Clark Luthor uses his Kryptonian mirror box to zap himself into Clark Kent's universe. Luthor tricks Clark into zapping himself into the other universe by just leaving the mirror box on a table and waiting for Clark to use it. It's a simple plan, but why waste good cheese in the trap when you know the rat can't tell the difference? Luthor then proceeds to flirt with Lois for a bit, but gives himself away when he slanders Clark's telescope. Either he doesn't realize she knows or he's too busy to kill her right off. He's eager to hook up with Tess, who also almost immediately recognizes that this sexually-charged piece of man isn't the Clark she knows. He drops the charade. He wants nothing more than to play house with sister Tess, as long as she tells him where to find Lionel. Tess is tempted, but refuses to let Luthor kill Lionel, which pleases her sexy bro not at all. Luckily, Emil has kept pieces of Clark's broken mirror box and is frantically working to restore it so that they can get him back.
Meanwhile, Clark finds himself in the other universe at the burial of Oliver Queen, dead by Ultraman's hand. He quickly convinces Lois Queen that he's the good version she met last time, but the rest of the city is against him, having been armed by Oliver with chunks of kryptonite. A drunken Jonathan Kent crashes the funeral, railing about the "rich brat" who stole his farm. Clark seeks him out at the farm, only to find himself Jonathan's prisoner. After a k-tinged walloping, he convinces Jonathan that he's not Clark Luthor. Before they can exchange hugs, Clark is zapped back to his own universe by the newly restored mirror box. He has a brief fight with his Luthor self that concludes in the Fortress, where Clark tells Luthor that it's not too late to be a hero, then uses some kind of Krypto-Mojo to restore him to his proper reality. Now in his own Fortress, Clark Luthor meets Jor-El for the first time and suddenly everything is all kittens and rainbows.
In the subplot, Martha has deeded the farm to Clark and Lois. They waffle about what to do with it, but eventually decide to sell it and move into an apartment in the city. If Shelby is still alive, he is going to be pissed.
We watched the pilot again last week, and it made us miss the simpler times… when there was only one quaint little universe.
