Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Brigadier’s assignment of Chin Lee’s surveillance (Episode 5) leads directly to Yates’ report of her disappearance (Episode 6), which the Doctor links to the Keller machine’s installation and Emil Keller’s Chinese assistant."

Why This Matters Across Episodes
The longer arc this connection carries
This connection is causal in UNIT’s operational continuity: a side mission assigned in Episode 5 (tracking Chin Lee) creates the setup for the unresolved mystery in Episode 6, which the Doctor directly ties to the Keller machine’s origins.
About Causal Connections
