There are big changes coming up for Nathan's character in the new season
There's been plenty of speculation that filming is kicking off on the new season any day now.
Season three ended on a cliffhanger and The Rookie's showrunner, Alexi Hawley, revealed Nathan's character, John Nolan, has some big changes coming up.
John will no longer be a rookie or in training and this changes a lot for him. Alexi told TVLine:
"It's exciting going into season four with things that we haven't done before, with dynamics we haven't put together. Also, what's inherent in not being a rookie or a student or a trainee, is that he'll have a bit more strength because he's going to be the one making the calls."
