The team is tasked with an 18-hour surgery to save conjoined twins. Our favorite docs will perform tag team procedures throughout the day. Everyone has been practicing for weeks. Arizona has been caring for these babies since they were born. That's why she's completely amped up during yet another practice surgery to make sure everything goes right come show time.
Richard gets in Alex's head by suggesting that Arizona's overzealousness may cause problems when he's up to bat with the twins. He totally manipulates his unsuspecting prey to the point where Richard gets to jump in to do Alex's part of the operation. Needless to say, Alex is not happy.
There's a bit of a scare during the spinal cord procedure when one of the twins does not initially respond to stimulation. After a few tense moments, the young baby finally moves her foot. There are cheers all around, but they still have a long way to go. Things take a bad turn when one baby's kidney starts failing. Alex suggests they do a transplant with the other twin. Since it was his idea, he gets to do the procedure. Woo hoo!
Richard apologizes to Alex as he scrubs in. He says he's getting older. This was probably his last chance to get in on such a rare procedure. Alex feels bad for the former chief. He offers to let him do the kidney transplant, too. It's a nice gesture. Alex should feel good, right? Wrong. Richard totally played him again. Alex learns a tough lesson. You never ever give up once-in-a-lifetime surgeries.
