Season 2 Episode Guide

Episode 1 - Siege, Pt. 3

Rescued from a near-fatal encounter with the Wraith Lt. Aiden Ford (Rainbow Sun Francks) receives medical care at the Atlantis base. However his abnormally quick recovery leads Dr. Beckett (Paul McGillion) to worry that the Wraith who attacked Ford may have injected him with a harmful enzyme causing long-term and unpredictable damage. Meanwhile as the Wraith’s siege of Atlantis rages on Sheppard (Joe Flanigan) finds himself surrounded by the enemy. He is rescued by the timely arrival of Colonel Steven Caldwell (Mitch Pileggi) commander of the Daedalus. Launched from Earth and sent in to assist the Atlantis team during battle the Daedalus helps to defeat the Wraith’s first wave assault on the city. Their relief is short-lived however. The team soon learns that the Wraith are planning the next wave of their onslaught -- an entire fleet is about to descend on the city. With a little over a day before the assault Dr. Weir (Torri Higginson) realizes that the Daedalus will not be enough to fight the Wraith's forces. McKay (David Hewlett) devises a drastic plan - but there may not be enough time to perfect the complicated technology his plan requires before the Wraith arrive.

Episode 2 - Intruder

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.

Episode 3 - Runner

When a routine off-world science mission comes across a mutilated Wraith carcass the team suspects Ford may be involved. Intrigued they split into teams to investigate. Teyla (Rachel Luttrell) and Sheppard (Joe Flanigan) encounter Ronon Dex (Jason Momoa) a fierce warrior who survived a battle with a Wraith seven years earlier and has been on the run ever since. When Dex reveals to Teyla and Sheppard that Ford (Rainbow Sun Francks) has taken up residence on the planet they enlist his help to locate their friend. The duo hope to rehabilitate Ford to his former state. McKay (David Hewlett) eventually stumbles upon the increasingly incoherent and maniacal Ford and tries to reason with his former colleague and friend. However McKay begins to see how far gone Ford has become -- addicted to the enzyme injected in him by the Wraith who attacked him Ford has been brutally killing Wraith to get a fix of the solvent. Reluctantly McKay and the rest of the crew must face the realization that they may never be able to save Ford from what he has become.

Episode 4 - Duet

During an investigation of a planet leveled by a Wraith attack McKay (David Hewlett) and new security team member Lt. Laura Cadman (Jamie Ray Newman) are transported aboard a Wraith Dart which subsequently crashes. Unfamiliar with the Wraith technology Atlantis scientist Dr. Zalenka (David Nykl) is only able to transport McKay out of the rubble. Cadman’s body is nowhere to be found. 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.

Episode 5 - Condemned

When the Atlantis team sets out to a distant planet they land on a small island off the main coast and are attacked by a group of savages. Barely escaping the island with their lives the team is rescued by one of the planet's security vessels and brought to the considerably more civilized mainland. Once safely on shore the team learns that the island had been set aside for the banishment of prisoners and is susceptible to Wraith attacks. The rest of the planet however is immune to such Wraith assaults. Intrigued by this as well as by the planet's unconventional energy source the team tells Weir (Torri Higginson) of their discovery. However when Weir arrives on the planet to investigate further she begins to suspect that the mainland's idyllic environment may be the result of a sinister pact between the planet's leader and the Wraith.

Episode 6 - Trinity

While doing standard recon on a planet thought to have been destroyed by the Wraith long ago the team finds an Ancient structure standing intact amidst the ruins. After some investigating they discover that the monolith served as a military research facility where the Ancients worked to develop an advanced method of harnessing energy. When the Wraith attacked before the project could be completed the underdeveloped technology malfunctioned and destroyed the civilization. McKay (David Hewlett) theorizes that if the powerful technology is fully developed it could serve as a potent source of energy for Atlantis. Hope turns to fear however when McKay's first attempt at reviving the energy source results in the death of one of the Atlantis scientists. Despite the team's apprehension a determined McKay insists on moving forward with finishing the project. But can McKay unravel the intricacies of the Ancients' technology without putting himself and Sheppard in mortal danger?

Episode 7 - Instinct

During a visit to a distant planet the team discovers a village whose inhabitants live in fear of a Wraith residing in their midst. When the team sets out to confront the creature they encounter Zaddik (John Innes) a scientist who has been living with Ellia (Jewel Staite) a Wraith child for the past several years. Zaddik has developed a serum that works to satiate the young Wraith's appetitie and prevent her from feeding on him. Dr. Beckett (Paul McGillion) is intrigued by the serum having been eager to test an experimental retrovirus of his own that could give the Wraith humanlike qualities and rid them of their predatory instinct. Beckett meets with Zaddik and his supposedly tame Wraith companion hoping he can begin a controlled experiment on Ellia. However when Ellia downs his retrovirus the underdeveloped formula has the opposite of the desired effect.

Episode 8 - Conversion

Within hours following his encounter with the mutated Wraith child Ellia (Jewel Staite) Sheppard (Joe Flanigan) is shocked to find that his wounds have disappeared without a trace. Soon after he begins exhibiting other symptoms similar to the ones that plagued Ford following his own Wraith attack. Dr. Beckett (Paul McGillion) realizes that a small amount of the retrovirus that Ellia ingested is now in Sheppard's bloodstream -- and he is quickly mutating into the very creature that attacked him. As Sheppard becomes less lucid by the hour the team races against the clock to save his life and reverst he effects of the retrovirus.

Episode 9 - Aurora

When Atlantis's deep-space sensors detect the Aurora an ancient Atlantian warship at the edge of the galaxy Sheppard's team wastes no time hitching a ride to it aboard the Daedalus. Upon their arrival they encounter a Wraith scout ship. They destroy the scout before it can cause trouble — or so they hope. Sheppard leads his team onto the derelict warship where they discover hundreds of crewmembers frozen in stasis pods. Although technically alive the Atlantians are thousands of years old and their aged bodies can't survive the defrosting process. Still there might be a way to talk to them: McKay discovers that all the pods are linked by an active neural interface allowing the crew to coexist with each other in a virtual environment.

Episode 10 - The Lost Boys

While exploring a new planet Sheppard McKay Teyla and Ronon are ambushed by a group of men armed with Wraith stunners. They awaken to find themselves prisoners in a cave where they discover the mastermind behind the attack: Lt. Aiden Ford. Ford was last seen being captured by a Wraith dart after overdosing on a powerful Wraith enzyme. Now Ford invites his former teammates to enjoy a meal while he tells them how his enzyme-enhanced abilities allowed him to escape. Since that time he has recruited a group of followers all of whom are willingly addicted to the drug. To the team's horror Ford then announces that their meals are laced with the enzyme. Determined to prove that the enzyme is both safe and useful Ford intends Sheppard's team to be his living evidence and the expects Sheppard who remains free of the drug to be his witness.

Episode 11 - The Hive

Captured by the Wraith Sheppard (Joe Flanigan) Teyla (Rachel Luttrell) Ronon (Jason Momoa) and Ford (Rainbow Sun Francks) are being held hostage aboard a hive ship. As the team desperately searches for some means of escape they are shocked to discover a coalition of Wraith followers on board the ship. 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. As tensions rise on the hive ship between the Wraith and the Atlantis team he and Caldwell (Mitch Pileggi) must devise a plan to bring the rest of their team to safety.

Episode 12 - Epiphany

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.

Episode 13 - Critical Mass

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.

Episode 14 - Grace Under Pressure

On a puddle jumpter test flight McKay (David Hewlett) and a pilot suddenly lose control of the ship and crash into the ocean. Though he is able to communicate with Weir (Torri Higginson) he soon loses contact with Atlantis as he sinks lower and lower. Trapped in the back of the ship with almost no power and a badd concussion McKay begins to hallucinate. Fortunately for him his hallucinations come in the form of his intellectual rival Samantha Carter (Amanda Tapping) who is ready to assist him in finding a way out. However before they have time to formulate a plan t he jumper descends to the ocean floor and the impact causes a small break in the ship's hull allowing water to sink in. Meanwhile back on Atlantis Weir and Sheppard have located McKay and devise a plan to rescue him -- but will they reach him before time runs out?

Episode 15 - The Tower

During a trade mission on a distant planet the team is introduced to a village with a central tower -- one almost identical to the central spire of Atlantis -- inhabited by the village's revered leader who is able to protect the people that live there from the Wraith. Intrigued the team inquires about meeting this Lord Protector but the overly suspicious guards surrounding the tower capture Sheppard (Joe Flanigan) and confiscate the others' weapons. 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.

Episode 16 - The Long Goodbye

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!

Episode 17 - Coup D'etat

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.

Episode 18 - Michael

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.

Episode 19 - Inferno

Episode 20 - Allies

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.
