Doctor fires lighthouse weapon at alien ship

The Doctor takes control of the lighthouse lamp’s reflector mechanism, manually orienting the powerful beam toward the hovering Rutan mother ship. With Leela’s help, he prepares to activate the weapon as the alien craft tightens its orbit over the sea. Recognizing the immediate danger of the antihuman beacon still being transmitted, the Doctor seizes the chance to strike first, prioritizing the destruction of the mothership over retreat. The countdown begins as the Doctor orders Leela to flee, emphasizing that survival is now the only viable objective. Running down the stairs with the lamp’s energy whining to critical mass, he refuses to let hesitation dictate their fate. key_dialogue: [ DOCTOR: It is. When it gets within range, this will lock onto its carbon resonator and knock out its anti-grav, I hope. We've got about a hundred and seventeen seconds to get out of here. Understand? LEELA: Perfectly. DOCTOR: Good. So when I switch on, you run for it, all right? ]
