Alternative Tunnel (Chorley's Potential Hiding Spot)

Narrow branch tunnel splits off from a dim tunnel junction deep in the London Underground. Evans urges a search here for the fugitive Chorley, convinced he ducked into its shadows, but the Doctor shuts down the idea to race toward Covent Garden and the TARDIS. Stale air hangs heavy with damp stone and distant fungal reek; unlit passages twist into darkness, amplifying group tensions as Yeti threats echo faintly. The rejected detour underscores fractured priorities amid the Intelligence's chokehold.
