In "Search and Rescue," Carter was replaced by Woolsey. There was vague dialogue about being the victim of her own success. What does that mean? Vague. In the series finale, we discover she's back on SG-1. During the events of the finale, she had temporary command of the SGC while Landry was in Washington. Why didn't he come running back during the crisis??? Anyway... We learn that she's going to be given command of the George Hammond which we see in the first Universe episode.
Do you see command of a Daedalus-class ship as a step down from commanding Atlantis?
