This episode is a revealing episode, I suppose one could call a crossroad episode or at least a pre-crossroad episode. One of the teams plans has bit them in the butt. The Aurans plan to make the wraith starve to death by killing worlds and the team must work with the Wraith to halt the replicator advance.
This episode brings up issues such as the paradoxial "shaking hands with the devil to do the lords work." It also makes a startling revelation, the International Oversight Committee has stated that beuracratic and political interference is not as productive as they would like!! Here is another startling revelation...Ice is Cold!!! and Fire is Hot!!!
Anyway, back to being serious, the episode finally reveals that although the Athosians vanished, they are still alive.
Also Teyla is pregnant which is sure to lead to interesting conundrums in the future. What is interesting about "The Seer" is that all of the visions except for the last one all came true except the circumstances surrounding them were not as they seemed. Yes they were captured by the Wraith but then the Atlanteans ambushed the Wraith back! And the Wraith Hive ship was destroyed but not by John Sheppard but by another ship, Truly Master Yoda's words were true... "always in motion in the future."
