Drathro names the Doctor his heir

As Katryca’s villagers close in on the castle, Drathro and his assistants grapple with imminent annihilation. When Humker questions the futility of defending against the attack, Drathro reveals his contingency plan—naming the Doctor his successor. It is a moment of cold pragmatism, stripping away any pretense of morality as Drathro chooses a replacement he barely knows to preserve his research at all costs. The exchange underscores his ruthlessness and the Doctor’s entanglement in a conflict far beyond his original mission.
