Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's revelation that only two functional TARDIS machines exist (in cand_evt_scene_cc6f1051f6ad7dbf_01) forces his desperate decision to summon the Time Lords, which directly leads to his trial before them in Part 10."

Why This Matters Across Episodes
The longer arc this connection carries
This connection carries the entire arc of the Doctor's rebellion against Time Lord laws. His earlier admission of needing to 'call them in' to end the War Games becomes the very catalyst for his trial, stitching the episode's climax into the series resolution.
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.
