Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Cybermen's ambush in the sewers (Ep16) and their failure to contain UNIT forces (due to erratic behavior) directly enables the Doctor's later confrontation with Vaughn (Ep17), as the resistance's continued presence in London forces Vaughn to maintain his control over the Cybermen."

Why This Matters Across Episodes
The longer arc this connection carries
The Cybermen's initial failures in the sewers demonstrate their vulnerability and UNIT's resilience, which undercuts Vaughn's confidence in their obedience. This sets up the Doctor's argument that Vaughn cannot fully control the Cybermen, as seen in Vaughn's office in Ep17.
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
