TARDIS Crew's Cabin

Barbara and Susan enter the cabin assigned to the TARDIS crew, where a disoriented man shuffles toward them before collapsing at their feet. The shock drives their retreat into the adjacent corridor, but the hatch jams shut, locking them inside the spaceship's hostile confines. They duck into a nearby storeroom, the cabin's tight space amplifying the intrusion's terror and exposing the ship's failing systems under Sensorite influence.
