Why These Connect
The narrative assertion
"Nyssa's preparation of the sonic disrupter in the TARDIS (beat_7028e2eb20ce1b6c) enables her to deploy it successfully against the android in the girl's bedroom (beat_ef9a102d7cec3759). This cross-scene action directly saves the companions by neutralizing the android threat."
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.
