Jellicoe's Sabotage Screwdriver

Jellicoe uses the Jellicoe's Adjustment Screwdriver to make final mechanical adjustments to the robot’s joint interface after reattaching the head unit. He grips it firmly during minute calibrations on the newly reactivated systems, ensuring the machine’s limbs move correctly, stabilizing at one point with a vertical left arm raise.

Jellicoe uses the worn plastic-handled screwdriver during the head reinstallation phase, making fine positional adjustments to the robot’s cranial assembly. Once the unit is secured, the tool is set aside as he steps back, leaving both object and creator morally compromised by the subsequent weaponization sequence.

The Doctor uses this mechanical screwdriver to melt the rock-mounted forcefield plate securing the apparatus holding Sarah captive. Once melted, the forcefield collapses, freeing the Doctor to physically snatch the device and shelter Sarah.

The adjustment screwdriver is used by the Doctor to melt the forcefield plate, enabling his approach toward Styre and advancing the confrontation. It acts as an improvised tool of disruption against Sontaran technology.

The Doctor hands the screwdriver to Harry with explicit sabotage instructions and a clandestine mission plan. This otherwise mundane tool becomes a chit of trust, shifting from standard UNIT issue to a vector of hope—empowering Harry to infiltrate and disable Sontaran systems deep inside the enemy’s own vessel.

Jellicoe’s Adjustment Screwdriver, handed to Harry by the Doctor moments before the gravity crisis erupts, becomes an instrument of misdirection rather than direct sabotage in this event. The Doctor uses it not to break the gravity device but to transfer Harry’s attention away from action and toward the rescue effort. Its presence symbolizes human ingenuity repurposed under alien duress.

Transferred by the Doctor into Harry’s hands just before the duel commences, the screwdriver immediately becomes a tool of sabotage, symbolizing the Doctor’s dual objective: distracting Styre while enabling direct action against his ship. The metallic tool’s sharp tip and hexagonal shaft fit Sontaran mechanical interfaces, making it immediately serviceable for disabling forcefields or controls.

The Doctor employs the Jellicoe screwdriver to probe the locked Q section door mechanism, testing for weaknesses and seeking a means to bypass the temporal sabotage preventing normal operation. Its worn brass shaft becomes an instrument of desperate ingenuity, signaling their constrained agency in the infected station's altered timeline.

The Doctor uses his sonic screwdriver to breach the locked cabin door and probe the mechanism, revealing the hidden compartment where Kellman’s transmitter and gold pouch are stashed. The screwdriver’s use exposes the villain's secrets and enables the Doctor’s survival.

The Doctor uses Kellman’s sabotaged Jellicoe’s Sabotage Screwdriver to break into the locked cabin and probe the disguised hairbrush and hidden transmitter. It functions as both a tool for infiltration and a catalyst for exposing Kellman’s deception through subtle mechanical evidence.
