Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The discovery of the Doctor's abandoned belongings in Episode 2 (his broken Geiger counter, hat, and notebook) sets up_susan's later emotional reaction in the Cave of Skulls, where she uses the Doctor's absence (implied by his missing notebook) to justify his capture and rally the group."

Why This Matters Across Episodes
The longer arc this connection carries
The abandoned belongings in Episode 2 foreshadow the Doctor's vulnerability and Susan's emotional reliance on his presence. In Episode 3, Susan's urgent belief that the Doctor has been taken ('Something terrible has happened to him, I know it has') echoes the consequences of his earlier capture, tying the two events together as causal to her distress.
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.
