Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The catastrophic tunnel flooding and Marat's death in Part 3 directly escalate the immediate peril in Part 4, as the Daleks now deploy anti-grav pursuit teams to hunt the Doctor and Thals in the confined cooling shaft, turning a tactical retreat into a life-or-death race."

Why This Matters Across Episodes
The longer arc this connection carries
The environment changes from a labyrinthine tunnel system (Part 3) to a vertical escape shaft (Part 4), with Rebec's movements (clinging to ropes, fear of heights) reflecting the psychological toll of escalating threats, directly caused by the flood from Part 3.
