Sabotage exposed in the ops room

The Doctor confirms the explosives' 60-second timer to Colonel Lethbridge-Stewart, but the moment is shattered when Staff Arnold reports the unsecured main door—a critical breach in their defenses. Before the team can process this, Blake arrives with the padlock from the explosives store and the missing Yeti model, both found together. The discovery forces the group to confront the reality of internal sabotage, with the Doctor’s earlier plan to blow the tunnel now compromised by an unseen traitor. The tension escalates as the Colonel and Knight react with urgency, while the Doctor’s focus shifts from tactical execution to identifying who among them is aiding the Great Intelligence. The scene fractures the team’s cohesion, replacing military discipline with suspicion and forcing a reckoning over trust at a critical juncture in the battle against the Yeti and the spreading web.

Goodge Street Baggage Trolley

The baggage trolley is mentioned by Arnold as being prepared for the explosives plan, intended to serve as a mobile platform for the 60-second timer devices. Its role is to provide a means of transporting the explosives down the gradient without direct human contact, minimizing risk. However, the discovery of the sabotaged padlock and Yeti model raises questions about the trolley’s safety, as the explosives store—where the charges were likely stored—has been compromised. The trolley’s readiness is now overshadowed by the larger crisis of internal sabotage.
