Again, I couldn't be happier with the repeats we're getting on MyTV if I'd picked them myself.
When I first saw this I remembering thinking how cool it was that they brought back Roy Thinnes, who'd starred in one of the first cool prime time sci-fi series himself decades before. He played this character so well.
And part 1 is when Mulder's mother and Cancer Man argue at the summer house - she has a stroke and is in the hospital - Mr. X is back! So many fascinating things.
Also the one where Mulder and Mr. X slug it out in a hospital basement/parking lot, as we were talking about earlier. I'd forgotten all about that. Mr. X says "I ought to shoot you, after all that I've given you." He has a point.
And Jeremiah Smith shape-shifts, and has that creepy conversation with Cancer Man where he turns into Deep Throat plus Mulder's dad. The latter of which really freaks out C.M., which was fun.
Oh and not to forget Chiseled Face Man (my term), the alien shape shifter.
