Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Baker’s imprisonment by the Silurians and his collaboration (Part 4) leads to his subsequent infection by the Silurian plague and betrayal of the Doctor (Part 5), creating a direct causal chain of events."

Why This Matters Across Episodes
The longer arc this connection carries
In Part 4, Baker is discovered imprisoned by Silurians and warns the Doctor about their intelligence-gathering for invasion. In Part 5, Baker returns infected, accusing the Doctor of colluding with Silurians ('Oh yes, I saw him all right, with his Silurian friends!'). This reflects how Baker’s earlier captivity and exposure to Silurian methods in Part 4 directly leads to his later madness and accusations in Part 5.
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.
