Smallville teaches us that even parallel universe dads need marriage counselingCyriaque Lamar4/16/11 2:45pmFiled to: Tv recapsmallvilleTopTelevisionSuperman241EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkYesterday's episode of Smallville, "Kent," marked the return of Clark's evil alternate universe doppelganger, Clark "Ultraman" Luthor. Despite being one of the last episodes of Smallville ever, not a lot of consequence happened here, but there was some hefty foreshadowing.AdvertisementSpoilers from here on out...After a month-plus hiatus, Smallville has returned for the last time. Counting the two-hour series finale, we have four more episodes left. Given this limited time frame, you'd think the show would flesh out any number of dangling subplots (alternate universe Lionel's deal with Darkseid, Oliver succumbing to the darkness, and so on).Instead "Kent" revisited Smallville's Earth 2, where Clark was adopted by Lionel Luthor, grew up to be a complete tool, and fools around with his (non-biologically related) sister. The last time we saw Earth 2 was in December's episode "Luthor."
