Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's insistence on investigating temporal anomalies in Episode 13 (despite Tegan's skepticism) foreshadows his later expertise in crises like the Cybermen attack in Episode 21, where his knowledge of containment fields and antimatter is critical."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's investigative instincts and technical curiosity, first displayed in investigating a 17th-century England anomaly, are directly responsible for his capacity to stabilize the freighter’s bulkhead in Episode 21 using antimatter physics — a skill that saves the day.
About Causal Connections
