Simultaneously, Tucker's still crashing as Bailey's still pushing. Addie orders Bailey to stop pushing and George peers into the mirror behind Addie's head and tells Bailey that he can see the top of the baby's head and that it has lots of hair and is cute. "O'Malley?" Bailey gasps. "Stop lookin' at mah va-jay-jay!" HA HA HA HA. Oh, god. It's not just the word that's funny. It's Chandra Wilson's delivery. It's like quiet on the first syllable and then explosively pissed off in the second two. Genius. Adding to the funny is T.R. Knight's expression as he pointedly looks far, far away from the va-jay-jay and says, "Yes, ma'am." Heeeeee.
Stop laughing -- Tucker's still crashing. McDreamy goes into hero mode and leaps around the table and starts delivering the chest pumps himself. Still nothing. Cristina looks at him in alarm. Bailey pushes. Tucker crashes. McDreamy pulls back from the table in defeat. Then he hauls off and throws all his weight into a punch to Tucker's chest. We switch to Mere, who's finally pulled the bomb out of the chest and is slowly handing it to Hot Kyle. Back with Tucker, McDreamy's shot to the heart (and you're to blame!) apparently has magical healing powers because suddenly, Tucker's alive again and all is right with the world. Hot Kyle has the bomb now, by the way, and he looks at Mere and tells her that she did good. Aw. He slowly turns and walks out of the room as Mere steps back to let Burke get to work.
Mere's breathing heavily as she watches Kyle walk away. Suddenly, she decides to go after him, maybe to tell him thank you or to give him her number or something, but before she can say, "I love you, Hot Kyle!" the bomb blows up and so does Hot Kyle and Mere gets thrown back through the air and lands on her head as Hot Kyle's Pink Mist floats down around her. The hallway fills with smoke and flaming papers and dust and ash and debris and man, even though I saw that one coming, I still jumped right out of my skin when it happened. Poor Hot Kyle.
The rest of the hospital must have heard the explosion because when we come back from the commercials, the Chief is on the phone demanding to know what the hell is happening down in his OR. "Who's coming up?" he asks. "Okay." He gets off the phone and yells at everyone that "they're" coming up, only we don't know who "they" are. The camera swoops along at floor level toward the elevators as the Chief and Mrs. Chief and the entire Seattle population, apparently, go to meet whoever it is who's arriving. The elevator doors open up and we see Burke and McDreamy leaning against the back, utterly exhausted. They look out and seem surprised to find a welcome wagon staring back at them. They walk out, and Burke throws a look at McDreamy. "Derek," he says with a smirk. "Preston," volleys McDreamy. Heh. Aw. They're friends now!
