We finally heard fantastic news about the Finale , Michael Rosenbaum will be back for the Finale , the producers came up with a story about Lex creating clones , and one of them survived and he is rapidly aging ( fast mitoses ) and evolving into the Lex we know ( Michael Rosenbaum ) but it was comfirmed from The SMALLVILLE crew that Alexander clone is indeed Superboy , tht's a really huge turning point in the last few episodes .
So how exactly will the villain of the story return ? We don't know yet . But here are some thoughts of mine of how he actually embraces his destiny in the 22th Episode .
- The Real Lex might still be alive , after he was injured in The Arctic he cloned himself as seen in season 10 , the bleeding Lex might have been a clone all along , he was paralysed as seen in his last episode in Season 8 maybe because he cloned this decoy clone when he was still healing ... That explains him wearing a respiratory mask ( the one we saw in Season 8 Episode 14 Requiem ) and the actual Alexander managed to heal himself from the clones seen in Cadmus that would explain why the 2 functionning clones ( little Lex and old Lex ) we're locked in a room , because they weren't useful since the creator was cured !
- Alexander clone played by Lucas Grabeel in Episode 13 Season 10 " Beacon " turned out to be non other then Kon-El ( Conner Kent ) ! This clone had Clark and Luthor's DNA that would explain why Lex grew back his hair after he shaved it in Episode 6 " Harvest " . This Lex is rapidly aging each time he grows up he becomes more evil then ever since he has all of the creators memories , so maybe when he finally grows into Michael Rosenbaum all the good inside him will indeed disappear and hatred will consume him .
- The main villains in Season 10 are Darkseid & his minions , his darkness tempers on wavering souls , the rage and anger starts consuming people that way they destroy everything in their path , that might be another way to make Lex become the badass he is destined to be . And probably at the end of the finale Kent removes the darkness from Luthor ( if that was possible ) and holds the clone in his arms while he died and Lex would tell him : i'm just a failed experiment Clark " and the Clark would respond : you'r my friend ... " Changing DC COMICS' take on how their relationship goes in time , giving the show a unique plot by seeing Lex redeeming himself .
- What if there was actually a clone that never died in the Cadmus Lab fire , and was being formed at the exact age Lex was injured , he would already have anger and hatred in his heart , nothing but that , and would fit perfectly , he could actually kill Superboy the clone who turned to the good side and turned against the man who created him .
- We've seen the parallèle universe in the Episode 'Luthor' and Lex was claimed dead , but maybe , just like on Earth 1 he had his scientists work on clones to continue his journey , and maybe Clark would go there again and face off with him one last time
- The Lex in the car explosion managed to run away before the bomb triggered , or the person in that car wasn't really Lex or a clone of Lex just another person sacrificing hisself so Lex doesn't getexposed he is surviving ( that idea is a bit to amateur , I know )
