Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Nyssa and Tegan's deduction about the Doctor's fractured regeneration and the Zero effect (Episode 3) directly leads to their later examination of Castrovalva's fabricated history (Episode 4). The companions' analytical skills, honed during the blood trail scene, are applied to exposing the town's recursive nature."

Why This Matters Across Episodes
The longer arc this connection carries
Nyssa's ability to dissect complex systems (e.g., the Doctor's trauma) is extended to Castrovalva's history. This causal link demonstrates her evolving competence and the Doctor's trust in her analytical mind as he guides the investigation.
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.
