Great One breaks Doctor's will

The Doctor arrives in the Crystal Cave expecting Sarah’s distress call to be genuine only to suffer a devastating realization—Sarah’s voice was an illusion masterminded by the Great One. The cosmic spider reveals her true form and accelerates her domination over the Doctor, stripping away his autonomy through relentless mind control. Under the Great One’s escalating demands, he is forced to betray his own judgment and step toward compliance. With her advantage secured by the stolen crystal and his free will mortgaged, the Great One’s authority becomes absolute and Earth’s fate is placed in grave jeopardy. key_dialogue: [ GREAT ONE: You are proud, little man. I see that I shall have to teach you to have respect. Round you go, Doctor. DOCTOR: (Against his will, the Doctor turns left, stepping high, as the Great One laughs.) No. No! No, I will not! DOCTOR: (The Doctor has turned right round and back to where he started.) No! No, I will not! No! ]
