Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Marshal's order to destroy the TARDIS (and its occupants) in Episode 21 creates immediate hostility toward the Doctor and Romana, setting the stage for their capture. This act directly enables the Shadow's later control over Astra, as it ensures the Doctor's resources (TARDIS) are unavailable for intervention."

Why This Matters Across Episodes
The longer arc this connection carries
The Marshal's destructive act against the Doctor's ship instigates a chain of events where the Shadow exploits the Doctor's absence (being held captive) to manipulate Astra and advance his agenda. Without this initial aggressions, the Shadow's subsequent manipulations would lack the necessary opening.
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.
