Fire Country Season 4 kicks off with the show's biggest twist yet — a major character death. The trailer for the hotly anticipated fourth season revealed that fan favorite Chief Vince Leone (

Billy Burke) died in the Bella Vista fire, forever changing the lives of his fellow firefighters. Season 4 is heavy with mourning as everyone says goodbye to Vince, but they still have a job to do, and someone has to pull Station 42 out of their grief. 
Shawn Hatosy joins the show as Battalion Chief Brett Richards, a no-nonsense Cal Fire titan. Co-creator Max Thieriot spoke to Collider's Christina Radish about Chief Richards' effect on the station in the wake of Vince's death. "He’s definitely [going] to shake things up," Thieriot said. "It’s not that we have one person who needs direction at this moment, and you’re bringing in someone to mentor them," he added, revealing the challenging task that is ahead for Richards. A whole station needs fixing. He explained, saying:

"The station is broken, and it’s broken because it lacks leadership and that key voice of reason and that’s someone that everybody looks to. Bringing in Shawn is also complicated because he comes in at a really difficult and complicated time for all of these people. They’re really just trying to pick up the pieces. 

He’s a character that is incredibly smart and methodical and has been doing this job for a long time. But our characters and the station are still reeling, and they don’t know how to put one foot in front of the other yet."

However, Station 42's firefighters are not the easiest to deal with, and the circumstances are not helping. "Anybody coming in, at that point in time, is going to feel like they’re trying to erase the past and take the place of somebody. 

That’s going to create friction that doesn’t necessarily need to be there and isn’t necessarily warranted. As we all know, when people are going through really difficult times, they react maybe not in the best way, just because of where they’re at, personally and emotionally, and we get to really see that. These people just want things to be back to the way they were, but that isn’t the reality anymore," Thieriot explained.

The show's official description of Brett Richards describes the chief as, "a roving Cal Fire station fixer, [who] prides himself on his contradictions, especially because they keep others guessing and on their toes. A no-BS, blunt-talking, ATV-riding cowboy type with a renegade streak, Richards is also a hard stickler for the rules, as he hammers a grieving Bode and the 42 crew with a battle cry of 'No more dead firefighters!' and a polarizing leadership style that gets under everyone’s skin. But there’s a method to Richard’s madness. Holding two master's degrees, Richards isn’t just an expert in fire behavior. Human behavior is his true expertise. As Bode, Sharon, and the rest of 42 still reel from Vince's death, Richards, no stranger to loss himself, is determined to break our fragile heroes all the way down in order to put them back together."

Shawn Hatosy Boosts 'Fire Country' Season 4

Chief Richards will have a profound effect on the characters this season. "Shawn is there for a while in the beginning, and then he'll be coming back.

 We also will get to experience real growth, not in his character as much as our characters and the way that we view him, which will be really fun and exciting," Thieriot said. "We'll get to see sort of 

a different version of what 42 looks like with that person and how our characters adjust to a different way of things," he added. An actor like Hatosy elevates the characters he plays, and Thieriot was excited about his contribution to 
Fire Country. He expressed his excitement by praising Hatosy's past work, saying:

"And with Hatosy, I love the dude. He’s an incredible actor. I’ve been a huge fan of his, since forever, even back to 

The Faculty. He’s been doing incredible work for so many years. It’s really cool to see him finally recognized. He’s a guy who shows up and puts in the work and really delivers, every time,
 whatever it is that he has. It’s not that he’s gone under the radar but maybe hasn’t been given as much recognition as he probably deserves over the years, for the great work that he’s done, with 
Animal KingdomSouthland, and Alpha Dog. You watch a couple things that that dude’s in and you’re like, 'Oh, man, this guy can act.' So, I couldn’t be more thrilled to have him be a part of the show.'"
