Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Bennett's reassertion of control and punishment of Duggan (Part 3) sets up the Cyberman infiltration, as Duggan's resentment and isolation leave him vulnerable to manipulation (Part 4)."

Why This Matters Across Episodes
The longer arc this connection carries
Bennett's punitive actions toward Duggan (Part 3) likely contribute to Duggan's later vulnerability to Cyberman control (Part 4). The mistrust sown in Part 3 enables the infiltration to go unnoticed until it's too late.
