Jason has the most atrocious nightmare of his life, about Lana leaving him for Clark, catching and separating them in the Kent barn and being stabbed by her. But he doesn't just wake up, but in hospital with symptoms of a continuing nightmare. Soon, many others in Smallville have similar experiences, even Clark, whose superpowers fortunately save him so he can find out the source of the epidemic is a failed experiment on Luthor Corp's fertilizer plant site, where an explosion released a hallucinogen bacteria being developed under a military contract, so he can help Lex deal with it. Meanwhile, Lionel, who had settled in prison, finds himself mysteriously scheduled to be released, which all his means could not achieve when he still desperately wanted to get out.

Chloe Sullivan: So, popular question of the day: what is Clark Kent's worst nightmare?
Clark Kent: When I woke up, everyone that I knew was gone. I was completely alone.
Chloe Sullivan: I wish I could say that I'll always be there for you, but somehow I get the feeling that may not be a promise I can keep. You were the only one that came out of it, Clark, and I don't think it's because you've been taking your vitamins.
Clark Kent: Chloe...

Nightmare at Luthor Corp.
31 May 2006 | by See all my reviews

After having a scary nightmare, Jason Teague is interned in Metropolis Health Center with risk of death. Clark Kent and Chloe Sullivan decide to investigate, and find that Jason had had a meeting at Luthor Corp. a couple of hours before. They go to the plant, and Chloe has the same trouble. Sooner, many dwellers of Smallville have the same mysterious disease, and Clark finds that it is caused by an experimental bacteria released from Luthor Corp.'s laboratory after an explosion in the facility, and the team of scientists is working in an antidote. Meanwhile, Lionel Luthor is released from prison.

"Scare" is an episode that recalls "A Nightmare on Elm Street", where Luthor Corp. would be the Freddy Krueger. The story is excellent, and the nightmare of Lex Luthor recalls a scene of "Terminator 3: Rise of the Machines". I have a guess of who set Lionel Luthor free from the prison. My vote is nine.

Title (Brazil): "Susto" ("Scare")
