Carter is looking for Ray. "Try the roof," Chuny says. "I think he lives there." Frank corrects that Ray lives in the call room and merely cooks on the roof. How has no one noticed before now that he showers at the hospital? Oh, wait, right, they don't notice because he hasn't existed on-camera very much yet.
Upstairs on the roof, we hear the strains of a guitar (does he have an amp plugged in up there? Whatever) before we come upon Ray playing it. Brats are cooking on a charcoal grill. "What are you doing?" Carter asks. "You look all moved in up here." Ray says glibly that the rent's right and you can't beat the view. "While you're up here having a cookout, your patient has been circling the drain," Carter observes. "He's a DNR -- his daughter's bringing the paperwork from Milwaukee," Ray replies. Then he offers Carter a beer, which Carter refuses. He wanders over to the ledge and rests his hands on it, looking out at the city. "I heard about your son," Ray says. "I'm sorry." Carter thanks him without turning around. "So, you aren't really living in the hospital, are you?" he then asks Ray. Oh, please can he adopt Ray as his lost son. "Why, would that be a problem?" Ray asks. It's probably akin to squatting, but then again, this is Carter, and he doesn't care much for laws. "It might be for Weaver," Carter jokes. "She has it sprayed for interns." Ray smiles, then points out some fireworks. As Carter stares out at them, Ray starts playing the national anthem on his guitar. We push in on Carter and then fade to black on this very curious and kind of crappy episode ending.
