Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Master's seizure of the Doctor’s TARDIS key in Episode 25 directly enables his theft of the TARDIS in Episode 26, setting off the chain reaction that strands the Concorde passengers and forces the Doctor to confront the Master’s new power."

Why This Matters Across Episodes
The longer arc this connection carries
This connection establishes Stapley's role as a reluctant but decisive actor in the conflict. His character's trajectory begins with protective instincts (shielding the Doctor) and escalates to active sabotage against the Master. The theft of the TARDIS key in Episode 25 directly leads to the Master's ability to vanish the TARDIS in Episode 26, thrusting Stapley into a position of leadership among the passengers, where he must take charge of repairs and negotiations.

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.
