Cristina fears her streak of good surgical outcomes may come to an end if they keep performing aggressive procedures on Tyler. When things look like they are going south, she asks that her name be taken off the case. As it turns, a detached electrode only made it seem like the patient was coding. He's going to be just fine. But that doesn't stop Callie from granting her resident's request by taking her name off the case. As for Tyler, he's using his new neck to hold his head high to scream for his parents to just get a divorce already.
Cristina and Owen have been having lots and lots of sex lately. They've also been pinging each other with dirty texts until they can find a quiet little corner of the hospital to grope each other. But Owen says they can't keep doing things like that now that he's Chief. They'll have to settle for doing it at home.
Arizona and Callie will also finally get back to having sex at home once they boot Mark out the door with a slice of pizza to go. As for Derek and Meredith, they're free to have sex, too. They just can't talk about Derek's case. That's cool. Meredith already has the scoop, not that her hubby will ever know that.
