Cool

Clark has a chance to share a night out on the town with Lana, thanks to Lex's matchmaking, but the evening is interrupted when Clark faces an icy enemy, Sean Kelvin (Michael Coristine). Sean is an aggressive flirt who suffers from a Kryptonite-induced case of permanent hypothermia and has to feed off of others' body heat to survive -- starting with Chloe.
