In an interview with NBC Insider on May 21, 2025, Chicago Fire showrunner Andrea Newman talked about Kidd's pregnancy.

"I think there’s something that happened there that gave Kidd a little more faith in herself and in this couple to maybe take that leap. And be a little less trying to plan everything and more leaving some things to chance and accepting that she can handle it no matter what it is that comes."

Mayo joined the show in 2016 and has also appeared in Pretty Little Liars, True Detective, Blood & Oil and Days of Our Lives.

In an interview with CinemaBlend on October 8, 2025, Stolte discussed Mouch's upcoming arc:

"We're blessed with the gift of longevity on this show. We've been around a long time. We've been around long enough for people to age and change and evolve, and that's what has happened. When it all came down to him deciding to shed the half man, half couch identity, and to actually apply himself full force to his job, that put the character in a different place, and suddenly all of his years of experience were focused on leadership. [They] were focused on getting the job done and calling the shots and not just taking orders anymore."

Stolte’s previous work includes Law Abiding Citizen, Public Enemies, Prison Break and The Playboy Club.

In an interview with TVBrittanyF.com dated October 22, 2025, Brandon shared the following about his character,

"What’s nice is, as the season progresses, we start to discover that Sal actually has a past of being somewhat involved in the police academy. So it’s cool because I get to kind of incorporate all of the tools that I learned at On Call, and kind of bring a smidgen of that into this new project."
