"Great"
Lois is working at the Talon, when a young man named Kevin brazenly lifts all the cash from the till (that's two Talon thefts in two weeks), then zaps Lois with hand-rays, and instantly she's forgotten what she just saw. This is the episode theme - a strange power being misused, and it's threat to Clark. When Clark pursues the memory-muncher, he too gets zapped, and he's "Blank." Chloe takes him home (not to a hospital for a physical?), but Clark recognizes nothing and knows little but how to walk and talk and behave like a civilized being, except for ripping the front door off it's hinges.
Lois is made to seem unimpressed by the whole amnesia case - hey, people! - this could be a head injury! Chloe is now mighty suspicious, so she asks Clark to bend steel in his bare hands and go jogging - in seconds, he's miles away in a cow pasture. Chloe doesn't have to be suspicious any more, but she thinks he's merely meteor-rock infected. Back at the Talon, Chloe begins to realize he can see through objects too, as he spots something left by the thief. Upstairs, Lana tells Jason she may not go away to college, too many secrets between the two. Jason asserts, "You have no idea how much I've been protecting you." Clark's attraction to Lana is still intact - quick, Chloe, get him home! What, they let him go back to school? Clark wants to know what happened with Lana, and for things to be different.
Together, Chloe, Lois and Clark get a lead on memory-thief Kevin, whose father admits he escaped from the notorious Summerholt Institute, where memory erasure was being tried on him to relieve the trauma of his brother's accidental shooting death. Chloe and Clark question Lex about the Institute, but Chloe unwisely leaves Clark alone with Lex, who forthwith takes Clark to the caves to question him. "Blank" Clark still trusts his instincts and reveals nothing to Lex.
Chloe, ever the skilled snoop, finds Kevin's medical record at Summerholt, but someone grabs her. Kevin is off in the woods, trying to remember the shooting incident, and Clark has followed him. In a series of flashes, Kevin remembers - his father was the shooter, not Kevin, so Clark and Kevin team up. Lois has pulled Sheriff Adams into the mix, and they confront the staff at Summerholt about Chloe's disappearance. Kevin and Clark arrive, Clark is weakened by meteor rock. Chloe is about to get the big memory erasure by another mad scientist - Kevin's father! Clark intervenes to stop the threat to Chloe, and the memory-beam hits him instead, reversing his memory loss. This super-rescue is seen by Lois and Sheriff Adams, so Kevin quickly zaps their recent memories again. Clark doesn't remember the previous 24 hours, but he knows he owes Kevin - they part friends. Back at the farm in his silver Mercedes SL 500, Lex has found Clark's drawings of cave symbols, while Clark makes a reconciliation pitch to Lana. When Clark next sees Chloe, she doesn't reveal what she now knows about his powers, and when he asks, "What did I do?" she simply replies, "You trusted me." Chloe's insight is a major development and this episode is not to be missed. Rerun rating B.moreless
