Todd contacts Atlantis and reveals that a Wraith subordinate has managed to acquire several zero point modules that he has used to power a formidable new hive ship. He urges Woolsey to attack and destroy before it becomes a threat to Atlantis. On board the Daedalus, Colonel Caldwell, Colonel Sheppard and the rest of the team, rush to engage the new hive ship. But the ZPM powered vessel proves itself an impressive opponent, crippling the Daedalus before making a sudden and inexplicable jump into hyperspace. Puzzled over the Wraith's sudden departure, the team picks up a weak subspace signal in Wraith code. McKay is quick to recognize that the communique was sent, through subspace, from another reality. Once deciphered, their worst fears are realized. The Wraith message contains a familiar set of coordinates. The hive ship is on its way to Earth!

Allies

Mar 10, 2006 Season 2 Episode 20

A Wraith hive ship arrives in orbit above Atlantis. In the cloaked city below, everyone is stunned when Michael radios down with an unnerving request: He wants to negotiate an alliance. Frustrated in their quest to locate Earth, the Wraith are now running short of their food — humans — and have begun fighting among themselves. For this reason, Michael seeks a weaponized version of Dr. Beckett's anti-Wraith retrovirus, which briefly gave him a human body. He wants to deploy it against rival hives, turning them human and feasting on the results. His hive will gain food and power, and the Atlantis team can deal a fatal blow to thousands of their enemies. Weir and her senior staff decide that such a payoff is worth the immense risk of trusting the Wraith, and soon the new allies are working side-by-side. With the help of a Wraith scientist, Beckett and Zelenka struggle to weaponize the retrovirus, while McKay coordinates with the hive's crew to practice bypassing a hive ship's defenses. The Wraith, however, make everyone uneasy. Worse, their first attempt to target another ship with the new weapon ends in disaster: Their enemies discover the canisters of the retrovirus too soon and open fire. Michael's hive ship and the Daedalus barely escape intact. The imperious Queen of Michael's hive now threatens to reveal Atlantis's existence to all the Wraith if the humans won't design a reliable delivery system for the weapon. McKay, frustrated, demands that she help by allowing him free access to every last piece of information about Wraith ships. To his astonishment, she agrees, downloading a virtual encyclopedia of technical specs to Atlantis's computers. Zelenka delves into this goldmine of strategic intelligence while McKay — escorted by Ronon — explores the hive itself and discovers a perfect delivery point for the retrovirus in the atmospheric system. With that, they're ready to attempt a second attack: The Daedalus will beam the canister onto another enemy hive. McKay and Ronon will observe from Michael's ship. Sheppard will observe from the Daedalus. But soon after the mission is underway, Zelenka discovers that the electronic Wraith encyclopedia was infected with a virus of its own — and now that virus is loose in Atlantis's computers. It's too late to warn the Daedalus, which drops out of hyperspace to find itself trapped under a ferocious bombardment from two hives — the enemy vessel and Michael's ship. The alliance was nothing but a ruse; the real plans of the Wraith are far more sinister. Far from giving up on finding Earth, they've just tricked the Atlantis team into giving them exactly the information they need to get there.

Inferno

Mar 03, 2006 Season 2 Episode 19

Sheppard's team visits the planet Taranis at the invitation of two leading citizens, Dr. Norina Pero and Chancellor Lycus, who want McKay to repair a failing shield generator at an Ancient base they've discovered. Lycus also shows the team a massive Ancient warship, much like the Aurora, hidden in a vast warren of tunnels beneath the base. Although the warship is damaged and currently inoperable, Dr. Weir eagerly opens trade negotiations with Lycus as soon as she learns of its existence. As mysterious earthquakes rattle everyone's nerves, McKay overcomes his attraction to Dr. Pero long enough to discover that her people have seriously overtaxed the shield's capabilities. Worse, the shield's energy source is the magma chamber of a supervolcano beneath the base — a volcano that has been destabilized by the excessive energy demands. A catastrophic eruption is now imminent: Half the continent is about to be ripped apart, rendering the entire planet uninhabitable. Everyone must evacuate. As the earthquakes grow stronger, local villagers begin arriving at the base through the relative safety of the Ancient tunnels. Weir and Lycus lead some of them through the stargate to Atlantis, but seconds later, the ground around the 'gate erupts. The stargate sinks forever into a pool of molten rock. From Atlantis, Weir immediately dispatches the Daedalus to Taranis, but it will require multiple trips to evacuate everyone. Sheppard and McKay, knowing that they don't have that much time, start repairing the Ancient warship while Teyla, Ronon, and Dr. Beckett hurry to a nearby settlement, to organize the first group of evacuees. Soon after the Daedalus departs from Taranis, new vents erupt, ash starts falling, and the outside air turns toxic, forcing Beckett, Teyla and Ronon to send the remaining villagers through the tunnels to the warship. Then McKay discovers that a lava flow has sealed the main hangar doors shut. Now, even if he can repair the ship, they'll still have to find a way past this molten barrier. Teyla and Ronon remain in the settlement until they've rounded up the very last of the villagers, only to be trapped when the tunnel that leads to the base collapses. As the duo fights to stay conscious in the deadly air, Sheppard notices that they're missing and descends into the maze of tunnels to find them. Soon he's cut off, too — and even if he somehow makes it back, there's still no guarantee that McKay can even get the warship off the ground.

Coup D'etat

Feb 17, 2006 Season 2 Episode 17

When a village on a distant planet is ravaged by fire, the team is called in to investigate the damage. In the attack, Major Lorne, a member of an off-world team working there, has seemingly disappeared. Upon further investigation, Teyla (Rachel Luttrell) and Ronon (Jason Momoa) find a wanted list circulating about the village – and on it is Major Lorne's name – along with those of Sheppard (Joe Flanigan) and McKay (David Hewlett). Weir (Torri Higginson) quickly deduces that whoever composed it was seeking people with the Ancient certain gene that provides the ability to operate Ancient technology, including Ancient ships. Compounding matters, the team is contacted by Ladon Radim, a former Genii. Now claiming to have severed ties with Atlantis' old foe, Ladon has an offer: a valuable zero point module in exchange for their help in planning a coup against the Genii. Ladon claims the Genii have been harboring nuclear weapons and are becoming an even greater threat. Skeptical of what they've been told, the team decides to alert Cowen, the Genii leader, of Ladon's plans. Cowen confirms that Ladon is no longer linked with the Genii, and thanks the men for the warning. Satisfied that the Genii pose no immediate threat, Sheppard and McKay plan a raid to simply "appropriate" the ZPM from Ladon. However, when they arrive, their team is taken hostage by Ladon and Cowen, who are, after all, still Genii accomplices. Their plan is to negotiate for Atlantis' Jumper ships which they intend to use to attack the Wraith. Now, Weir must negotiate with the Genii – before it's too late.

The Long Goodbye

Feb 10, 2006 Season 2 Episode 16

On the way to investigate a potential source of energy, the team encounters two pods in orbit around a moon. They decide to take one back to Atlantis for observation. Upon opening the pod, they find a woman in stasis. As they speculate about her age, an energy beam emanates from the pod and hits Weir (Torri Higginson), allowing her to harbor the consciousness of the woman inside the pod. Through Weir, the team learns that the woman, Phoebus, was from a race of explorers whose vessel was attacked by the Wraith. She claims that the body of her husband, Thalan, occupies the second of the two pods found by McKay, and her wish is for the team to bring him back to Atlantis so that Sheppard (Joe Flanigan) may harbor the man's consciousness and allow him to communicate one last time with his wife. Unfortunately, once the plan is put into action, the team learns that it was all a ruse: Phoebus and Thalan were enemies, and her real intent was to have the team revive Thalan so she could finally finish him off. Now, as Phoebus and Thalan wreak havoc throughout Atlantis in the forms of Weir and Sheppard, the rest of the team must find some way to stop them before they destroy each other - and Atlantis itself!

Inside the tower, Sheppard is introduced to the dying Lord. When the Lord and his advisors discover that Sheppard also possesses the Ancient gene needed to protect the village, they decide that he should marry into the family and become the Lord's successor. While McKay (David Hewlett) investigates the source of the Protector's power, the Atlantis team tries to free the people from this unjust ruling family, but is unwittingly caught up in a devious power play.

Critical Mass

Jan 20, 2006 Season 2 Episode 13

General Landry (Beau Bridges) informs the team that the Goa'uld have planted a bomb on Atlantis and will be triggered by any attempt to dial the gate. After some investigation, McKay (David Hewlett) determines that the failsafe mechanism on Atlantis' energy source hase been disabled -- so any action that might cause it to overload (such as dialing the gate) would result in an explosion. Furthermore, the mechanism is now locked with an unbreakable code, and they must find the individual who tampered with it in order to enable it once again. To make matters worse, two Wraith cruisers are headed straight for Atlantis. They must activate the cloak in order to keep the city invisible to the Wraith - but such an operation would surely cause the energy source to detonate. With time running out, an alarmed Weir (Torri Higginson) launches a full-scale investigation to find the saoteur. She is shocked when she discovers that the perpetrator is a member of her own team.

Epiphany

Jan 13, 2006 Season 2 Episode 12

After detecting an energy spike over a forested area on a distant planet, the Atlantis team decides to investigate. Their travels lead them to a portal built into a rock wall with Ancient carvings and a portal built into it. Intrigued, Sheppard decides to test the portal to see where it leads, and before he can stop himself, is pulled through to the other side with no way to get back or communicate with the team. When no rescue team comes through the portal, Sheppard explores his surroundings and he encounters Avrid (David McNally), a man on the run from a dangerous creature. After a violent showdown, Sheppard succeeds in warding off the creature. Avrid then brings the injured Sheppard back to his home to recover. There, Sheppard discovers that all the inhabitants of the planet are direct descendants of the Ancients, and he is the only one ever to have survived such an attack. Meanwhile, the rest of the Atlantis team is trying to figure out what happened to him. After translating the writing on the rock wiht the help of some Ancient textbooks, Weir (Torri Higginson) discovers that Sheppard has been transported into a time dilation field, designed by the last of the Ancients as a sanctuary from the Wraith -- a place where people could live in peace and saftey and ascend to a higher plane of existence. However, there are also a warning inscribed on the stone: once the threshold across the portal is crossed, there is no return.

McKay, who is still stranded on Ford's planet, soon realizes that the team has been captured. In order to escape the planet, he comes up with an unconventional plan: he injects himself with a massive amount of the dangerous Wraith enzyme. The drug provides him with brute strength, and after knocking the guards that surround him unconscious, he is able to dial the gate and leave the planet. When he arrives on Atlantis completely incoherent, Dr. Weir (Torri Higginson) and Dr. Beckett (Paul McGillion) put him under immediate medical supervision. Once recovered, McKay is able to calculate the location of the ship upon which the team is stranded.

Laura Cadman (Jamie Ray Newman) are transported aboard a Wraith Dart, which subsequently crashes.

Zalenka believes that she is still trapped inside the Dart, until McKay claims to hear her voice -– coming from inside his own head! It seems that Zalenka's experiment, rather than saving the two separately, caused them to unite –- and Cadman must remain inside of McKay's head until Zalenka can figure out a way to separate the pair. Meanwhile, as Ronon Dex (Jason Momoa) settles in at Atlantis, he shows off his impeccable fighting skills during arsenal training. Impressed, Sheppard (Joe Flanigan) implores Weir (Torri Higginson) to put aside her reservations about the newcomer and consider allowing Ronan to join the Stargate Atlantis team.

Intruder

Jul 22, 2005 Season 2 Episode 2

When a scientist is killed in the Daedalus' computer room, McKay (David Hewlett) first believes the poor circuitry is at fault. However, when another scientist is killed while investigating the death, McKay begins to suspect that someone – or something – is deliberately planning these breakdowns. Soon after, McKay is alerted to a virus on one of the ship's computers. When he runs its code through a translator, he is shocked to discover that it is written in Wraith. Even worse, he learns that the virus has the ability to re-write itself, making it seemingly impossible to conquer. Realizing that the program’s capability to mutate has virtually given it a mind of its own, McKay worries that the Wraith may use the virus to take control of the ship – with potentially deadly results. As feared, the virus' artificial intelligence soon takes control of the Daedalus' auxiliary ships, and the crew becomes increasingly powerless to defend themselves. Fearing that the Wraith will use the Daedalus' advanced features to attack Atlantis, McKay and Sheppard (Joe Flanigan) race against the clock to counteract the virus before the Wraith turn the Daedalus’ advanced technology against the city.
