Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Tegana's sabotage of the water supply (cand_evt_scene_0f3ad941129b3374_01) escalates his reputation as a treacherous figure in Episode 16 (cand_evt_scene_013e2b68a6794277_03), where Polo confines the Doctor and his key, partly due to the lingering distrust from the sabotage."

Why This Matters Across Episodes
The longer arc this connection carries
The sabotage directly undermines Polo's trust in the group (and vice versa), creating a rift that allows Tegana's deceit to flourish. Polo's later actions (confiscating the TARDIS key) are a direct reaction to the earlier crisis.
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.
