This preview clip was among the three holiday episodes premiered at this year’s Syfy Digital Press Tour. Warehouse 13‘s holiday episode, “The Greatest Gift”, airs on Dec. 6 at 9/8c, immediately following a special Christmas episode of Eureka. In this special stand alone, Pete 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 recognise 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.
