The auto shop at night. The old man who runs the shop is heading out. Deadbeat Dad tells him g'night as he shuts off the lights. For a deadbeat, this dad sure does work some long hours. "We're closed. Come back tomorrow," he tells Evan as he walks right past the fruit of his grease-stained loins. "You deaf?" DD asks. "What're you starin' at?" Not great acting, that's for sure. Evan -- who has a bad habit of letting his mouth hang open when it's not putting words together -- says, "My father." DD tells Evan not to call him that, and adds that he's not the kid's father. "Yes you are," says Evan, sadly. "Why won't you admit it?" Because ladies won't sleep with an eighteen-year-old with a fifteen-year-old son. DD tells Evan to stay away. "Please, Dad, just help me!" the kid says, pathetically. He reaches out to his father and says he's his son. "No you're not!" DD argues. They tussle a bit. "You're some kind of freak!" DD yells. He pushes the kid away and rips off a piece of shirt as he does. DD falls back and hits something behind him. Blood comes out of his mouth. He was impaled on a random sharp object left out in case they needed to impale anything for an '88 Toyota Camry. Evan, mouth open, is horrified. "Dad?" he asks. Dad's dead. Evan goes to him and keeps saying, "Dad? Dad? My God. What have I done?" as the camera pulls back to a crane shot of the kid kneeling by his dead daddy's body. Can this episode get any more depressing?
Commercials. I'm too sad to watch.
Clark and Lex are at the auto garage. Great pistons! Clark, on the phone with Bo, and asks Bo to call if he finds Evan. They must have just met up there, because Lex asks what's going on. Clark tells him they lost the boy. "Well, let's make sure we can help him when he turns up," Lex says. Er, sure. That's cool. They spot the body of Dead Deadbeat Dad, nicely lit by an overhead lamp. "He's dead," Lex says. And beat. Clark finds a scrap of red plaid shirt in the dad's hand. "Evan," he says. Also, "tampering with evidence." Lex -- never one to shy away from bad news -- says they needed a living donor for the marrow transplant. Clark says that there has to be some other way to help Evan. Trip to Vegas? Lex says they need to track him down and seal him in a containment chamber beneath LuthorCorp. That's "help"? Clark disagrees. Lex says it's the only way to contain the blast from his final change. Clark says he won't just let the kid die. Lex says there's nothing they can do to stop that, but that if they don't isolate him, lots of innocent people will die, too. Exponentially!
