Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Thackeray's delivery of the telex warning about Winlett's infection (Episode 21) creates the foundation for the Doctor's accusation of a bureau leak in Episode 23, as the telex itself could have been the source of outside knowledge."

Why This Matters Across Episodes
The longer arc this connection carries
The telex reporting the pod's danger is the only documented channel through which external actors could have learned about the pod's discovery. This makes Thackeray's role as messenger a potential vector for leakage, which the Doctor explicitly names in Episode 23.
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.
