Stegosaurus blocks UNIT’s path to Moorgate

The Doctor and Brigadier Lethbridge-Stewart arrive outside Moorgate Station to intercept Finch and Grover’s temporal reset but find their path blocked by a prehistoric stegosaurus. Realizing the creature is unharmed and simply occupying the entrance, the Brigadier acts decisively, throwing a grenade to scare it away. The explosion forces the animal to retreat, clearing a vital route for the mission. The moment highlights the Brigadier’s willingness to make hard choices under pressure, even when those choices involve force, and underscores how even minor disruptions can threaten the success of their critical mission. The stegosaurus serves as an unexpected obstacle, forcing the team to adapt their plan in real time and reinforcing the precarious nature of their undertaking. key_dialogue: [ BRIGADIER: Quick, take cover! ]

Causal medium

"The Doctor and Brigadier's use of explosives to clear a stegosaurus from the Moorgate Station entrance parallels the later use of explosives to blast open the hidden passage to the control room. Both moments show tactical ingenuity under environmental and temporal pressure."
