Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor entrusts Jo with time detection immediately before (cand_evt_scene_280dec20bda916d8_01) the TARDIS is assaulted and they are forced into the time chase. This establishes Jo’s technical competency and prepares her to later follow the Doctor’s disembodied directions while the TARDIS collapses (cand_evt_scene_58e6a25f59a6d03_1) in Part 5."

Why This Matters Across Episodes
The longer arc this connection carries
Jo’s entrustment in Part 4 as the Doctor’s technical assistant directly enables her ability to act decisively under pressure in Part 5, where she must operate an emergency protocol under duress using the TARDIS systems. This continuity cements Jo’s evolution from a methodical assistant to a critical operator in crisis situations.
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.
