Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's order for Yates to return to Global Chemicals (E25) leads to the Brigadier later delivering a contaminated slag sample (E26), which is the direct cause of the Doctor's breakthrough in understanding the maggot transformation."

Why This Matters Across Episodes
The longer arc this connection carries
This connection drives the critical scientific and narrative escalation: Yates' infiltration of Global Chemicals is explicitly facilitated by the Doctor's command in E25, and the Brigadier's physical retrieval of contaminated slag in E26 enables the Doctor's research into the alien pathogen.
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.
