Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Jamie's recognition of the pyramid-shaped device as the Great Intelligence's control source (from Part 2) directly informs the Doctor's later deduction that Travers was taken 'for something,' implying the Intelligence's need to exploit his research."

Why This Matters Across Episodes
The longer arc this connection carries
This connection bridges the narrative from Part 2 to Part 4 by establishing the Great Intelligence's overarching goal (using the pyramid/sphere to control the Yetis). Jamie's insight about the pyramid in Part 2 is later validated when the Doctor deduces Travers was abducted for 'something,' tying the pyramid to Travers' expertise.
