The Rookie is a good show. It sounds like you stepped into the middle of a storyline that has developed over several episodes. If you have On Demand on your TV I recommend you go back 3 or 4 episodes and pick it up from there.
For what it’s worth I think you are right.
I realized that obviously I ended up somehow in the middle of some kind of story line that had Nolan in trouble with Internal Affairs and he was innocent.
Appreciate you suggestion of On Demand but not going to bother.
I will watch the show again but I want to watch fresh story lines.
