The Primary was a Wraith queen who was in control of an alliance of several Hive Ships. When "Todd" planned a go-ahead for Dr. Jennifer Keller's plan from Michael's database, to eliminate the Wraith's need to feed, "Todd" wanted to convince the primary. However, the Primary would only talk to another queen. Since "Todd" had none, they used Teyla Emmagan to work undercover as a Queen. Teyla originally thought that she was to convince her of the plan. However, when the two were alone with "Todd", he took out a knife and stabbed the Primary in the side of her neck, killing her. After that, Teyla had to take the blame and temporarily act as the new Primary, in order for Todd to take over the alliance and eventually enact their plan. (SGA: "The Queen")
Behind the scenes
- Apollonia Vanova previously played Korolev Weapons Officer in the Stargate SG-1 episode "Flesh and Blood".
- The Primary is the first Wraith Queen not to be played by Andee Frizzell.
- It is possible that this choice was made because Rachel Luttrell is considerably shorter than Frizzell, which would have made their brief scene together look ridiculous. The difference in actor might also explain why a queen of special rank was used instead of a general queen.
