Codename: Christmas Carol

Merry Christmas, maybe?

It's the Clark family's first Christmas together, but Kristian doesn't think there's much to celebrate on the run. Enter three agents from the future who are determined to turn his Scrooge-ness into Christmas cheer in attempt to prevent a coming tragedy. But will they succeed in their mission or merely assist him in dooming his own future?

He'd better be good- or else.
