Back in the girls' surgery, Jackson and Arizona are figuring out their next step but every time Jackson makes an observation or suggestion, Arizona jumps down his throat and proceeds to cut off anything he tries to say before announcing that they'll do this procedure her way. Callie raises her eyebrows at her wife but seems to know better than to jump in to the fray. It's now time for the flip, and Owen reminds everyone that they can't repeat the disaster from earlier. Alex goes to Owen and tells him quietly that he wanted to talk to him about just that -- that their practices had all been fine but today Arizona doesn't trust anyone and is making everyone uncomfortable. Owen asks him to get to the point and Alex says he doesn't want to screw up the procedure and that they have to be a perfect team. Richard is watching this exchange from afar and it plays out just as he intended: when Alex agrees with Owen that he doesn't want to do the flip with Arizona, Owen calls out to the room to find a replacement for Alex and Richard immediately offers his services. Alex is left stewing that his plan just blew up rather spectacularly in his face.
As Richard goes over the procedure with Arizona, Alex glowers at them. Lexie comes in and when she finds out what happened, she starts to freak out since she just promised the nervous parents that the flippers had been practicing for weeks. As she watches nervously, Alex gripes that he hopes that Richard drops the babies. Lexie is aghast and Alex quickly admits he's just mad, but Lexie thinks what he said was way over the line. Of course, the flip goes perfectly and all of the doctors minus Alex applaud the good job.
Cristina finishes up yet another macabre recitation and Teddy asks her about the tumor, grilling her about how she could possibly be sure it had eroded Henry's pulmonary artery if she didn't actually see it. Cristina seems frustrated for the first time as she explains her entire thought process and then defends that she really was totally sure of what had happened. After a moment, Teddy tells her to start again from the beginning, and Cristina has to take a deep breath and gather herself for a moment before starting over. Teddy again closes her eyes and visualizes the surgery as Cristina repeats it -- thank goodness April is there to keep an eye on the actual patient in front of them, but she looks like she'd really rather be any place in the world other than here, witnessing this rather tragic spectacle.
