Stargate: 10 Times The Show Made Huge Mistakes
4. Stargate Shares Uniforms
Walter Harriman is one of the constant faces of Stargate, appearing in both the pilot and closing episode of SG-1, along with the closing episode of Atlantis. He is as instantly recognizable as Jackson, Carter or Maybourne. However, it looks like no matter how recognizable you are in the SGC, you cannot always guarantee your own uniform.
In the seventh season two-parter Heroes, the various crewman and soldiers of the SGC are interviewed by a visiting documentary crew. When Harriman is interviewed, he is full of glee to tell them about his duties in the control room. He shows them the Iris and explains why he says 'Chevron Seven, locked!'
The camera zooms in on his face...and on his nametag.
Perhaps the clue was there all along...perhaps, this is not the prime universe at all. Perhaps Norman Davis has been a doppleganger all along!
