Doctor and Sarah escape bonds while contacting Stevenson

The Doctor and Sarah struggle against bonds in the Secondary Control Room as the Nerva Beacon’s collision course nears urgency. Using deft knot-work skills reminiscent of Houdini’s techniques, the Doctor frees both of them. As Sarah confirms their freedom, the Doctor seizes the moment to contact Stevenson on Voga, revealing the Cybermen’s abandonment of the Beacon and issuing a critical command to redirect the Vogan rocket away from the Cybermen toward their cybership. Time is running out, and every second counts in tipping the balance against the Cyber Leader’s plan. key_dialogue: [ DOCTOR: Hmm? I used to untangle Turk's Head eye-splice with the grommets I picked up from Houdini. It should work. SARAH: Really. Well, you must have tied it wrong. No, wait a minute. You're right, they're loosening! DOCTOR: (They are both free of the ropes.) Good girl. That rocket's getting too close for comfort. DOCTOR: Hello, Voga. Hello, Voga. This is Nerva Beacon. STEVENSON: ([OC]) Doctor, is that you? DOCTOR: Commander, tell Vorus the Cybermen have abandoned the beacon. He's to aim the rocket at the cybership. ]

Cybermen Restraint Ropes

The thick, coarse Cybermen restraint ropes initially bind the Doctor and Sarah tightly, immobilizing them in the Secondary Control Room. As the Doctor works the Turk’s Head splice with the grommets, the ropes gradually slacken and slide apart, allowing escape—just as the Nerva Beacon’s collision course intensifies.

Before: Tightly knotted and immobilizing both captives, frayed slightly from previous tension, lying across consoles and wrists in painful strain.
After: Loosened and slack, slipping apart without noise as the Doctor frees his and Sarah’s limbs, leaving them coiled near the control panel.
Doctor's Nerva Station Emergency Comms Unit

The jury-rigged Doctor’s Nerva Station Emergency Comms Unit is central to the event, enabling the Doctor to establish contact with Stevenson on Voga seconds after his liberation. He works its mismatched switches and exposed wiring under urgent radio static to convey the lifesaving redirection order.

Before: Mounted near the control panel in the cluttered Secondary Control Room, functioning despite visible makeshift modifications and incomplete calibration.
After: Still active, now transmitting the Doctor’s revised targeting command to Vorus via Stevenson, its signal slicing through cosmic interference with growing clarity.
Houdini's Turk's Head Grommets

The Doctor uses the two Houdini-style Turk’s Head grommets as precision tools to thread through the rope weave, leveraging his knowledge of knot-disentanglement to methodically loosen the Cyberman restraints despite Sarah’s initial skepticism.

Before: Carried by the Doctor, presumably hidden or at hand, their brass surfaces worn from prior use but clean and ready.
After: Still gripped in the Doctor’s fingers as he finishes the escape, one grommet may bear a trace of rope fiber, now set aside once the knots yield.
