Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's outmaneuvering of Chen and the Daleks in Episode 19 leads directly to Chen's overconfidence and boastfulness in Episode 20, which the Daleks exploit to dissolve the Galactic Council."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's deception (handing over the fake Taranium Core) forces Chen into a position where he must prove himself to the Daleks. This pressure manifests as arrogance and a need to assert his importance in Episode 20, which the Daleks then use to manipulate the Galactic Council.
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.
