Flasks of Rock Salt

Thick glass vials stoppered with corks, each cradling pale, crystalline grains of rock salt. Leela loads a trolley with a dozen flasks before the final confrontation, their contents meant to blunt the Fendahl's energy absorption. The salt retains its coarse texture, visible even in dim lab lighting, a mundane material elevated to supernatural defense against an unstoppable entity.

Salt arrives as Tyler exits under protest

The nine flasks of rock salt, sealed in glass with cork stoppers, comprise the core of the Doctor’s mundane-yet-supernatural defense strategy. Transformed from kitchen staple to explosive payload, their coarse crystals represent the team’s last stand against an entity that drains souls, ready to be deployed in precise geometric patterns.

Before: Resting in Martha’s trolley pouches, sealed and clustered during lab logistics.
After: Loaded into Leela’s basket, becoming active components in the catastrophic implosion sequence.

Leela and the Doctor race against the clock

Before: Delivered in sealed glass bottles by Martha, later transferred into the wicker basket for ease of transport.
After: Carried by Leela into the cellar, designated for geometric deployment around the skull during the Doctor’s coordinated plan.

Doctor seals Fendahl skull in radiation box

Flasks of rock salt are used by Leela and the Doctor as improvised weapons against the Fendahleen. Though their aim is poor, the act demonstrates tactical resourcefulness—applying a known weakness of the Fendahl’s energy absorption to create disruption. They serve as both physical projectiles and symbolic resistance against the creeping horror rising from below.

Before: Stored and readily available in quantity on a nearby trolley or altar surface
After: Partially emptied, tossed at the creature, and left scattered in the chamber as the focus shifts to skull containment
