Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor deciding to leave the mysterious spaceship due to concern about someone returning or the ship's status, prompting Tegan and Nyssa to follow him back to the TARDIS (beat_42d06bd8fce4dbb0), directly causes their physical materialization on the spaceship bridge, setting up the scene where they explore the bridge and discover the transmat terminal (represented contextually by scene_36178bb5ded3e8b2 and its beats)."
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.
