Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's insistence on running the TARDIS console (despite Liz's warnings) in Episode 19 leads to the high-risk energy siphoning that causes the reactor crisis and Slocum's retrogressive transformation in Episode 20."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's reckless scientific ambition (Episode 19) directly causes the catastrophic consequences (Episode 20) through the TARDIS power trial, which destabilizes the nuclear reactor and triggers the viral retrogressive effects seen in Slocum.
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.
