Smallville :

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, who has fallen into a frozen lake infected with Kryptonite. 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.

Sean heads to Lex's mansion and freezes Clark en-route. Clark's body reheats itself, and he arrives at the mansion just as Sean is about to attack Martha, who came with Jonathan to discuss their financial troubles with Lex. During the fight, Clark throws Sean into a lake, which immediately freezes with Sean inside.
