Why These Connect

Why This Matters Across Episodes
The longer arc this connection carries
The Sisterhood's initial detection of the TARDIS and identification of the Doctor as a Time Lord in Episode 17 sets up their hostile actions in Episode 18. Their scrying ritual is the direct cause of the Doctor's capture and attempted sacrifice.
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.
