Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Daleks' testing of upgraded weapons (bullets instead of energy) in Episode 12 directly escalates the threat they pose during the tunnel confrontation in Episode 13, where they pursue the Doctor and his allies using these same weapons."

Why This Matters Across Episodes
The longer arc this connection carries
The Daleks' tactical upgrade demonstrated in their TARDIS model destruction (Episode 12) is immediately relevant in Episode 13 when they engage the Doctor in the tunnels using these upgraded weapons. This escalation demonstrates the Daleks' adaptive threat and drives the urgency of the Doctor's escape and plans.

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.
