Why These Connect
The narrative assertion
"Adric and the Doctor's discovery of a second Tardis console room (beat_49d2d71701f76033) directly enables their realization that another Tardis is materializing around the police box (beat_cba8903f10b19ab4), as the anomaly's nature becomes clearer through their investigation."
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.
