It's another semi-montage. In Nurse Fallon's room, a huge crowd of nurses and doctors has gathered to witness her passing. The monitor flatlines, and Burke listens for a heartbeat. Cristina still looks abashed, and Burke asks her if she's ever called a time of death. She hasn't. The Chief tells her to call it. Cristina announces the time of death as 11:43 and walks out of the room.

We see McDreamy speaking to Mrs. Jorge while Mere watches. Mrs. Jorge walks away from McDreamy and gives Mere an inscrutable look as she passes on the way back to Jorge's room. Mere's voiceover tells us, "I wish there were a rulebook for intimacy. Some kind of a guide that could tell you when you've crossed the line." McDreamy walks over to Mere, but she just walks away.

Mere's VO continues: "It would be nice if you could see it coming. But I don't know how you'd fit it on a map." Burke walks into the stairwell and finds Cristina. He says something indeterminate, and she responds with an angry gesture. She starts to walk away (I think to do something in Nurse Fallon's room), and he grabs her and whispers, "Let her go. We have to let her go." Cristina looks to be on the verge of tears, and these two look to be on the verge of making out. "Crossing the line," indeed.

CM is wheeled out of the O.R. In the scrub room, Bailey tells Izzie, "Of course, now you know, every time he gets a rise, he'll be thinking of you." Izzie smiles.

Mere's VO: "You take it where you can get it. And keep it as long as you can." We see Jorge, still pre-surgery, taking a photo of his wife in her red dress. Then we cut to Mere slowly walking down a flight of stairs with her mother. Mere's VO: "And as for rules? Maybe there are none." Cut to George, getting out of the shower to find Izzie brushing her teeth. He tells her that she'd better not be using his toothbrush, and she confirms that she's not. Because she's not a pig.

Mere's VO: "Maybe the rules of intimacy are something you have to define for yourself." Cut to Mere walking onto the patio of a restaurant and sitting down for breakfast with McDreamy. Credits.
