Why These Connect
The narrative assertion
"The Doctor's decision to sign the Vardan document (granting him 'complete control over the Time Lords') directly precipitates his subsequent claim to the Presidency of the Time Lords upon arrival on Gallifrey. His audacious move in the Chancellory is the practical execution of the plan negotiated with the Vardans."
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.
