Misbegotten

S3 E2: Having successfully used the Wraith retrovirus to turn an entire hive ship of Wraith into humans the team returns to Atlantis with their prisoners in stasis. Weir (Torri Higginson) continues to defend her leadership in the face of an independent review being conducted by IOA member Richard Woolsey (Robert Picardo). Examining the hive ship that the team hijacked in an attempt to restore it to full working condition McKay (David Hewlett) discovers that the Wraith prisoners cannot continue to be held in stasis indefinitely. The team decides the best thing to do is to set them free on a planet under the guise that they were exposed to a viral outbreak. Sheppard (Joe Flanigan) and Dr. Beckett (Paul McGillion) remain on the planet to manage the human-form Wraith including a re-humanized Michael (Connor Trinneer). But when they discover a Wraith ship approaching the planet the team must act fast to keep the existence of Atlantis a secret.
