Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Ian and Barbara's demand to return home (Episode 4) is a direct consequence of the Doctor's earlier deception about Susan's presence (Episode 1), which eroded their trust in his judgment."

Why This Matters Across Episodes
The longer arc this connection carries
The loss of trust in Episode 1 catalyzes the confrontation in Episode 4. The Doctor's need to 'protect' his companions by hiding truths (Susan's alien nature) indirectly leads to his companions pressuring him to break his own rules (e.g., lying about the TARDIS's capabilities).
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.
