Lenny von Dohlen who plays Jason Brassell in this episode also plays Harold Smith in Twin Peaks (1990), which the title of the episode references.
Pollux has characteristics of two DC comics villains. The first is Superman's foil Bizarro. Both are clones of the hero created by villains for evil purposes, yet are ignorant and childish rather than willfully malicious, and the hero comes to feel sympathy for them. The other villain is Flash's enemy, Reverse Flash. Both characters have an inverse or reverse version of the other's costume (Reverse Flash switches red for yellow in his costume while Pollux/Flash switches blue for red and silver for gold). Also, the sound effect for Pollux Flash's super speed is the sound effect for Flash's played backwards.
