Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Leela's escape from the lighthouse (Horror of Fang Rock) directly leads to the discovery of the massacre at Titan Base (The Invisible Enemy), setting up the crisis in the next episode."

Why This Matters Across Episodes
The longer arc this connection carries
The urgency and danger of the Rutan threat in Episode 4 mirror the new alien threat in Episode 5, creating a thematic and narrative bridge. The unresolved tension of the Doctor's escape (with the Rutan still a threat) foreshadows the new crisis at Titan Base.
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.
