Smallville Season 4
Clark Kent will have plenty of reasons to remember his senior year! Lois Lane — smart, opinionated, and entirely annoying to Clark — arrives in Smallville to investigate the death of her cousin. Lana gets a new older boyfriend. Clark decides to go against his parents' wishes and joins the football team as a quarterback. And while Clark sets off on a quest to find three mysterious Kryptonian crystals, Lex steps further from the light into darkness.
01. Crusade
Clark returns to Smallville as Kal-El - intent on fulfilling his destiny, he goes after a powerful kryptonian crystal that Lex has obtained in Egypt. Meanwhile, newcomer Lois Lane arrives in Smallville to look into the death of her cousin Chloe, and Lana returns from Paris with a new boyfriend. Jonathan lies in a coma after the events of last year's season finale and Lionel must deal with his new life in prison.
