Why This Matters Across Episodes
The longer arc this connection carries
Barbara's initial entrapment (Episode 27) leads to Ian's desperate discovery of the tunnel (Episode 30), which becomes the means for the TARDIS crew's eventual escape. This connection establishes a cause-and-effect relationship between Barbara's entanglement and the crew's survival strategy.

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.
