Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Chela's theft of the cell key in Episode 7 (cand_evt_scene_9d574afe59071d5c_1) enables her to free the Doctor and Nyssa, who then actively engage in disrupting Lon's ritual in Episode 8 by seizing the Great Crystal (cand_evt_scene_d3e624fb3c7c24b3_2)."

Why This Matters Across Episodes
The longer arc this connection carries
Chela's subversion of Lon's authority in Episode 7 sets the stage for the Doctor's resistance in Episode 8. Her act of defiance—taking the key—directly empowers the Doctor's later seizure of the Crystal, linking their shared mission to dismantle Lon's corruption across episodes.
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.
