Why This Matters Across Episodes
The longer arc this connection carries
The Brigadier's decision to extract Captain Turner under extreme duress in Episode 17 establishes the military's immediate responsiveness to UNIT's precarious positions. This sets up the helicopter transport in Episode 18 that delivers the Doctor and allies directly to the Cybermen compound, catalyzing the confrontation.
