What makes Chicago Fire a must-watch show is it's not just about its plotline and heroic moments, but mainly the struggles behind the people in uniforms and how much they sacrifice.

Ever since the very first season of Chicago Fire, Randy McHolland, popularly known as “Mouch”, is well known for his wit, dedication, hard work and bravery serving at Firehouse 51 for decades. He has been the heart and soul of Chicago Fire since the beginning of the show. Christian Stolte plays Randy McHolland, who is a fan favorite due to his positive outlook, good humor, and ability to handle difficult situations with composure and poise. His efforts paid off in season 14, and he received a promotion that was well-earned after a year of devotion and hard work.

Chicago Fire Season 14: Mouch gets a promotion

Season 14 came with many surprises and unexpected turns, bringing new characters and more heartfelt moments. The entire season 13, Mouch suffered from the thoughts of stagnation and questioned his position at the station. He wanted more growth and development for himself. Mouch felt like he was overlooked to take up any sort of leadership role, even after decades of loyalty and hard work. He was motivated by Herrmann himself to give his lieutenant's exam, as both desired a promotion and believed in each other’s potential. 

But it turned out that fate had already made plans for both of them. In the final episode of season 13, Herrmann voluntarily stepped down from his lieutenant position. This decision was both shocking and very unexpected, given the timing. Mouch was promoted to be the new lieutenant. Mouch accepted the position, which was a significant turning point in his career.

Chicago Fire Season 14: New leadership, new beginnings

Season 14 picks up from Mouch's transition into his new role as the lieutenant. He approaches his new role with ease and keeps his fun personality alive. He has been the team's moral compass and comic relief for years, but now he has to deal with the strain of command, which includes making difficult decisions, leading Engine 51's crew, and taking Herrmann's place.

On the other hand, there is some tension between Herrmann and Mouch as Herrmann returns to his firefighter duties. Both are seen dealing with change and getting used to the new dynamics. The episode explores the effects of these changes on the team's cohesion under Mouch's leadership.
