Doctor finds Nyssa missing during escape

The Doctor drops to the floor and wriggles out under the wedged chair into the corridor beyond, expecting to lead Tegan to safety. He turns back only to realize Nyssa is no longer behind him, her absence striking like a blunt instrument. The realization hits just as their margin for error vanishes; the liner’s containment systems begin their calm, methodical purge of the infected corridor. Time fragments into instants of dread—calling out to Tegan now risks drawing every wandering lazar in the ship to their exact location.
