Turlough abandons group to seek escape route

Turlough seizes a moment of perceived opportunity and abandons Tegan to search alone for an unguarded exit back to the space liner. His action fractures the companions' fragile trust and forces Tegan into a liminal space of uncertainty, while the station's unstable environment amplifies the cost of his individual gamble. Though Turlough claims the mission as a practical necessity, his unilateral decision reflects a deeper mistrust and self-preservation that begins to isolate him from his allies in their final push to survive Terminus. key_dialogue: [ TURLOUGH: There must be a way to recreate the door we entered this ship by. Wait here. ]
