Unicorn dissolves through disbelief

In a void of darkness, Jamie and Zoe confront a monstrous unicorn—an embodiment of Jamie’s recurring nightmare—charging toward them with terrifying force. Jamie, paralyzed by fear, insists they run, while Zoe confirms its reality, both reinforcing the creature’s power through their belief. The Doctor intervenes, gripping their wrists and commanding them to reject the unicorn’s existence. As Jamie and Zoe repeat 'It doesn’t exist,' the unicorn halts mid-gallop and collapses into a harmless cardboard cutout. The Doctor immediately identifies this as a test, explaining that their belief in the unicorn’s reality made it dangerous, while disbelief neutralized it. Jamie questions the logic, but the Doctor theorizes a 'fantastic mind' is orchestrating these illusions, setting up the Master as the unseen architect of their trials. The scene underscores the Doctor’s intellectual dominance in this reality, where perception dictates survival, and foreshadows the Master’s psychological games ahead.
