Distressed Research Rats

Four cages hold small, frantic rodents whose unnatural distress produces sickly violet soliton fumes—an acrid, ozone-tinged haze that curls up from the wire floors. Their rapid breathing and darting movements reflect the same time-manipulating technology built into the cellar’s hidden regulators, turning them into walking gauges of experiment failure. Tegan’s sack lifts to uncover their suffering, while the Doctor waves the concern away as routine ‘research,’ though the rats’ unnatural byproducts contradict his dismissal.
