Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Catherine's observation at Helen's wake that Sean Balmforth's van was seen near recent murders (Episode 2) directly leads to his identification as a prime suspect in Episode 4, where Andy reveals forensic links between Sean's van and multiple murder victims."

Why This Matters Across Episodes
The longer arc this connection carries
This is a clear causal chain: Catherine's PNC check on Sean's van (Episode 2) provides the forensic link (van ownership) that ties Sean to the murder victims (Episode 4). The van becomes both a symbolic and material link between Sean's past behavior and his escalating crimes.
