Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Reegan's revelation of the astronauts' lethal capabilities and UNIT operatives' deaths in Episode 16 (scenes with Lennox and Liz) directly sets up Liz's horror and confrontation with Reegan in Episode 17 when she discovers the aliens' true form."

Why This Matters Across Episodes
The longer arc this connection carries
Reegan's matter-of-fact admission of murders ('One touch from him and down they go') and Liz's moral outrage ('You are just as guilty...') foreshadow the escalation in Episode 17, where Liz's discovery of the alien beneath the 'astronaut' suit ('ugly looking fellow') triggers their confrontation. The earlier event enables Liz's later actions.
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.
