Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor, Ben, and Polly's arrival at Snowcap Base in Episode 5 is a direct consequence of the TARDIS dematerializing from the 17th-century cave (end of Episode 4), where the Doctor had revealed their destination was 'the coldest place in the world.'"

Why This Matters Across Episodes
The longer arc this connection carries
This connection completes a clear cause-effect arc: the TARDIS’s automatic journey from Episode 4 ends in Episode 5 at Snowcap Base, Antarctica. It demonstrates the TARDIS’s role as a narrative bridge between episodes, carrying the companions from one peril to another.
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.
