Why These Connect
The narrative assertion
"Doctor 2nd's dismantling of the handset (beat_b318c166fe6b49d9) leads directly to progress on communication in the TARDIS (beat_5f7866d37822637c), where he and Benton discuss their progress and he converses with another version of himself."
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.
