When Clark uses his X-ray vison on Victor his face lookes like the comic Cyborg
During filming of this episode, Tom Welling fell ill for the first time in five years and production was halted for four days while he recovered.
Mackenzie Gray would later go on to play the Kryptonian "Jax-Ur" in Zack Snyder's Man of Steel (2013)
It is revealed in this episode that Lionel knows that Clark's Kryptonian birthname is "Kal-El". However, it is not clear if he obtained this knowledge through his work with Veritas's "Traveler" theory, or if he learned it while functioning as an emissary for Jor-El.
Victor Stone is Smallville's version of DC Comics character Cyborg. Cyborg first appeared in DC Comics Presents #26 (Oct. 1980) as a young man whose parents were experimenting with portals to different dimensions. A creature was released that killed his mother and badly injured Victor. His father rebuilt his son's body with bionic parts, but Victor harbored deep resentment for his father and left to join the superhero group Teen Titans. Victor's bionic enhancements are both endo- and exoskeletal, but his outward appearance in Smallville is normal. However, Clark's X-ray view of his metal skull plate is similar to what Cyborg's head looks like in the comics. Unlike on the show, in the comics, Victor Stone goes by "Vic."
