Device detects energy absorbing pebble

The fist-sized pebbles, hastily gathered from the jungle floor, become the focus of the Doctor’s final gamble. Their irregular shapes and red-silt coatings make each one a potential key; the Doctor’s deliberate selection and steady scanning transform them from inert debris into surgical tools against the spider menace. The pebbles jostle faintly in his robes, their latent significance only revealed by the scanner’s response.

The compact scanner, its single display light flickering erratically, becomes the instrument of salvation. Held in the Doctor’s unsteady grip, its readings guide every agonizing selection of pebble after pebble. On detecting the third stone, the device emits a high-pitched squeal and grows warm, marking the transition from futile search to actionable insight. Its noisy affirmation breathes fragile hope into the hut’s choked atmosphere.

The timber-framed meeting hut serves as the fragile nerve center for the village’s rebellion, its soot-blackened beams and single iron-braced window framing moments both mundane and dire. In this event, the hut’s dim hearth light illuminates the Doctor’s failing body and the small, hopeful glow of the scanner, casting long shadows that seem to underscore every flicker of hope or flicker of doubt. Here science and superstition collide under the same roof.
