Season three follows Clark's constant fight against the destiny that his biological father, Jor-El, has in-store for him, and his guilt over the price Jonathan paid to bring him back to Smallville. Lex deals with the psychological breakdown he had when stranded on a deserted island, while the conflict between him and his father comes to a final blow. Clark's secret begins to weigh heavily on Pete, and the relationship between Clark and Lana hits a dead end. Writers also brought in several DC Comics characters, Maggie Sawyer, Morgan Edge, and most notably Perry White, in special guests spots.
