Why These Connect
The narrative assertion
"The Doctor's suspicion of Astra after her questionable story leads him to suggest she and Merak return to Atrios via transmat. This decision inadvertently sets up the Doctor's encounter with Astra in the Zeos Interrogation Room, where she claims to be pursued by the Shadow's minions and seeks refuge in the TARDIS."
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.
