Why This Matters Across Episodes
The longer arc this connection carries
The desolate, alien environment introduced in Episode 16 ('a bleak, desolate planet characterized by crags, pools, and a thin, static atmosphere') is the same setting where the TARDIS is later dragged away in Episode 17. The planet's hostility foreshadows the threats the Doctor and Ian face after losing the TARDIS.
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.
