What This Means For Mayor Of Kingstown Season 4

Season 3 Turned Into A Bloodbath For The Cast

Mayor of Kingstownis not shy about killing off characters, as was demonstrated whenKyle Chandler’s Mitch McLusky died in the very first episode. Season 2 saw another significant McLusky family death as Mike’s mother Mariam (Dianne Weist) was incidentally shot by her own son, Mike’s brother Kyle (Taylor Handley). Villain Milo (Aiden Gillen) also seemed to exit the show in a boat explosion, but season 3 revealed that he was still alive.

Clayton Cardenas was previously announced as a newMayor of Kingstowncast addition, playing Deputy Warden Torres.

But all that was just a preview of the carnage to come,asMayor of Kingstownseason 3’sending saw the deaths piling up. First warden Kareem Moore (Michael Beach) committed suicide by allowing inmates to kill him, a death that barely had time to register before Milo died for real this time, finally being shot and killed by Mike. Iris, before dying from a drug overdose, also killed Konstantin on the orders of Milo, essentially ending the Russians’ reign of terror in Kingstown.

Never one to rest on his laurels,Mayor of Kingstownproducer Sheridan then pulled one last death out of his sleeve, as the tortured Iris took pills and passed away on the bus that was supposed to take her away from Kingstown forever.

With Milo and Konstantin now out of the picture, Mike will also need a new villain to deal with.

It’s not a given, however, that “respected gangster” Moses will turn out to be an antagonist. Rounding out the new additions is Benanti, a celebrated stage actor who’s been doing more-and-more TV and movie work. With those three talented stars joining the cast, along with the returning Renner,Mayor of Kingstownseason 4 is giving viewers plenty to look forward to when it returns to Paramount+ later in 2025.
