Continuity mistake: The series doesn't seem sure what Sunny's rank is. He is described at various times both on screen and in the credits as both Detective Inspector and Detective Sergeant.
Episode #2.6 - S2-E6
Continuity mistake: In the train platform scene where Cath stops Jason from jumping in front of the train, she asks him if he wants a cup of tea. He replies yes. It then cuts to a shot from the other side of the track showing Cath briskly walking away from Jason. However, in the next cut, we see Cath standing in front of Jason suggesting a diary date.
