The Greatest Gift

S3 E13: In Warehouse 13's "The Greatest Gift," Pete Lattimer (Eddie McClintock) is hit in the head by an artifact and wakes up to a life where he was never born. Pete must hunt down and persuade the Warehouse team (none of whom recognize him) to go on this life or death mission with him to vanquish a long dead nemesis from the past to get everyone's lives back. This episode takes a page from It's a Wonderful Life and The Greatest Gift, which is the short story on which the iconic movie was based. As he did last year, showrunner Jack Kenny directed the holiday episode.
