I thought someone speculated on this board that Tess was a clone of Lex's mother Lillian. I could see that making more sense than Tess being related to the family by some other way. Which is odd that it would make more sense to be a clone of a dead woman than a sister, aunt, or cousin that came from out of the blue. But hey, its Smallville. I enjoyed this week's episode BTW. Lucy is pretty hot, though not all that bright.
One thing that irked me was not using the term 'metahuman'. They went with the more frequently used term superhuman, which pertains to how Marvel describes their superheroes over DC.
