Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s use of the power surge to destroy Cybermats in Episode 39 causes the Cybermen to escalate their tactics to direct confrontation (meteorite assaults, air-poisoning plots) in Episode 40."

Why This Matters Across Episodes
The longer arc this connection carries
This connection shows Jamie’s gradual acceptance of the Doctor’s unorthodox problem-solving. The Doctor’s improvisation with the power surge (39) sets up his later justification of risking lives for the greater good ('It's an act of war... I'm prepared to take that risk'), which Jamie grapples with but ultimately accepts.
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.
