The doctors are with a patient. Her name is "Kimberly Griswold," and she's there for another of multiple heart surgeries. Mrs. Griswold is blithely applying her makeup as this goes on. Her husband stands by and assists her with mirrors and whatnot. Alex runs in, and Izzie tells him through clenched teeth, "You're late." Burke adds, "Yes, Karev, nice of you to join us." Uh-oh. Alex in big trouble. Burke turns to Cristina. "Why keep the heart beating, Dr. Yang?" Cristina, who obviously knows the answer, gives him a blank look. "I don't...know?" Zany music starts to play. Bailey's astounded, all, "What?!?" Cristina repeats, "I have no idea." Izzie chimes in, "Oh, I don't know either." Dumb Meredith starts to answer until Izzie pinches the shit out of her. "OW! Ohhhh." Burke asks if anyone knows the answer. Alex starts to say it, but Burke cuts him off and asks George, who answers correctly. Alex sulks. You have to wake up early in the morning to beat George! George gets the case, and Cristina and Izzie tell Mere it's time to go.
Outside the room, Alex complains to Bailey that Burke is punishing him for the elevator incident. I wish I had a recap to link back to for that, but alas. The world is harsh. Bailey tells Alex that he was punishing him because he was late. Alex can offer no explanation as to why he was late, and Bailey just shakes her head. She tells him she needs somebody on a "nerve case," and unfortunately she is not referring to herself. Alex goes. Bailey turns to the three giggling stooges standing behind her. "And YOU THREE. Brush up on how not to embarrass me in front of the attendings, or I'll see to it that your hearts stop beating. We clear?" All three of them mumble insincere apologies, and run off to their little adventure.
