Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The War Lord's execution of the War Chief (directly causing chaos and exposing the War Chief's treachery) sets the stage for the Doctor's desperate flight from the Time Lords in Part 10, as the remnants of the War Games regime lash out."

Why This Matters Across Episodes
The longer arc this connection carries
The fallout of the War Lord's power struggle (exemplified by the War Chief's execution) creates the immediate threat that forces the Doctor to flee the War Games, inadvertently triggering the Time Lords' pursuit. This chain of cause-and-effect links the temporal conflict (War Chief's downfall) to the Doctor's existential crisis (Time Lord pursuit).
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.
