Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's violent actions against Peri in 'The Twin Dilemma' (e.g., his attack on her leading to his regeneration) are a direct consequence of his instability, which was exacerbated by his near-death experience in 'The Caves of Androzani' (e.g., Spectrox poisoning, hallucinations, and desperate actions to save Peri)."

Why This Matters Across Episodes
The longer arc this connection carries
This connection carries the conflict arc of Peri's struggle with the Doctor's volatility. The Doctor's near-sacrifice to save Peri in Episode 22 creates a lingering trauma that manifests in his violent outburst in Episode 23, escalating Peri's fear and distrust of him.
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.
