About 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.
