Willie Garson, who plays Weems, was previously the janitor in The Walk, a rare case of character-actor recycling for The X-Files. I like this episode, but I could have gone for even more improbable Rube Goldbergian strings of cause and effect. There’s a story in the Tenchi Muyo manga that uses a similar concept really cleverly, and brother, when the Tenchi Muyo manga has smarter writing than your thing, you’re in trouble.
