Following the events of the previous finale, one iconic Chicago Fire duo (who isn’t Severide and Kidd) encounters a big obstacle in season

14 that will make or break their relationship. The NBC procedural drama has produced various memorable and beloved dynamics over the years. However, the one in question has a long history, making their upcoming predicament all the more worrisome.

At the very least, fans don’t have to worry much about Severide and Kidd in Chicago Fire. The upcoming episodes should be a happy time for them, as they navigate this next step in their relationship (aka having a baby). That doesn’t mean everything will be smooth sailing for the couple, but they certainly won’t face the same tough problems as another duo.

As many will remember, Chicago Fire season 13 ended with Herrmann sacrificing his position at Firehouse 51 for Mouch. He decided not to take the chief’s exam, as it wasn’t what he really wanted. However, Herrmann still wanted Mouch to achieve his dream. So, he stepped down as Engine 51’s lieutenant, letting Mouch take over and leaving Herrmann as a regular firefighter.

The two friends left things on good terms in the finale, but that doesn’t mean things won’t change between them when they take on their new roles. In fact, the power dynamic switch will prove to be a problem for Herrmann and Mouch. While speaking with TVLine, Chicago Fire showrunner Andrea Newman confirmed that season 14 will test their relationship.

Newman revealed that Mouch taking over for Herrmann would bring “some of the biggest challenges to that friendship” in Chicago Fire season 14. More specifically, Herrmann will struggle with his new demotion. The showrunner teased that he will be dealing with other issues, which only exacerbate his problems with Mouch. Newman said:

The good news is that most of Chicago Fire‘s strongest relationships have survived a lot worse, and Herrmann and Mouch arguably have the most secure bond. They can withstand most storms. But only time will tell how much this latest dilemma affects Herrmann and Mouch’s friendship.
