Continuity mistake: During the scene where Clark and Knox fight, Knox smashes his blue container with his weapon. Shortly after this, there is a shot where he is looking in horror at what he'd done and behind him, Chloe is struggling with her ankle cuffs. She appears to be wearing shoes in this frame, whereas before and after, she is barefoot.

Trivia: Jerry Siegel, the co-creator of the Clark Kent/Superman character worked on a school magazine when he was at Glenville High School, Cleveland. The magazine was called The Torch - the same name of Smallville High's school magazine, edited by Chloe Sullivan and with Clark Kent as an on/off contributor.
