One of the things that I mentioned in my previous post is that Daniel is my One True Character for Stargate. There is no moment in canon where I disconnect from him, no moment where I don't feel like I understand him. For me, Stargate is entirely and completely Daniel's story. He is the catalyst for all of the action. He solves the Stargate, he unburies the gate of Abydos, he finds Atlantis, and he's the one who opened the door to let the Orii know that we existed.
