This season provided the show's first glimpse into the Phantom Zone. The destinies of Lionel and Lex play out in the aftermath of Lex's possession by Zod and Lionel's adoption as the oracle of Jor-El. Several criminals escape the Phantom Zone with Clark, and DC Comics characters Jimmy Olsen, Oliver Queen and Martian Manhunter are introduced this season, and the first glimpse of the Justice League is seen when Victor Stone, Arthur Curry, and Bart Allen all return to Smallville. Lex's relationship with Clark is completely shattered as his relationship with Lana progresses. Lana soon discovers she is pregnant and decides to accept his proposal of marriage.
Lana and Lex's relationship dissolves when she discovers the truth about her pregnancy while simultaneously discovering Clark's secret. She tries to leave Lex and Smallville with disastrous consequences. As Lex, Clark, and Lionel all search for the missing Phantom Zone escapees, Lex's Level 33.1 project advances dangerously. It becomes personal for Lois when Lex exploits one of her childhood friends and she vows to take him down. Lois and Clark have their first kiss, shadowing their future relationship.
