Clark's future boss at the Daily Planet shows up; Perry White, but this time around he's a dirt bag reporter working for the tabloids.

While Lex continues to investigate the dark past of his father, he meets Morgan Edge with a new face after plastic surgery, and collects evidence to send Lionel Luthor to prison for the murder of his parents. However, a hit man tries to kill Lex in the mansion, but he escapes to Kent Farm. Clark goes to the mansion to retrieve the evidence against Lionel from the safe and finds that there is no hint of the claimed attempt against Lex's life. When Lionel goes to the Kent Farm and tells that Lex is paranoid and delusional over the death of Lex's infant brother years ago, Jonathan and Martha question his sanity. Clark decides to investigate deeper to see if his friend is delusional or there is an evil plot against him. As it turns out, the answer is literally... both. Although Morgan Edge is indeed alive and after both Lex and Clark, Lex's paranoia is real, which leads to him injuring Lana after he suspects her to be a part of the conspiracy against him. Clark then tries to stop Lex from killing Morgan, and in so doing is forced to reveal his secret to Lex.

Lex is committed to the Belle Reve Sanitarium for the criminally insane by Lionel who forces the shrink, Dr. Claire Foster, to submit Lex to an experimental electroshock therapy technique to erase his memory and forget his past events. Clark visits Lex and after finding out, decides to try to save his friend, despite protests from Jonathan and Martha that Clark's secret is known by Lex. But three of Clark's adversaries reside in Belle Reve. They are the arrogant, power-stealing Eric Summers (from episode "Leech"), the angry, meteor-rock mutant racist Van McNulty (from episode "Extinction") and the double-clone Ian Randall (from episode "Dichotic") who join forces to attack him so Eric can steal Clark's powers again and and escape from the asylum. Meanwhile, Lana begins to distance herself from Clark while she's attending physical therapy to recover from her broken leg with the support of a charming patient named Adam Knight (Ian Somerhalder).
