Yes, this story slots into canon nicely, and not just FTF.

I too prefer cynical, witty Mulder to woobified Mulder. In addition, I think this is a very sympathetically written Scully, especially considering the viewpoint is from a concussed, exhausted, and/or nauseated not-very-patient Mulder. He is surely the most unreliable narrator she's ever written, but it's easy to read between the lines. LOL.
