We try to remember an episode about Clark trying to remember this week as Tom Welling and Michael Rosenbaum revisit Smallville Season 4 Episode 19: BLANK! After we explore Jensenās character diving off the deep end, the guys explore Chloeās character development and how itās grown since Season 1. We also continue the rage against yellow vehicles and try to figure out what the motivation for the evil Dick Cheney-like father was in this episode.
