Chicago Fire
Here’s what fans can expect from “Chicago Fire” Season 5. NBC

Dawson (Monica Raymund) and Casey (Jesse Spencer) will continue on as a couple in “Chicago Fire” Season 5, but as has always been the case, it won’t be a smooth ride throughout for the two, series co-creators Michael Brandt and Derek Haas have teased.

At the end of “Chicago Fire” Season 4, Dawson and Casey saw some sort of resolution and even ended up with their new foster son, Louie. But in any case, some issues have yet to be settled between them, as well as with Susan (Lauren Stamile).

“We're going to pick up with them with the new foster son Louie, and Dawson and Casey together as a couple going forward, but the woman who played Susan who was the political consultant, she is not quite done with Casey,” Haas told The Hollywood Reporter. “She's the one who kissed Casey at the end and gave him her hotel number. She is going to be a complication at the beginning of the season.”

Brandt, meanwhile, said that although they would like to see Dawson and Casey stay together, as do the fans, they’re not going to make it easy for the couple.

“We've had so much fun with Casey and Dawson over the last four years of will-they-won't-they-when-will-they and they are a couple I think everyone wants to see be together,” says co-creator Brandt. “We want to see them be together, but as always, we want to make it as difficult as possible on them. So while they try and build their family, there will definitely be some things that come along that get in the way of that.”

Brandt told TVLine that in bringing Casey and Dawson back together in the finale of “Chicago Fire” season 4, they were finally able to offer a happy ending for one of the show’s seasons.

As the actor portraying Casey, Spencer also has something to say about his character and how his life with his fiancée and new son will be in the upcoming season.

“We’ll be adjusting to having a family. You know, now they have a child, an adopted child, so they’re going to have to figure out how to make that work. The idea that they’re both in a dangerous profession with a child and both on the same truck is just not going to fly,” Spencer told Entertainment Weekly.

“Chicago Fire” Season 5 premieres on Oct. 11 at 10 p.m. ET on NBC.
