The Long Goodbye

S2 E16: On the way to investigate a potential source of energy the team encounters two pods in orbit around a moon. They decide to take one back to Atlantis for observation. Upon opening the pod they find a woman in stasis. As they speculate about her age an energy beam emanates from the pod and hits Weir (Torri Higginson) allowing her to harbor the consciousness of the woman inside the pod. Through Weir the team learns that the woman Phoebus was from a race of explorers whose vessel was attacked by the Wraith. She claims that the body of her husband Thalan occupies the second of the two pods found by McKay and her wish is for the team to bring him back to Atlantis so that Sheppard (Joe Flanigan) may harbor the man's consciousness and allow him to communicate one last time with his wife. Unfortunately once the plan is put into action the team learns that it was all a ruse: Phoebus and Thalan were enemies and her real intent was to have the team revive Thalan so she could finally finish him off. Now as Phoebus and Thalan wreak havoc throughout Atlantis in the forms of Weir and Sheppard the rest of the team must find some way to stop them before they destroy each other - and Atlantis itself!
