Cyber Leader reveals deadly countdown betrayal

The Cyber Leader’s true malicious intent is laid bare as their subordinate reports rising radar distortion that blocks tracking of the human bomb carriers. Rather than addressing the flaw, the Cyber Leader coldly dismisses its relevance while revealing a hidden mechanism: the bombs are wired to detonate the moment the countdown hits the red zone, ensuring the carriers die before escaping. This brutal calculation exposes the Cybermen’s willingness to sacrifice collaborators and Sarah Jane to guarantee Voga’s destruction, escalating the Doctor’s ticking-clock crisis. The Doctor and Sarah Jane, who have begun working against the Cybermen’s plan, now face an even narrower window to subvert it. key_dialogue: [ LEADER: That is of no importance now. Even the Doctor believes they will be given time to escape before our bombs explode. They do not know the detonators will fire when the countdown enters the red zone. ]
