I’m enjoying Line of Duty ....if I can keep up with the plot... But that DI is a nasty bit of work . And is the replacement policeman in uniform the baddy from a previous series?
Which DI are you meaning, Baz? Kelly Macdonald's character?
The replacement plod is Ryan Pilkington, who we've seen grow up since his first appearance in Series 1. He once tried to remove Steve Arnott's fingers with bolt cutters, which is why he was desperate to avoid being seen by Steve in S6E2...
