Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's attempt to restore K9 using a memory wafer in Episode 19 directly enables K9's later sensor data in Episode 20, where K9 provides hard evidence of the collapsing micro-universe to the Doctor and Rorvik."

Why This Matters Across Episodes
The longer arc this connection carries
This cross-episode connection carries the narrative thread of K9's role as the Doctor's reliable, logic-driven companion who provides critical system warnings. The Doctor's investment in K9's survival in Episode 19 creates the condition for K9's effective intervention in Episode 20, where his data exposes the true crisis. This underscores K9's continuity as a character who, despite physical fragility, remains the Doctor's most trusted technical voice.

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.
