Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's successful demonstration of calming and controlling Aggedor in Episode 17 (Part 3) directly enables his ability to weaponize and summon Aggedor again in Episode 20 (Part 6). The skills and understanding of Aggedor's nature developed in the first instance are critical to the later use."

Why This Matters Across Episodes
The longer arc this connection carries
This connection underscores Aggedor's role as a recurring tool for the Doctor, with the earlier success in Part 3 providing the necessary precedent and respect with the creature that permits its later deployment as a tactical weapon against the Ice Warriors. Without the earlier episode's demonstration of Aggedor's responsiveness to the Doctor, the later events would lack narrative credibility.
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.
