Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's summation of returnees' freedom (only two machines left) in Part 9 prompts the Time Lords' judgment and dematerialization of the War Lord in Part 10."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's dire warning about the dwindling ability to return people to their own times (Part 9) frames the Time Lords' intervention in Part 10 as both necessary and final. The War Lord's dematerialization is a direct consequence of the chaos documented in Part 9, tying the two episodes together through the escalation of the temporal conflict.
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.
