Here’s the synopsis from the CW for the next new episode of "Smallville":

Clark (Tom Welling) looks into a recent attack in a theater that may be the work of a serial killer. Suspecting it could be someone who is meteor-infected, he demands that Chloe (Allison Mack) release the names of the people she is counseling at the Isis Foundation, which causes a rift between the friends.

Davis (Sam Witwer) fears that his blackouts could mean that he is the serial killer and collects evidence that may implicate him. Fearing the worst, he confesses his suspicions to Chloe.

Erica Durance, Aaron Ashmore and Cassidy Freeman also star.

Michael Rohl directed the episode written by Brian Peterson & Kelly Souders.
