Turlough seals his pact and vanishes

The Black Guardian pressures Turlough to finalize their deal, dangling freedom from his wretched schoolboy life if he will only agree to murder the Doctor. Turlough resists briefly, horrified by the act, but his desperation trumps principle—when forced to choose between Earth and the unspeakable crime, he begs for exile rather than return. His ascent into the Guardian’s power is immediate; the moment he consents, his form dissolves into the void, leaving only the Guardian’s mocking laughter behind. The bargain is struck, and Turlough is gone, his fate now bound to the sinister entity’s will. key_dialogue: [ GUARDIAN: We haven't much longer. I need to know that I have your assent to our arrangement. You will find me the most accommodating of partners. TURLOUGH: Yes. GUARDIAN: Yes or no? TURLOUGH: Yes. ]
