Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's mission to reassemble the Key of Time (set up in Episode 9) leads directly to the Shadow's failure to secure it by Episode 26, prompting the Black Guardian's wrath in the final confrontation."

Why This Matters Across Episodes
The longer arc this connection carries
Episode 9 establishes the Key's importance and the Doctor's role in assembling it. Episode 26 shows the consequences of that mission—both its successes (defeating the Marshal) and failures (the Key's corruption)—culminating in the Black Guardian's tirade and the Doctor's ultimate resistance.
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.
