Watch Smallville Season 10 Episode 10 - Luthor, guest starring Glover, premieres Friday, December 3 at 8pm on The CW. For the tenth episode of Smallville's final season, fans will be treated with an Elseworlds-style story and the return of Lionel Luthor. The CW has released the synopsis for the episode now entitled Luthor
Tess (Cassidy Freeman) acquires a Kryptonian box that once belonged to Lionel Luthor (John Glover). When Clark (Tom Welling) accidentally activates the box, he's transported to a parallel universe where Lionel found Clark in the cornfields instead of the Kents. In this universe, Clark Luthor is a murderer and Lois (Erica Durance) is engaged to Oliver (Justin Hartley) and both of them hate Clark. Clark must be careful not to tip off Lionel that he's not his son while trying to figure out how to get back to Earth where the monster Clark Luthor was transported in his place. Executive producer Kelly Souders directed the episode written by Bryan Q. Miller.
We all know that Clark Luthor is a murderer and Lois is engaged to Oliver and both of them hate Clark. Clark must be careful not to tip off Lionel that he's not his son while trying to figure out how to get back to Earth where the monster Clark Luthor was transported in his place. Without tipping his hand, Clark looks for a way to get back to his own universe, where he has been replaced by his murderous double. The doppelganger episodes do get done over and over again but they get done over and over in the as well. As far as the evil Clark being called Clark, it would have been way cooler had they named him Alexander, assuming this alternate universe doesn't have a Lex Luthor as well, to see Tom Welling play a version of Lex Luthor and Clark Kent in the same episode would be pretty interesting I think. I remember someone mention this to another site I can't remember what site it is, he says how unlikely it would be that the alternate Clark would be called Clark and while I agree it would be more realistic to have him called something else this has been a feature of many an else worlds story for a long time.
