I like this episode - the story. It was one of those episode where there really was a story - deep and moving. It was great storyline - what happened with O'Neil's son and it was a smart idea to take it up and use it for this episode. The way the wrong O'Neil tried to understand the human pain, the way humans die - it was another really great philosophical dilemma. And the way Teal'c tried to understand Earth - and all the thing with weapon - I will need it if I go out. It was great moment.
Really deep story episode.
