Later, in the elevator, McDreamy and Mere stand on either side of Addison, both fuming. Addie awkwardly asks if there's something going on between them, or if they had a fight. They answer in unison, "NO." Addie wants to make sure that they're all still...friends. "Still"? Mere and McDreamy, poutily: "Yes." They exit the elevator, leaving Addie in there alone with her confusion.
Cristina catches up to Burke elsewhere in the hospital and says she heard he might be getting a heart for a transplant. Burke robotically tells her that Mercy West has a heart, and he's going to get it. Cristina of course wants in. She reminds him that she's done it before, with Bailey. "You can ask her, I was very helpful." Burke cares not: he says he's sure she was helpful, but he's not going to need her on this one. Cristina ponders this rejection on her way to the ambulance bay, where a whole fleet of ambulances have arrived.
The ambulances have brought a surgical bounty of gunshot wound victims, the result of an employee who went postal and shot up a restaurant. George tells the Gang that he heard the shooter got away. Meanwhile, the hospital is filling up with the walking (and not-so-much) wounded. Bailey and Cristina's patients are an engaged couple who both got shot. The girl, Deborah, reveals that her fiancé ducked behind her during the shooting, using her as a human shield. Naturally, she's livid. The fiancé tries to make it all about love: "Deborah! The bullet went through you and into me! That's a sign we should be together forever." I'm pretty sure that's a sign Deborah should kick this guy to the curb forever, but who am I to judge? In response, Deborah shows "Neal" the hole in her arm...that she can see through. Ew. Bailey tells Cristina good luck, and takes herself far away from these people.
Callie and Meredith work on a nice-looking guy with a hipster haircut and a gunshot wound to the leg. Mere tells Callie that the guy got some morphine in the field, and he pipes up, "Ohhhh, trust me, it was not enough." Callie tells Mere to rule out other injuries and get him up to radiology. She's none too sweet about it, by the way.
George wheels in McDreamy's patient on a gurney, a young woman named Kendra Thomas. Kendra's head is all wrapped in bandages, so I'm going to assume that's where she's been shot.
