Summary

With information on the location of all thirty-seven Aurora-class Replicator vessels in the galaxy, the expedition begins planning for a means to stop the Replicators from destroying more human worlds. They've also begun evacuating planets in the path of the Replicators. The Daedalus and the Apollo and their captains, Col. Caldwell and Col. Ellis have arrived at Atlantis to provide support and have upgraded their weapons with plasma beam technology.

Though impressed by his own progress, McKay and his Wraith partner have not found a way to shut down the replicators. Ellis is angered by what he sees as McKay's wasting of their time but Colonel Carter chastises him for his rudeness and threatens to revoke her hospitality. The Colonel's fallback plan is to destroy each replicator ship with their weapons but McKay argues that merely leaves Replicator cells inert not destroyed. His method, should it work, would wipe them out completely. He requests more time to work on it. Carter gives him ten hours.

Hours later, McKay is still stalled and plan B is put into action. The Daedalus and Apollo manage to destroy a Replicator vessels easily. A week later, several more vessels are destroyed and the Replicators fall back to their homeworld to formulate a new strategy and build more ships. Ellis sees potential to wipe them all out at once but the task is too great for only two ships. The team has approximately a week to come up with a new strategy of their own before the Replicators separate and head back out into the galaxy.

McKay still has no luck with shutting down the nanites. After contemplating using the Ancient anti-replicator technology to which the Replicators are likely immune, McKay hits upon a new solution. Rather than severing the connection between individual nanite cells, he wants to increase their attraction significantly. All nanite cells would be drawn together to the replicator homeworld, forming a superdense blob. Sheppard questions the possibility of creating one super replicator but McKay insists the nanite cells would need more time to adjust to their situation before they fuse too tightly together and become inert. Carter believes his idea may have potential.

To complete the task, McKay plans to use the same machine the Ancients used to develop the Replicators. He wants to create a block of nanite cells that will spark the attraction to the other replicators. His initial attempts fail, however, as the machine was not designed to make blocks of nanites, but human form replicators. The idea is to visit the replicator homeworld, beam the blocks into a populated area and activate its programming. McKay then realizes that though the Replicators on the planet will immediately be affected, those in orbit will have time to escape unless they can formulate a distraction.

They face a problem providing such a distraction as they are hopelessly outnumbered. Sheppard has an idea to get more ships however. They ask their Wraith prisoner for his help getting the cooperation of the Wraith and he agrees. Their Wraith must personally negotiate with others. Sheppard and his team visit the Wraith vessel where they are all stunned by the Wraith. When they awaken the deal is complete and they have gained the cooperation of seven Hives. It is not the twelve they were hoping for but without Queens some vessels fear they won't be able to replenish their numbers.

On their way back to Atlantis, the team runs into an Aurora-class vessel captained by Larrin. She intended to investigate the meeting of several Wraith vessels. The team manages to negotiate for her people's help in their plan. On their return to Atlantis, Teyla decides to check in with the infirmary, surprising both Sheppard and Ronon. She reveals she is three months pregnant and has known for almost two months. Sheppard is extremely angry with her for the risk she's taken and removes her from active duty immediately. Ronon however, is more supportive realizing the child's father is among the missing Athosians and assures her they'll find him together.

After several failures getting the nanite blocks to maintain cohesion, McKay decides to create a human form replicator, which was the real purpose of the machine. He names his creation FRAn (Friendly Replicator Android). FRAn has all the intelligence of her brethren but is willing to go along with McKay's plan. She finds that his calculations may be slightly off. She estimates the nanite cells will adapt faster to their circumstances than he believed. The mass will be able to manipulate itself before reaching critical mass and stop the process. She has a solution however, overloading the ZPMS around the mass causing them to be further compressed and ultimately destroying the planet. To do that, McKay, Ronon and a team of marines will need to beam down to the planet to overload the ZPMs. Sheppard will operate the chair on Larrin's ship.

The plan goes into action and the Travelers, Daedalus, Apollo and several hive ships head for the Replicator homeworld. FRAn reveals that she's excited about their plans and not at all concerned about her soon to be nonexistence. She wishes him luck on his mission. Both are beamed down to the replicator homeworld to begin their respective missions. In orbit, the battle ensues and several Wraith, and Traveler vessels are destroyed.

McKay completes his action and FRAn activates. The replicators are drawn to her, on the planet and from space. The nanites form an enormous mass on the planet. McKay is unable to set the ZPMs to overload as the mass has interrupted power systems causing a blackout. They are running out of options but Carter realizes that the city rests on a vast deposit of naturally dense neutronium. McKay can increase the attraction between the cells so they attract the neutronium increasing the density and causing the mass to sink to the planet's core where the pressure will increase significantly, resulting in an implosion that will destroy the replicators and the planet. The plan succeeds and the fleet leaves the system.

McKay deletes the Replicator homeworld M7R-227 from the database.

Back in the Replicator system, a ship is seen in the system checking for trace replicator cells. None are detected. A woman in black who appears to be Elizabeth Weir states that they can finally get to work without looking over their shoulders.
