Why This Matters Across Episodes
The longer arc this connection carries
This connection establishes Vaughn's trajectory from corporate leader to willing participant in alien invasion. His admission that he plans to betray his allies ('I shall still be in control' and 'use their force... then discard them') foreshadows the Cyber Planner's revelation that he too will be discarded once his purpose is served.

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.
