Doctor and Turlough search for Peri

The Doctor and Turlough press onward across the unstable terrain of the doomed planet, driven by a quiet but profound divergence in their assessment of survivability. While Peri’s recent desperate sprint suggests another survivor amid the volcanic chaos the Doctor dismisses outright the notion that anyone remains alive on Sarn. Turlough, however, defies the scientific certainty of the TARDIS’s prognosis with an instinctive conviction rooted in his evolving connection to the planet. Their exchange underscores a growing rift in trust—one that may soon demand personal sacrifice as they near the forbidden crash site and Kamelion’s rogue influence.
