Chloe says that going psycho isn't the only thing she has to worry about. She tells Clark that when she healed Lois in the dam, it almost killed her. Clark asks what the side effects are of the procedure. Chloe says it's just a little memory loss. She says it's worth giving up a little bit of her past to have a future. Clark says she'll forget her friends and her experiences. He has a realization. "You're gonna forget me," he says, genuinely hurt. He repeats it because he's just that sad. Chloe, almost teary, says her friends will be there to fill in the blanks, and that in time, she'll be fine. What about losing six or seven years of pop-culture references and being up on the latest gadgetry? That'll probably hurt a lot more. Chloe tells Clark that he can only save her by letting her go. Take that, Clark!
We're at some misty place at night that we can only assume is a place where Dr. Knox dwells, or at least where he hides dead folks. He opens the trunk of his car. It contains a body within a big roll of bubble wrap. Knox pulls the body out of the trunk and lets it fall hard on the ground. He drags it along. Ew. There to meet him is Lex. Lex applauds Knox for his ingenuity. Apparently, he was going to grind the body into fertilizer to spread that DNA all over Kansas. Damn, that corn sounds delicious now. Knox wishes Lex were a typical billionaire, chasing women across the globe. When you're a billionaire, I think they chase you. Also, wrong gender, doctor. Knox thinks Lex is messing with science he doesn't understand. Lex warns Knox that his killing spree stops now. Lex says he's not going to let Knox hurt one more person. Knox says that the patients he murdered are the chosen few. They're all Jewish? Knox says the whole brain-surgery thing was just a front to find what he was looking for among Lex's collection of meteor freaks. Lex pulls a gun on Knox and threatens to shoot him. Knox just laughs. Knox pulls back his arm to swing and Lex shoots him, about six times, right in the heart. Knox falls. Lex breathes heavily. Knox raises his head and grunts, "Son of a bitch!" He's alive! Knox stands up, plucking bullets out of his wounds. He tells Lex that he's been speared by Mayan warriors, and he's survived Mongols' arrows and Crusaders' blades. He asks what makes Lex thinks that bullets from a nine-millimeter could slow him down. Knox smacks Lex across the head with his flashlight. Lex goes down. Does he get a prize for one-millionth concussion? Lex falls. Knox moves to swing again. Clark is there first, punching Knox into an electrical panel, which sparks up. Knox is electrocuted. Clark picks up Lex and whooshes him out of there. After Clark is gone, we see Knox open his eyes. There can be only one Dean Cain!
