Why This Matters Across Episodes
The longer arc this connection carries
The Brigadier's capture of the Doctor and Jamie sets the stage for their coerced interaction with Vaughn. This is a direct causation where the earlier event enables the later one, establishing the Doctor's adversarial relationship with Vaughn.
