Doctor sacrifices Malkon for cosmic battle

With Malkon collapsing from his affliction, Turlough urgently seeks to evacuate him to the TARDIS for treatment. The Doctor refuses, his cold rationale revealing a brutal calculus: the immediate survival of one man weighs nothing against the cosmic threat posed by the Master and the strategic value of Sarn’s numismaton gas. His detachment shocks Turlough into protest, but the Doctor remains fixed on commanding the Hall of Fire’s energy flow to confront the greater enemy. This moment fractures the Doctor’s reputation with his companions, exposing the cost of his mission-driven resolve.
