Internally frustrated by Turlough’s evasiveness but outwardly probing with relentless logic

The Doctor kneels by the glowing cave walls, brushing the blue deposits with his fingers while engaging Timanov about the flame’s significance. He presses Turlough relentlessly for answers about the control center’s maintenance, Trions, and his father—linking every clue to the Master’s scheme. His tone is both investigative and combative.

Goals in this moment
  • Confirm whether Turlough is withholding critical information about Trion or the Master’s operations
  • Establish the true nature of the blue flame through scientific analysis of cave deposits
  • Prevent the Sarns from being misled by a false deity into aiding the Master’s agenda
Active beliefs
  • The blue flame is unnatural and likely manipulated by the Master to control planetary energy
  • Sarn’s control systems and colonial ruins hold keys to understanding and stopping the Master’s plan

Feigned indifference masking sharp defensiveness and latent fear of exposure

Turlough stands between the Doctor and Timanov, interpreting the blue flame’s reappearance as Master-induced rather than divine. He answers the Doctor’s questions with deliberate vagueness, redirecting focus toward the Hall of Fire while sidestepping inquiries into his father’s past and Trion heritage. His tone is pragmatic and guarded.

Goals in this moment
  • Avoid revealing his Trion connection or the significance of the Misos Triangle
  • Control the Doctor’s access to critical information about the control center and his father
  • Keep the Doctor’s attention focused on immediate threats (the blue flame, the Master) to prevent deeper questioning
Active beliefs
  • The Doctor’s pursuit of truth about Trion or the control system is dangerous and must be curtailed
  • The blue flame signals manipulation by the Master and destabilizes the fragile alliance between the Doctor and the Sarn people

Reverent conviction tinged with urgency to act on what he perceives as divine mandate

Timanov stands before the blue flame, reciting its sacred significance to his people without physical action beyond declaration.

His presence underscores the religious dimension clashing with scientific inquiry.

Goals in this moment
  • Galvanize the Sarns to worship, reinforcing belief in Logar and deflecting questions about the world’s instability
  • Affirm the flame’s signaling of recovery and renewal for the sick and injured
Active beliefs
  • The blue flame is a sacred sign from Logar promising healing and mercy to the Sarn people
  • Any deviation from this truth is heresy and threatens the moral and social order of Sarn

Key Dialogue

"DOCTOR: I wonder if Logar will help a sick Time Lord. Perhaps the Master needs the blue flame more than the people of Sarn."
"TIMANOV: It's a sign of great favour from Logar. He's showing his mercy to the sick and the injured. There'll be a gathering. We must go to our people."
"DOCTOR: If this is an abandoned planet, what was your father doing here?"
