Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Solon’s identification of the Doctor’s Time Lord physiology and his intent to use his brain (from Part 1) leads directly to Part 2's trajectory: the Doctor risks everything to obtain the Elixir to save Sarah’s sight, knowing Solon may still threaten her through his experiments."

Why This Matters Across Episodes
The longer arc this connection carries
The threat of brain removal becomes the catalyst for the Doctor’s selfless quest in Part 2. The proximity of danger from Solon's surgery motivates the Doctor’s vow to obtain the Elixir, even if it means confronting the Sisterhood. This connection binds Solon’s earlier predation to the Doctor’s later altruism.
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.
