Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's investigation of the Chumbley (starting quiet, ending with its retreat) directly leads to the Chumbley's later explosive attack on the TARDIS in Episode 2."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's initial analysis of the Chumbley's blind, tactile nature and its retreat establishes its hostile intent. This directly causes the escalation in Episode 2 where the Chumbley demonstrates hostility by attacking the TARDIS with explosives, disrupting Steven and the Doctor's rescue mission for Vicki.
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.
