At the hospital, clearly late, Burke sits reviewing the file. Meredith is heading home, emotionally and physically drained, and arrives to thumping music, taxis letting off partiers, and a pulsing crowd spilling out of her house. She mutters, "Izzie, I'm gonna kill you..." Inside, Cristina looks awesome in an off-the-shoulder sweater -- that is, until she turns around and I realize that it's a cardigan on backwards. It's like some strange homage to Kris Kross, but fifteen years or so too late. I wish I hadn't seen that and could go back to admiring her sexy party top. She goes for the food but Bailey appears, saying, "You could touch that, but I'd have to kill you." She's rocking a purple top with a satin shawl on one shoulder, and some big, sexy, party hair. While she peruses the food, Cristina tries to ask about the towel but gets shut down. Bailey will only tell her, "It's been taken care of." After more questioning, she finally orders, "We're not going to talk about it is what's going to happen. We clear, or have you had too much alcohol to understand me?" Chastised, Cristina agrees that she's very clear. That out of the way, Bailey grabs a plastic cup and looks for the bourbon. Cristina walks away and the room is filled with absolutely no one else we've ever seen before.

Jerry's not taking the leaving very well and is begging for Demerol and physically trying to stop the forward motion of the wheelchair in which he's riding. As he gets more and more agitated, Izzie goes to call psych. Before she can make the call, he gets up to run away but trips and falls, cracking his head on what seems to be a portable x-ray machine. Izzie and Alex page McDreamy and they do a CT that shows subdural bleed with midline shift. I had no idea until this very moment that the midline of your brain could shift -- I think mine is shifting just trying to figure out the physics of that -- but it definitely seems bad and they have to do surgery immediately. McDreamy asks, "Anywhere else you need to be, Dr. Stevens, or are you in?" A wide-eyed Izzie asks, "Brain surgery? Are you kidding me?" McDreamy happily replies, "That's what I thought."

Meredith drags herself into her pulsating house, rescuing furniture along the way. Holding a Tiffany-looking lamp, she finds George and demands to see Izzie, understandably freaking out about the huge party. George tries to escape but when Meredith begins to sound desperate about not being able to handle things, he puffs up and offers to kick everyone out. Right at that moment, however, a very drunk and elated Cristina looks over and yells, "Baby, you made it!" She throws her arms up and it only takes Meredith a second to change her mind. "Screw it! Hold this," (shoves the lamp into George's arms) "and give me this," (tequila.) She jumps onto the coffee table with Cristina, dances, and chugs. It's not the size bottle that actually needs a handle, but it's the one just beneath that, and she does a very impressive job with the swig she takes. They plead with George to join them, and he finally gets up, chugs (though he's clearly an amateur and chokes a little bit) and they make a George sandwich and dance and dance.
