I'm laying odds that's the mother -- no spoilers that I know of, but since Scrubs has mostly ended (except for the few episodes they're going to film for ABC), Sarah Chalke is available. Also, the average life of a series is three years, so the creative team have to know time is not on their side. I don't think they imagined this as a show that would run for seven or eight years, so it would make sense that they might be starting to head toward resolutions.

And, no, you're not weird. I want it too.
