I watch Scrubs for the same reason I watched Star Wars: Episode III: Because I had seen the other ones. It definatley got to the point where they're just phoning in the shows, and really, I liked Elliot's boyfriend, they fitted each other. I haven't seen any of season 7, but I can probably piece it together through random speculation: JD has a kid and needs to learn how to deal with it, Elliot left Keith for JD (and, if they have time, will have to learn how to help with the little JD-ster), and at the end, someone (probably JD or the Janitor, whose name will finally be revealed) will sadly turn off a light in a room, then walk out.
Or they'll go all "Twin Peaks" on us, and JD will wake up having to go to his first day at the hospital.
