Jack comes up with a plan to destroy this new strain. Mae and Jack drink vials containing a form of phage that kills the nanobot-producing "E. coli" bacteria and thus would protect them from infection by the nanobots. Jack then proceeds to take a sample of the phage and pour it into the sprinkler system and drench everyone with it. He has Mae alert Julia and the infected team. They set out to stop Jack. In the vicious struggle that ensues, Jack is captured and thrown into a magnetic chamber, with Ricky threatening him to either reveal his plan or be killed by the magnets. Jack feigns surrender when Julia walks in to interrogate him, but Jack then reactivates the magnetic chamber with Julia inside, remembering the incident with Amanda in the MRI. Julia's body disintegrates as a swarm is pulled away by the magnetic field to temporarily reveal the real Julia, who has slowly been consumed by the parasitic swarm. Before the swarm can repossess her body, Julia begs Jack to forgive her for putting him in danger, says she loves him, and tells him to stop the swarms and save their children from the same fate, as they have been infected too. Motivated, Jack runs to the roof, fights off the infected team, and finally manages to place the sample into the sprinkler system.
