1x3 - The Prisoner

2 offers 6 the opportunity to become an undercover agent, spying on suspected dreamers. 6 accepts with ulterior motives. He works with 909, who is spying on him. 6 follows 909 into the Go Inside bar, where he finds him meeting with his secret lover, 11–12. Rather than allowing the relationship to be discovered, 11–12 kills 909. 6 blackmails 11–12 to help him rescue 313, who has been captured and sent to the clinic.
