Carter certainly got around two galaxies with numerous roles. She's served as SG-1's second in command, SG-1 team leader, temporary SGC commander (twice?), Area 51 R&D, Midway Station, Atlantis Expedition leader, and George Hammond commander. Did I miss anything? We saw her as SG-1's second in command more than anything else. Regardless, which role did you think suited her best? For me, it was being in charge of Atlantis. Though it was an administrative role, think about all of the technological and scientific marvels she'd have access to. Though McKay made her wish she was somewhere else, think about how he could challenge given how smart he is. It only lasted some 15 episodes, but this was my favorite role for the character.
