But things go badly when Ronon is kidnapped by a Wraith who tortures him, and a non-lucid Tyre may be the only person who can save Ronon before the Wraith brainwash him. After going through withdrawal from the Wraith enzyme, Tyre leads the team to the lab where Ronon is, but turns on them to get another fix after Ronon is revealed to be brainwashed. The Wraith tries to torture Sheppard, but Tyre reveals that he was faking his return to the Wraith and battles Ronon while Sheppard battles the Wraith.

The Wraith capture Beckett and McKay and force them to work on a system to detect survivors of the Hoffan plague, but it allows Beckett to determine he has the drug too and he uses it to kill the Commander and escape.

Xiao Shen, an IOA dignitary, comes aboard to judge Woolsey's ability to be a capable commander and is planning on using this situation so she can get control of Atlantis herself. Eventually it is revealed that both Kolya and a woman Woolsey was attracted to are projections of the Sekkari AI trying to distract Sheppard and evaluate Woolsey. The AI wants Woolsey's help to save its race from extinction by transporting it to its target world after it had crashed on Atlantis' home world thousands of years ago. It was trying to distract Sheppard as he was the greatest threat to it, but it never meant him any harm. Woolsey decides to help it even though it could cost him his job and has the Apollo transport it where it needs to go. As a final thanks, the AI tricks the dignitary and saves Woolsey's job.

The team investigates mysterious happenings on board a Wraith Hive, where Todd and his crew are suffering from a disease, just to find that since Wraith ships are organic, the ship has the disease as well. It's revealed they got this disease when they tried Keller's gene therapy which did work, but left them with a weakened immune system. Todd offers a possible solution: allow them to be fed on by an iratus bug queen but Sheppard refuses. At the same time the team has to deal with feral Wraith warriors and the ship's deteriorating condition. Eventually the ship splits in half, killing all but the team and Todd, but the front half falls into the planet's atmosphere. Todd manages to land it in the ocean and everyone is rescued by Atlantis before the ship sinks. Keeping a deal he made with Todd and believing Todd could be a powerful ally, Sheppard sends Todd through the Stargate to seek his cure.
98	18	"Identity"	William Waring	Carl Binder	December 12, 2008 (2008-12-12)
Dr. Jennifer Keller is diagnosed with a psychological ailment. However, little does the Atlantis expedition realize that she has been exposed to body-switching technology, similar to the one that SG-1 found in the SG-1 episode "Avalon" that does not require the subjects to be in close proximity. Meanwhile Keller's consciousness faces a desperate struggle for survival inside the body of a wanted fugitive woman named Neeva. Eventually the team finds the device and Ronon destroys it just as Keller is about to be killed by Neeva's associate. Neeva is then presumably killed by her former associate, but both disappear so her fate is unknown.
99	19	"Vegas"	Robert C. Cooper	Robert C. Cooper	January 2, 2009 (2009-01-02)
In an alternate reality, Detective John Sheppard and FBI Agent Richard Woolsey find themselves in the midst of a CSI-like murder case involving several killings apparently of Wraith origin in Las Vegas, Nevada. It's eventually revealed that this Wraith is the only survivor of a hive ship that attacked Earth and was destroyed. The Wraith plans to send a transmission to the other Wraith to lead them to Earth, but Sheppard finds him and enters a gunfight that leaves Sheppard mortally wounded. As the Wraith is about to kill him, two A-10 Thunderbolt IIs sent by Woolsey - whom Sheppard alerted earlier through Dr. Rod McKay - arrive. The Wraith quickly activates his transmitter before the fighters destroy it and him. The transmission never reaches Pegasus, thus saving the alternate Earth, but is sent through to other realities where it will reach Pegasus. It is suggested that the Rodney McKay in this reality is the same that visited Atlantis in the Season 3 episode "McKay and Mrs. Miller".
100	20	"Enemy at the Gate"	Andy Mikita	Joseph Mallozzi & Paul Mullie	January 9, 2009 (2009-01-09)
Todd informs Atlantis that a group of Wraith have in their possession several ZPMs which they plan to use to power a new super Wraith Hive. He also advises Woolsey that they should immediately destroy it. But when the team reaches the hive, it does significant damage to the Daedalus and jumps into hyperspace. The team then finds out that the ship has received the signal sent from alternate Earth in "Vegas" and is heading to Earth. The hive shrugs off all efforts to destroy it, including an attack by Atlantis itself, but at the last minute, Sheppard destroys the ship with a nuclear weapon and saves Earth. Atlantis is forced to land on Earth due to lack of power.
