Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s assertion in Part 4 that Vaughn’s crates are linked to an extraterrestrial threat (via photographic evidence of UFOs near Vaughn’s factories) directly causes his later revelation that Cybermen are collaborating with Vaughn, uncovering the existential scale of the invasion."

Why This Matters Across Episodes
The longer arc this connection carries
The earlier establishment of Vaughn’s industrial operations as a conduit for alien activity (UFO sightings) logically escalates into the Cybermen revelation. This causal chain transforms a local corporate threat into a global invasion, with Turner’s observations of UFO files serving as the critical bridge.
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.
