Back at Seattle Grace, Izzie is busily readying Denny's room for her law-breaking, boyfriend-saving maneuver. She locks the doors and shuts the blinds while Denny protests from his bed. He tells her to stop and listen to him -- they're not doing this. Izzie blithely -- and I do mean blithely, it's as if she's baking a cake, not killing her one true love -- pretends he's said nothing. "Don't worry, you're not going to die. I will be here the whole time to make sure of that, and that's what this stuff is for." Denny says it's wrong, but Izzie argues that he's waited a year and a half for this thing, and who knows when the next one will come along. Denny says he'll take his chances. I don't understand this feeling I'm having; why do I suddenly love Denny when I have hated him for so long? They start to argue much more intensely, now, Denny saying he's not about to steal a heart from another man's chest and Izzie saying he sure is. Denny finally says he's had enough, and is getting ready to call a nurse. Izzie tells him about the 17-second discrepancy between him and the other guy on the list, which is her way of rationalizing what she's doing, because obviously Denny deserves the heart just as much as the other guy. "And if you tell me any more crap about heading towards the light or looking down on me from heaven, I swear I will kill you myself right now." Denny's eyes fill with tears, and he drops his voice. "Izzie. I'm gonna be all right. You don't have to worry." Izzie isn't worried about him -- she wants to know what's going to happen to her. "What about me when you go to the light?" Here's where Izzie starts to really break down, and a lot of people have said she sucked, and overacted, but I have known this feeling of being this out of control of my life, and it is JUST LIKE THIS. So huge, huge ups to Katherine Heigl for this performance. Anyway. Izzie says she gets it, he'll be fine, but what about her? Denny just has to watch her as she gets more and more hysterical. She begs, begs him to do this for her, sobbing now. "Please do this for me. Because if you die? You have to do this for me, or I'll never be able to forgive you." Denny's crying now, too, and asks, "For dying?" Izzie screams, "No, for making me love you! Please? Please do this for me, okay? Please. Please, I can't do this, please do this for me." He takes her in his arms and says, okay, he'll do it. Izzie cries some more. Someone else you know cries, too.
