Why These Connect
The narrative assertion
"Corwyn calls to tell the crew of their impending danger due to the poisoning of the air supply. The Doctor hears this, and tries to warn her, but as she's getting ready to betray the imminent danger about to happen to her, she is killed, making it impossible to relay crucial information she needed to."
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.
