Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor calls the Megara as his final witness (beat_be48a1288820ee8d), which directly prompts them to reveal their destination and mission: to try Cessair of Diplos for murder and misuse of the Great Seal (beat_0ec86cdf608088d8). This is the crucial turning point where the Doctor gathers the legal and narrative evidence needed to link Vivien to Cessair."
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.
