Ready for a belated Valentine's Day?

Due to the January 22 Hope for Haiti Now telethon, followed by the special "Absolute Justice" episode that had been scheduled for February 5 for months, Smallville was forced to shake up its schedule a bit.

As a result, the show is airing its Valentine's Day-themed installment this Friday. On "Persuasion," Lois will fall under a spell and a wedding will be teased. Watch the official CW trailer:
