Having one of the team members masquerade as one of the enemy isn’t an unusual concept in the Stargate universe. Remember Daniel in the Stargate SG-1 episodes Summit and Last Stand? However, I haven’t seen an episode before in Atlantis that covers the same ground, until now.

The Queen brings back Todd the Wraith and begins with a meeting between his hive ship and Sheppard’s Atlantis team, Dr. Rodney McKay, Ronon Dex, and Teyla Emmagan. The team would like to convince the Wraith through Todd to consider the treatment Dr. Jennifer Keller has developed to cure the need of the Wraith to feed on humans. Todd considers the idea, and frankly, Lt. Col. John Sheppard is suspicious, and rightly so. Todd comes back with his own proposal–that Teyla masquerade as his Queen.

Teyla’s DNA has traces of Wraith DNA (mentioned in previous episodes) that will allow her to disguise herself as a Wraith Queen and successfully fool the Primary, the Wraith Queen who is in charge of the entire Wraith alliance. No one else has the ability to pull this off, and so Teyla feels bound to help.

But when she and Todd are successfully aboard the Primary’s hive ship, they encounter unexpected developments that appear to force a change in their plans. Does Todd have a hidden agenda? Will Teyla be able to maintain her masquerade, or will they be discovered and killed?
