S15E25 · The Invasion of Time Part 5

Borusa transfers the Great Key to the Doctor

In the Chancellory’s shadowed halls Borusa reveals the restricted history of the Great Key’s custody, exposing the custom that only a Chancellor and no president holds it after Rassilon. When the Doctor demands to know who truly guards the Time Lords from tyranny the Chancellor admits the truth by producing the Key. The Doctor’s brutal readiness to kill Borusa to prevent Sontaran seizure underscores the Key’s lethal stakes, but Borusa instead places it in his hands—a ritual transfer of authority that makes him the first president in millennia to wield Rassilon’s entrusted power.
