Turlough rejects darkness to destroy the Black Guardian

The White and Black Guardians arrive in the stateroom to claim their prizes, the Black Guardian believing he can turn Enlightenment to his dark ends. When the White Guardian offers the diamond to Turlough as a reward for his assistance, the Black Guardian immediately tempts Turlough with the Doctor's life and the TARDIS in exchange for the crystal. In a moment of moral clarity, Turlough seizes the diamond and hurls it at the Black Guardian, destroying him in a burst of flames. He then casts his own black crystal into the fire, ending his corrupt pact. This confrontation forces Turlough to choose between darkness and light, revealing his redemption and severing the Black Guardian's hold over him permanently, though the White Guardian warns that the cosmic battle is far from over.

Key Dialogue

"BLACK GUARDIAN: I would point out that under our agreement, it is mine. Unless, of course, you wish to surrender something else in its place. The Doctor is in your debt for his life. Give me the Doctor, and you can have this, the Tardis, whatever you wish."
"WHITE GUARDIAN: Consider, Turlough. Which will you give him? The Doctor, or this? The choice is yours."
"TURLOUGH: Here, take it!"
