Alex and Cristina treat a young girl from Africa with heart issues. Arizona excuses herself in the middle of the first surgery because she's dealing with phantom limb pain. Owen helps her deal with this. They try a virtual reality exercise where a beach scene serves as a calming agent. She later asks Alex to stab her prosthetic foot with a scalpel when she wavers during the second surgery. Owen orders him to do this. So, Alex stabs Arizona. Calmness sets in. The OR assault did the trick. Alana witnesses the entire oddly-effective scene.
Derek's first comeback surgery with his patched-up hand (Callie claims it's her hand) is for a patient named Jimmy. The guy has been waiting for the only neurosurgeon on the planet that will touch his case to get back in the game. Derek doesn't want any distractions, so Jo deceives Alana about the operation's start time. Derek stimulates Jimmy's facial nerve often during the surgery. All is well if he twitches. Alana tries to observe, but Derek gives her the boot from his OR. A short time later, Jimmy's face stops twitching. Not good.
Now it's time for a bunch of random surgery updates. Meredith, Bailey and Shane transfer the new liver into their pregnant patient without a hitch. Mer weeps before surgery when she sees a baby pass by. Apparently, she cries when she's happy, too. The young girl from Africa is breathing easy with a fixed-up heart. Cristina loves that she got to work on such an unusual case. Finally, when Derek and Jo visit with Jimmy during his recovery, they learn that he has full use of all facial nerves. The surgery was a success. Woo hoo!
