Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Jamie and Ben’s discovery of the hidden tunnel during their escape (Episode 20) directly provides the means for Ben to reveal to the Doctor in Episode 21 how the group found the secret room (via a tunnel in the mines)."

Why This Matters Across Episodes
The longer arc this connection carries
This connection bridges Episodes 20 and 21 through Jamie’s role as a passive but pivotal witness to the tunnel’s discovery. His silence in the reveal scene (Episode 21) contrasts with his active participation in the escape (Episode 20), showing his continuity as a trustworthy ally who connects disparate groups—miners and TARDIS crew—across episode boundaries.

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.
