While the Kingstown mayor was struggling to keep his baby brother out of prison, new distractions and enemies were slowly rising against him. The introduction of two new key characters also raises the stakes for Jeremy Renner's character.If the explosive Season 4 premiere wasn’t proof enough, Jeremy Renner has confirmed that the new season will push the stakes even higher for the McLusky family. In an interview with The Hollywood Reporter, the actor teased:“It’s a very complicated show. Even four episodes in, there is a lot that goes on, man. It’s pretty intense...Buckle up! Because it ramps up. There are a lot of shockers in this one.”Falco added:''And probably what you think is going to happen is not going happen. As I was reading the scripts, I was like, ‘Are you kidding me!'”Exploring Mike McLusky's 'biggest obstacle' in Mayor of Kingstown Season 4 View this post on Instagram Instagram PostThe Mayor of Kingstown Season 4 premiere began in the aftermath of the Season 3 finale, where Kyle McLusky shot Robert Sawyer. While Mike tried to keep his baby brother away from prison, it was decided that Kyle would be sent to the Anchor Bay prison after he entered into a plea deal to save Robert. After Mike failed in this task, his next step of action in the latest season will be to protect his brother from the outside.Jeremy Renner further discussed Mike's mission in Mayor of Kingstown Season 4:“Some of the biggest obstacles are in Mike’s way. It’s like one note in a lot of ways, the drive of: All I have to do is protect my brother. And there’s a lot of things on the outside of that, which I think draws in the narrative of a lot of the show’s characters, around this main narrative.”The biggest obstacle standing in Mike's way could be Falco's newest character, Warden Nina Hobbs. While Mike tried to cut a deal with Nina, she subtly warned him that she would not do any favors for the McLusky brothers. This could be a turning point for Kyle's prison arc because his brother will not have the same influence from the outside, thanks to Falco's new warden.The Mayor of Kingstown Season 4 premiere even foreshadowed Kyle's fate in prison, after a fellow prisoner brutally beat him with a lock hidden inside his sock. With Mike's hands tied, it would be interesting to see how Kyle will survive in prison.Elsewhere, Moses' brutal assassination of the Russian mobsters could materialize into a dangerous partnership with Bunny, the leader of the Crips in Kingstown. This alliance could turn deadly for Mike McLusky, who is already preoccupied with keeping Colombian cartels at bay.Mayor of Kingstown Season 4 will release weekly episodes every Sunday on Paramount+. Episode 2 is titled "Promises to Keep" and will arrive on November 2.For the latest scoops on your favorite TV shows and movies, follow SoapCentral.
