This Friday, The CW will air the sixth episode of "Smallville's" 10th and final season. Titled "Harvest," the episode is described as follows:
Clark (Tom Welling) is concerned about Lois' (Erica Durance) safety so he diverts her away from covering the Vigilante Registrations Act by suggesting she cover another story. After he comes clean with her, an angry Lois tells him that she can take care of herself, but when a flat tire strands their car in the middle of nowhere, their plans take a turn for the worse and Lois ends up in serious danger. Meanwhile, Tess (Cassidy Freeman) searches for a cure for Alexander (guest star Connor Stanhope), who is rapidly aging. Christopher Petry directed the episode written by Al Septian & Turi Meyer.
