Warning: This article contains spoilers for Chicago Fire Season 13

All of this comes fairly soon after Mulroney’s character joined the show following the departure of former Chief, Wallace Boden (Eamonn Walker), in Season 12. MovieWeb’s George Edelman caught up with Mulroney to discuss how it felt to join such a popular and well-established show and effectively take over from one of the show’s most loved characters. During the conversation, Mulroney shared a teasing insight into the upcoming return of Walker as Boden, and how their worlds will collide.

“I had no concept of how beloved Boden was – Eamonn Walker’s character – as the chief for all those years. So that’s built in, knit into the part of Pascal, who that other guy was. And it’s been amazing to learn that you see, coming up, Boden comes back at least for one episode and it’s really a special visit that everyone there was thrilled that he returned. Meaning literally cast, crew, everyone. But the episode is really interesting too, so stay tuned for that. And I got to work really head-to-head with him, in some intense scenes. So, they didn’t pull any punches.”

“They’ve had great fun showing me as kind of a hardass I guess, for lack of a better term, but he keeps kind of coming through for people a little bit, maybe behind the scenes somewhat. So, the viewers this season get the feeling that he’s a pretty good guy behind all that. But then, sh-t goes down for him and then who’s there for him… you’ll see. It’s amazing how the tables turn and then, before you know it, they have to intervene on his behalf for a number of reasons, but emotionally too, so it’s amazing in these upcoming episodes to see how that plays out where they’ve really got his back as he’s kind of failing at the grieving process.”

Mulroney is now hopeful that Chief Pascal will be able to have a long run on the show, and he is only just starting to get to grips with the character. The actor added
