Corridor Leading to Trapdoor

Ben points to this narrow corridor branching from the Tracking Room, urging a sprint to the trapdoor at its end. He plans to bolt it shut behind them, blocking Cybermen pursuit from the Snowcap base. The Doctor dismisses the route as useless against their strength. Metal walls likely press close, lights buzz overhead, and cold air carries distant machinery hum—spaces of fleeting hope crushed by alien dominance.
