didn't she? So Izzie sulks, yells at the interns for being inept morons, gets a mole tested out, and then gives the interns one more chance to try and correctly diagnose a mystery 29-year-old female patient. Still no official diagnosis, but we're getting closer to just finding out what's wrong, already.

Finally, Richard has to deal with Derek. He operated on poor Jen to get her speech back to normal, but he did so while fighting with Addison the whole time. She has stuck around at his request to make sure Jen's unborn child is okay, but then he only gets mad when Addie thinks he's taking too many risks and going to kill both Jen and the baby. He manages to fix whatever was affecting Jen's speech, but she and her husband only have a moment to be happy because then something goes horribly wrong for the millionth time and she's rushed back into surgery. Once in the OR, he removes one lobe of her brain, and he's going for a second when Addison points out that he's crazy and that even if she lives, Jen won't ever be the person she was before. She wants to deliver the baby but Derek forbids it, so finally Addie sends Alex running for the Chief. Once there, Richard has to basically tell Derek that it's already over for Jen, and Addison delivers the premature baby -- the only teensy consolation of this whole story being that the baby looks like he's got a good chance to live. Rob is understandably devastated, and when Derek can only repeat a bunch of times that he's sorry, Rob snaps and calls Derek a murderer. Derek goes to sulk and unfortunately, Mark picks that moment to blurt that he's been seeing Lexie. Derek turns around and punches him twice, which ticks Mark off so he punches back (and he seems to be much better at it than Derek, too, which must add insult to injury). Mere takes Derek home to heal him with tequila, and Lexie visits Mark after Callie has cleaned him up and he tells her that the beating was totally worth it for them to be public. It's one tiny happy moment in an hour that's a big old downer.
