As regards the above discussion: I always see M/O as an interesting complication on the way to the inevitable MSR. And--perhaps projecting my own prejudice--I think Mulder contemplating a hookup with Melinda is a way of him evading or escaping the unadmitted yearning for Scully. A bit unfair to the OC, but that's how I roll.

And then she gets killed. Overkilled, when you look at it that way. Geez.
