Smallville Season 4

Clark has returned, though he isn't his usual self. Clark is "reprogrammed" by Jor-El, to seek out the Stones of Power from around the world.

Lois Lane comes to Smallville to search for the truth behind her cousin Chloe's death. Lois finds an amnesic Clark, returned to Smallville after a 3 month absence, and takes him to the hospital. Lana, still in Paris and with a new love interest, is researching an ancient martyr, Countess Margaret Isobel Thoreaux, which is connected to Lana in more ways then she knows. Jonathan lies in a coma with Martha by his side; Lionel awaits his trial.

Clark decides that this year will be the year of Clark and he will not be worried with what Jor-El has in store for him anymore. Clark goes out for the football team, goes through rocky terrain with his relationship with Lana, sees his relationship with Lex begin to fully crumble, meets future superheroes and old obsessions, and battles witches from the 17th century just in time to graduate from Smallville High. Clark's true destiny is also revealed to him by the season's end, and a second meteor shower comes to Smallville.
