Doctor exposes Fendahleen energy source

The Doctor seizes the moment after his companions break free from the Fendahleen’s telekinetic hold to reveal the creature’s true nature as a parasitic entity sustained by raw human energy. Drawing the connection to Thea’s ongoing transformation and the skull’s restructuring of her brain, he explains how the Fendahleen formed from pure energy, its very existence tied to the skull’s power. The revelation reframes the immediate threat as both imminent and escalating, warning that the Fendahl’s formation remains incomplete and its destructive potential grows with each passing minute. Tyler’s confusion underscores the gravity of the discovery, while the Doctor spots an exposed power cable leading toward the cellar, hinting at the deeper machinations already unfolding below. key_dialogue: [ DOCTOR: It was a Fendahleen. It was the same thing that killed the hiker and Mitchell. It can only have been created out of pure energy while the skull was restructuring Thea's brain. DOCTOR: That's it! Leela, you'd better come with me. ]
