Dermot Mulroney had an “incredibly warm” welcome from the Chicago Fire

cast, but the same can’t be said for his character, Chief Dom Pascal. “He starts

pretty strong. I don’t think he’s there to be anybody’s best friend,” Mulroney,

60, exclusively told Us Weekly of Pascal’s Firehouse 51 entrance during the season 13 premiere, which airs on Wednesday, September 25. “He’s gonna lay down the way he sees that things should go.” Mulroney’s Pascal will have big shoes to fill as the new leader, which the actor told Us won’t be easy to do. “He’s an extremely moral guy. … He’s tested on it a couple of times early in the season,” Mulroney explained, noting that Pascal, who is from Miami, will lay down some “new rules around the firehouse” that don’t sit well with everyone. He teased, “He’s not there to get along with everybody.

By the opposite token, he’s a boots on the ground firefighter.” Jenn Tran Doesn’t Let Ex Matt Rossi Join ‘The Bachelorette’ Related: ‘Chicago Fire’ Season 13 Kicks Off This Month: Everything to Know Mulroney revealed that Pascal “walks right into” all the fire incidents when he first joins the Windy City crew “without any hesitation.” That shows that “he’s as much a part of taking a fire out as everyone else that pulls up from the firehouse,” he added. Hanako Greensmith, who plays paramedic in charge Violet Mikami, exclusively told Us earlier this month that Pascal “comes in a bit like a firecracker.”

She called the new character a “bit of an anomaly” and a “bit of mystery.” Dermot Mulroney Teases Chicago Fire Debut Says Pascal Isnt There to Be Anybodys Best Friend: Peter Gordon/NBC Miranda Rae Mayo, who portrays Lieutenant Stella Kidd, agreed that Pascal is “a tough one to read and he is also very confident in his way forward.” She exclusively told Us that the new leader “comes in and has his way,” but the rest of the crew has “a certain pride” in how they’ve always worked together. Mulroney said that Greensmith’s “firecracker” descriptor is very accurate, teasing season 13 is “really physical” and leans “into the action” more than he expected. “Things are bigger, louder and [there’s] bigger explosions,” he shared.
