Jo’s radio plea for UNIT backup

The scene erupts into violent chaos as the Doctor’s distrust of the Master triggers a physical confrontation. After the Doctor kicks the Master’s gun away, Jo—recognizing the escalating threat—immediately breaks protocol to radio the Brigadier for urgent UNIT intervention. Her frantic transmission, delivered in the midst of the hangar’s escalating crisis, underscores the severity of the situation: the Master’s nerve gas missile remains armed, the Keller Machine’s influence is growing, and the Doctor’s plan to negotiate with the Master has collapsed. The Brigadier’s response confirms UNIT’s readiness to act, but the moment also exposes the fragility of their operational cohesion under pressure. This beat serves as a critical turning point, forcing UNIT into direct action while reinforcing the high stakes—without coordinated intervention, the Master’s plan will succeed, and the Keller Machine’s malevolent influence will consume them all.

The Keller Machine doesn’t have emotions, but its throbbing suggests a predatory, almost hungry state. It’s as if it’s absorbing the negative energy of the confrontation—the Master’s frustration, the Doctor’s distrust, the urgency of the moment. Its passivity is deceptive; it’s a ticking time bomb, waiting for the right moment to unleash its full power.

The Keller Machine arrives in the Black Maria with Jo and Barnham, throbbing ominously on the ground near the Master after the Doctor disarms him. It remains a passive but deeply unsettling presence, its pulsations a constant reminder of the malevolent force at play. The Machine’s proximity to the Master and the armed missile amplifies the tension, as if it’s feeding on the chaos and violence unfolding around it.

  • Its presence will destabilize the situation further, making it easier to feed.
Character traits
Ominous (throbbing pulsations create a sense of dread) Passive (does not take direct action, but its presence is threatening) Feeding (seems to draw energy from the conflict and evil impulses) Unstable (its malevolence is barely contained)
Follow Keller Machine's journey

Cunning and threatening at first, with a surface confidence that masks his desperation. His dialogue is laced with smugness, but his underlying frustration is evident—he knows the Doctor is his only path to escape, and he’s willing to bluff to get what he wants. When disarmed, his emotional state shifts to shock and frustration, his body language (flailing on the ground) betraying his loss of control.

The Master arrives at the hangar carrying a gun, engaging the Doctor in a tense negotiation over the TARDIS dematerialization circuit. He threatens the Doctor with the weapon, his demeanor smug and calculating. When the Doctor kicks the gun away, the Master stumbles to the ground beside the throbbing Keller Machine, his confidence shattered. He flails on the ground, momentarily powerless, as the Doctor, Jo, and Barnham retreat into the hangar.

Calculating and cautious, masking deep distrust of the Master. His surface demeanor is lighthearted (miming 'Bessie'), but his actions reveal a sharp, tactical mind focused on neutralizing the threat. The moment of kicking the gun away is pure, adrenaline-fueled decisiveness—no hesitation, no regret.

The Doctor arrives in the Black Maria, engaging the Master in a tense dialogue while subtly positioning himself to disarm him. He feigns cooperation, mimes steering 'Bessie' to distract, and walks toward the missile to turn the Master’s back to the van. Seizing the moment, he kicks the Master’s gun away with a swift, calculated strike, then retreats into the hangar with Jo and Barnham as the Master flails on the ground beside the throbbing Keller Machine.

Goals in this moment
  • Disarm the Master to prevent him from firing the nerve gas missile.
  • Protect Jo and Barnham by ensuring their retreat into the hangar.
Active beliefs
  • The Master cannot be trusted, even in negotiation.
  • Physical confrontation is the only way to disrupt his plans at this moment.
Character traits
Strategic Deceptive (feigning cooperation) Decisive (kicks the gun away without hesitation) Protective (ensures Jo and Barnham retreat with him) Sarcastic (mimes 'Bessie' to mock the Master’s ignorance)

Follow Brigadier Alistair …'s journey

Vulnerable and detached, with a hint of underlying fear. His childlike demeanor is accentuated by the chaos around him—he doesn’t understand the full scope of the danger, but he senses it. His compliance with Jo and the Doctor suggests trust, but his blank expression reveals a deep unease, as if he’s waiting for the next instruction or threat.

Barnham arrives in the Black Maria with Jo and the Keller Machine, remaining passive during the Doctor’s confrontation with the Master. As the Doctor disarms the Master, Barnham is seen near the throbbing Keller Machine, his expression blank and childlike. He retreats into the hangar with Jo and the Doctor, his presence a silent reminder of the Keller Machine’s danger and the stakes of the conflict.

Black Maria (UNIT Prisoner Transport Van)

The Black Maria serves as the pivotal transport vehicle that delivers Jo, Barnham, and the Keller Machine to the hangar. Its arrival is the catalyst for the Doctor’s disarmament of the Master—the Doctor subtly positions the Master with his back to the van, then kicks the gun away as the Master’s attention is momentarily distracted. The van’s interior is dark and claustrophobic, amplifying the tension as the Keller Machine throbs ominously within. After the confrontation, the Doctor, Jo, and Barnham retreat into the hangar, leaving the Black Maria as a silent witness to the escalating chaos.

Jo Grant’s Nerve Gas Crisis Radio

Jo’s radio-telephone (R/T) is the critical communication device that escalates the stakes of the confrontation. As the Doctor disarms the Master, Jo immediately pulls out the radio and calls the Brigadier for UNIT backup. Her frantic transmission—'Hello, Brigadier? Jo Grant here. Over.'—underscores the urgency of the situation and forces UNIT into direct action. The radio’s crackling response from the Brigadier confirms that reinforcements are on the way, but it also highlights the fragility of the team’s position. Without UNIT’s intervention, the Master’s plan could still succeed, and the Keller Machine’s influence could consume them all.

Master's TARDIS Dematerialisation Circuit

The TARDIS dematerialization circuit is the bargaining chip at the heart of the Doctor and Master’s negotiation. The Master demands to examine it, believing it will secure his escape from Earth. The Doctor, however, refuses to hand it over, sensing the Master’s betrayal. The circuit’s presence—though not physically interacted with in this event—hangs over the confrontation like a sword of Damocles. Its potential to grant the Master freedom is the reason he engages in the negotiation at all, and its refusal to be surrendered is a key factor in the Doctor’s decision to disarm him.

After: Still in the Doctor’s possession. The negotiation over …
Before: In the Doctor’s possession, offered to the Master as a potential bargaining tool. The Master is eager to examine it but does not yet have it in his hands.
After: Still in the Doctor’s possession. The negotiation over the circuit collapses as the Doctor disarms the Master, and the circuit remains a point of leverage for the Doctor moving forward.
