When this episode aired in Australia, Clark's dream sequence from the beginning of the next episode "Commencement", was attached to the end. This was most probably due to Network Ten's tight schedule in airing the extra-long "Commencement".
Chad Krowchuk, who plays Wendell, was Allison Mack's boyfriend in real life.
This episode marks the last appearance of the Torch until Homecoming, the 200th episode of Smallville.
In the opening shot where Chloe is signing Brandens yearbook it looks like she was nominated "Most likely to succeed". When Clark is at the Talon talking to Lois about Chloe being missing, a girl comes up and asks him to sign her yearbook, in the shot where he signs it shows that Clark was nominated "Most likely to be drafted to the NFL". When he turns the book around to show Lois a picture of who he thinks may have been the girl who didn't show up for her shift that day it can just be made out that Lana was nominated "Most likely to be a Cover Girl".
Chad Krowchuk who plays student Wendell Johnson later goes on to play the Metropolitan Internet Blogger, Glen Woodburn in Man Of Steel (2013), and Batman Vs Superman: Dawn Of Justice (2016).
