Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Sisterhood's recognition that a Time Lord is nearby (Solon's castle) and their assessment of him as a threat directly informs Solon's subsequent actions. Solon, unaware of the Sisterhood’s presence but knowing Time Lords command vast knowledge, fastens on the Doctor’s head as the perfect vessel for Morbius’s brain—a cursed continuity where spiritual and surgical hubris mutually reinforce."
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.
