Outline (Episode)

As a mysterious new illness begins to spread throughout the Pegasus Galaxy, Teyla is convinced that the father of her child is trying to communicate with her through telepathic visions concerning it.

But when Dr. Keller discovers it to be a re-engineered form of the Hoffan virus (Poisoning the Well), which renders surviving humans poisonous to the Wraith, the team suspects that Michael is seeking revenge again.

Meanwhile, Teyla follows her visions and is kidnapped by Michael who reveals his plan to take over the galaxy for himself with his new Wraith-Human hybrid species of which many Athosians, including Kanaan, her child’s father have been turned into.

The Hoffan virus is intended to weaken the Wraith and make them more vulnerable to attack.

With the help of Todd, the team locates Michael’s base but arrives too early and Michael is not there.

Michael’s ship engages the Daedalus which is hampered by the fact that it cannot destroy the enemy ship without killing Teyla.

Michael’s ship ultimately flees the battle with Teyla still on board.

To their shock, the team finds Doctor Carson Beckett, who has been dead for over a year, held prisoner inside Michael’s base.
