Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Nyssa’s initiative in seeking the Doctor’s counsel (Castrovalva Part 4) directly informs her autonomous decision-making in Four to Doomsday Part 1, where she actively separates from Adric to take external readings—demonstrating a progression from joint action to independent technical contribution."

Why This Matters Across Episodes
The longer arc this connection carries
The earlier event establishes Nyssa’s habit of proactively engaging with the Doctor when sensing instability; this evolves into her taking independent technical initiative in the alien ship, suggesting a maturation of her problem-solving agency.
