Detonator's Waxed Cartridge
The Doctor, in a radiation suit, unscrews the detonation unit's inspection cover inside the atomic fuel store and extracts this waxed cartridge. Wires connect it directly to the radio control box. He handles it with steady precision as Madeleine counts down from 11:55, while Jamie, Zoe, and Milo watch tensely outside, fearing a wrong move will trigger catastrophe.
