Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor entrusting the Great Key to Leela in Episode 25 directly causes the Sontarans’ biometric tracking failure in Episode 26, because she retains the artifact’s energy signature, making human life forms untraceable."

Why This Matters Across Episodes
The longer arc this connection carries
This is a direct causal chain: the Doctor’s faith in Leela’s reliability (entrusting her with the Great Key) results in the TARDIS containing a form of resistance the Sontarans cannot detect—biological barrage/tracking failure. It elevates Leela from combatant to pivotal asset in the war strategy.
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.
