This week on Z Nation, Warren's (Kellita Smith) dream leads our heroes back to Mercy Labs from the season three opener No Mercy. Images in her dream drive her to search the destroyed complex and find a mysterious cylinder of gas which she is compelled to bring along, without knowing why. Check out the clip below and then make sure not miss Return to Mercy Labs on Friday, December 8th @ 9:00 p.m. EST/8:00 p.m. CT on SYFY (US).
