Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Ben’s preparation of the solvent weapon (using acetone to exploit Cybermen’s plastic weaknesses) parallels the Cybermen’s later infiltration of the Gravitron Control room—both events are tactical responses to exploiting known weaknesses, but inverted in allegiance (human vs. Cyberman)."

Why This Matters Across Episodes
The longer arc this connection carries
This connection highlights evolving tactical warfare: the humans learn to exploit a physical vulnerability (plastic dissolves in acetone), while the Cybermen turn their kinetic advantage into intellectual infiltration (mind control of Evans) and system sabotage (Gravitron controls). Both are escalations based on prior identification of leverage points.
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.
