Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The introduction and attack of the Slyther in Episode 7 creates a sense of impending danger that mirrors and foreshadows the even greater existential threat posed by the Dalek Supreme's arming of Earth's destruction device in Episode 8."

Why This Matters Across Episodes
The longer arc this connection carries
The Slyther's role as a terrifying predator within the Dalek-controlled environment (Episode 7) sets the tone for the more abstract but ultimate existential threat posed by the Daleks' plan to destroy Earth (Episode 8). Both events reinforce the inescapable and escalating danger posed by the Daleks.
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.
