Prime Target: Why Did Adam Betray Edward and Hand Him Over to Axiorn?

Spoiler warning: this article covers major plot developments from episode 7 of Prime Target, including the death of a recurring character.

Adam Mellor (Fra Fee) was an Axiorn operative from the beginning of the series. In episode 7, Andrew Carter (Harry Lloyd) makes that explicit on screen: Adam was assigned to monitor Edward Brooks (Leo Woodall) from the start of the series, before any romantic connection between the two had developed. The relationship was a surveillance operation. Axiorn needed someone close enough to track Edward’s progress and move at the right moment.

How Adam Delivered Edward to Axiorn

After Edward resurfaces from hiding, Adam offers him somewhere to stay at his aunt’s flat in East London, framing it as a safe location where he can continue his work. Edward, who has been running on almost no trust, accepts. Adam drives him there. As they arrive, Axiorn operatives move in, sedate Edward, and take him. The episode gives that moment no drama: Adam sits motionless and watches.

The episode offers no dialogue to explain it; the reading the scene invites is that Adam had already settled the question before they arrived.

What Axiorn Actually Wanted

Axiorn’s goal, as Carter explains it to Edward inside the facility, is to hold the prime finder technology rather than deploy it, keeping the United States ahead of any foreign actor who might develop it independently. The funding chain runs from Axiorn to Kaplar to the NSA. Jane Torres (Martha Plimpton), the NSA figure overseeing the operation, tells Edward the agency has no intention of deploying the prime finder against civilian infrastructure.

Carter’s pitch to Edward runs along the same line: complete the prime finder under Axiorn’s supervision and no one else can use it against the world first. He describes Axiorn as “basically the good guys.” The episode does not supply enough evidence to confirm that characterization, and Edward does not accept it. The series finale reinforces how hollow it was: Carter ends up leading the NSA investigation into the very events he orchestrated, while Axiorn itself faces no immediate accountability.

Edward’s Specific Words for Adam

When operatives drag Edward away from Adam’s car, he turns to Adam and uses two words: “nothing” and “zero.” Both are mathematically precise insults from a man whose entire frame of reference runs through numbers. The series has established Edward’s relationship with zero as a concept with genuine significance to him. Our reading is that deploying it as contempt inverts the significance the series attached to zero as a concept. If that reading holds, it is the clearest signal the episode gives that the betrayal has reshaped how Edward relates to his own work.

The episode does not follow that with speeches or tears.

Professor Osborne, the Formula, and the Escape

Inside Axiorn’s facility, Carter brings in Professor Raymond Osborne (Joseph Mydell), Edward’s former mathematics teacher, to assist with the prime finder formula. Together, Edward and Osborne advance the work far enough to complete it. Taylah Sanders (Quintessa Swindell), the NSA field agent who has tracked Edward’s research since the opening episodes, agrees to code the theorem after Jane Torres makes Axiorn’s pitch to her.

The escape Taylah engineers does not go cleanly. She disables facility security using a hidden application and knocks Carter out with a fire extinguisher. During the attempt, Carter recovers and threatens to shoot Edward unless he hands over his notebook. Osborne steps in front of Edward. Carter shoots him, and Osborne dies at the scene. Taylah pulls Edward out.

One secondary source, DM Talkies, refers to the finished formula as the “Brooks-Osborne theorem.” The show itself uses the term “prime finder” throughout.

Whether Adam’s Feelings Were Real

Adam tells Edward that his feelings were genuine. That is the one claim the episode leaves open. Carter’s confirmation that Adam was assigned before the relationship developed makes clear the connection was not spontaneous. What cannot be determined from the episode is whether Adam developed real attachment alongside his assignment, or made the claim only to soften what he had done.

The show does not settle the question. Our reading of that image is not charitable to Adam: he sits motionless in a car as men sedate the person he claims to have cared for. What the confirmed facts do establish is that Axiorn held direct access to Edward’s movements, his emotional state, and the arc of his research across the full run of the series. The vulnerability was not his mathematics. It was the trust he placed in someone who was, at minimum, never only his boyfriend.
