In the SG-1 episode "2010" we learn that "Chevron Guy's" name is Walter Davis. Yet, Gary Jones's filmography page over at IMDb.com now lists all of his apperances as Sgt. Walter Harriman (minus the "Children of the Gods" credit, there it's Walter Norman). I also remember watching an interview with him on one of the DVDs where he said his name was Harriman Davis. What's the deal?
