Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's negotiation terms in Episode 19 (handing over hostages) successfully secure Steven and Sara's release, allowing them to regroup with the Doctor in the TARDIS. This reunion is the starting point of Episode 20 where the TARDIS's directional unit failure strands them on Kembel."

Why This Matters Across Episodes
The longer arc this connection carries
This connection carries the narrative thread of survival and companionship. The immediate aftermath of the hostage situation (Episode 19) directly transitions into the TARDIS malfunction (Episode 20), establishing the threat of being stranded and setting up the Doctor's pessimism versus Sara's growing frustration.
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.
