Why These Connect
The narrative assertion
"Stapley and Bilton's infiltration and sabotage of the Master's TARDIS (Act 1) directly leads the Master to abandon the TARDIS in Act 2, trapping them aboard and forcing Stapley to attempt flying it—a desperate act that reveals the TARDIS's transformed, unstable state and isolates the companions from the Doctor."
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.
