Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Daleks' deployment of the temporal strike force and Chen's forced conscription in Episode 17 (via the homing beam and threats) directly cause his presence aboard the time machine in Episode 18, where he 'welcomes' the mission to retrieve the taranium."

Why This Matters Across Episodes
The longer arc this connection carries
This is the immediate narrative bridge between episodes: the Daleks' escalation of their pursuit into a temporal war directly enforces Chen's role as their unwilling ally in Episode 18.
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.
