Four Flares in the Box

Four magnesium flares remain in an intact box during the lighthouse siege, rescued from earlier chaos. Their bright white light could serve dual purpose—either as a distress signal against the encroaching Rutan forces or as a weapon through concentrated flare-induced glare. The Doctor, Leela, and Skinsale all note their potential with urgency, suggesting these mundane survival tools have become the key to Earth's last hope: transforming the lighthouse beam into a weapon against the alien threat.

Before: Concealed within Palmerdale's body as his 'insurance' against political downfall, the diamonds' true purpose unknown to everyone present

After: Extracted with bloodied hands and destined for immediate deployment into the carbon arc beam mechanism

Four magnesium flares stored in a box are noted by the Doctor as potential tools, though their use is deferred for later stages of the plan. Their bright white light could either signal for help or, as later realized, be integrated into the carbon arc beam’s transformation.

Before: Intact and untouched in the lamp room box

After: Still unused, reserved for the emergent carbon arc weapon plan
