“Spoils of War” is episode twelve of season four of Stargate: Atlantis.
It had previously been discovered that Teyla possessed Wraith DNA, allowing her to control Wraith ships. The end of the battle from the previous episode, “Be All My Sins Remember’d”, is shown at the beginning of this episode from the Todd the Wraith’s point of view. He had sent a couple of Darts to the Replicator homeworld to steal some Zero Point Modules.
Todd’s transmitter is discovered by the Atlanteans, who dispatch a team. When his ship is discovered to be abandoned, Teyla joins the rest and they take it to its destination, a secret Wraith base that had proved important in their battle with the Lanteans.
Yet again, they get a new ship, and yet again they lose it. That’s becoming a bit repetitive.
