Turlough reveals exile and Trion connection

Turlough breaks his silence to expose the truth of his exile and the Sarns' tragic plight. In stark contrast to the Doctor's immediate concern for the planet's stability, Turlough reveals the Misos Triangle as the mark of a prisoner, forcing a reckoning with the planet's purpose as a prison colony for Trions. He implicates his father's fate, connecting his own survival to the Sarns' struggle and seeding moral justification for the Doctor's intervention. The revelation reframes the conflict beyond planetary survival to include existential justice, deepening the stakes for all parties involved.
