Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Noah's violent struggle against the alien parasite (Episode 7) leads to his full assimilation by the Wirrn, which is confronted by the Doctor in the control room in Episode 8. Noah's physical transformation and vocal change in Episode 7 directly cause his role as the Wirrn's vessel in Episode 8."

Why This Matters Across Episodes
The longer arc this connection carries
This connection carries the evolutionary escalation of Noah's possession from partial assimilation (Episode 7) to full control by the Wirrn (Episode 8), driving the conflict arc of humanity's failed quarantine and assimilation by an advanced alien species.
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.
