Haunting visions precede Doctor’s change

The Doctor and Peri collapse into the TARDIS after escaping Jek and Morgus. Weakened by poison and bearing the weight of his friend’s survival, the Doctor collapses as Peri tries to revive him with the last of the bat’s milk. As he drifts toward death, hallucinations of his past companions—Adric, Nyssa, Tegan, Turlough, and Kamelion—circle around him, urging him to endure. The Master’s mocking laughter cuts through the pleas, his taunt a bitter mirror of the Doctor’s mortality. In this delirium, the Doctor’s form shifts, his regeneration beginning even as Peri cannot yet see it. The visions are both comfort and accusation, forcing him to face his legacy and the cost of every parting. key_dialogue: [ DOCTOR: Is this death? PERI: Don't give up. You can't leave me now! DOCTOR: I might regenerate. I don't know. TEGAN: What was it you always told me, Doctor? Brave heart? You'll survive, Doctor. MASTER: No, my dear Doctor, you must die! Die, Doctor! Die, Doctor. Bwahahahahahaha! PERI: What's happened? DOCTOR: Change, my dear. And it seems not a moment too soon. ]
