She's still in a stand-off with Derek. Cristina points out that Eric is hemorrhaging and asks if she should put in a drain, so Derek answers that it's up to Bailey. She asks Bailey and Bailey growls a, "No!" Derek then cuts off Cristina reminding him how bad things are getting and continues to stare at Bailey, then shows her his scalpel and deliberately puts it down on the tray. If overacting created energy, they would be powering all of Seattle Grace right now. Derek tells Bailey that it's her call. "Am I an executioner, or am I a surgeon?" He forgot to ask if he's also a giant blowhard, which he is. After a moment, Bailey tells him to pick up the scalpel and they get to work. Meredith watches as Bailey flees from the OR.
And after his worry that Bailey had coerced someone into donating a kidney, Richard does just that as he walks back in to the room with the grieving wife and her dead husband and announces that he can't take his liver with him to heaven. He does concede that he knows she doesn't want to think about it, but repeats that he can't take his organs with him.
The interns are all watching Mark's surgery, which just seems wrong somehow. They all are speculating about who it might be and Ryan says admiringly that whoever it was, "is going down in Seattle Grace history," given that Mark is a legend. Legend/man-ho -- Po-tay-to/Po-tah-to. Lexie finally yells at them all to shut up, that it's no one's business, which of course makes them realize she knows something. When she doesn't give up any info, they then have the idea that maybe it was Lexipedia herself. Sadie jumps in to save the day and prove that she just might be a real friend by falling on the sword (so to speak) and telling them that it was her. Lexie sneaks her a small, grateful smile.
Izzie, at her own breaking point, pulls Denny into an empty supply closet to demand to know what's up. She reminds us all that she can see, feel and even smell him and wonders if maybe he didn't actually die and that his death was just some sort of crazy bad dream. Sadly no. She asks him if he's a ghost or a dream, and again he tells her that she's a doctor and needs to think like a scientist. She yells that scientists believe what they can see and feel, and slaps him to prove she can feel that. Oh barf, then she kisses him again. She's starting to panic, and when she asks what's happening he just again says, "You tell me." She admits in a whisper that she's scared and grabs him in a bear hug. I'm scared too -- scared that this isn't going to be settled one way or another and we're going to have to not only keep seeing Denny, but keep hearing him talk in riddles.
