For over a decade, Chicago Fire has taken us on an emotional roller coaster, introducing us to a family of heroes at Firehouse 51. We’ve celebrated their triumphs, mourned their losses, and rooted for them through every blaze. But with a show running this long, the doors of Firehouse 51 have seen their share of goodbyes.

While the core remains strong, many beloved characters have walked away, moved on, or tragically left us too soon. Each departure has reshaped the dynamic of the house and left a lasting impression on our hearts. Do you remember them all?

The Departed Heroes of Firehouse 51

From the very first season, we’ve had to bid farewell to some incredible characters who were once integral to the fabric of 51:

• Leslie Shay: Perhaps one of the most heartbreaking departures, Paramedic Shay was a beloved friend and partner whose tragic death in a line-of-duty incident in Season 3 left a profound void, especially for Kelly Severide.
• Peter Mills: A promising young firefighter who joined in Season 1, Mills faced personal struggles and ultimately decided to leave Chicago to be closer to his family, pursuing a career in firefighting in North Carolina.
• Gabriela Dawson: After years of a passionate and tumultuous relationship with Matt Casey, Dawson’s departure to lead a relief effort in Puerto Rico marked a significant turning point for the show and a heartbreaking end for “Dawsey” fans.
• Brian “Otis” Zvonecek: Another devastating loss for Firehouse 51 and fans alike. Otis died a hero in the line of duty during a boiler room fire in the Season 8 premiere, leaving a void that continues to be felt throughout the house. His memorial remains a powerful symbol of sacrifice.
• Jimmy Borrelli: After a terrible accident on a call left him severely injured and unable to return to duty, Borrelli’s promising career at Firehouse 51 was tragically cut short, a reminder of the job’s inherent dangers.
• Emily Foster: Joining as Brett’s paramedic partner after Dawson’s exit, Foster was a strong and capable addition to Ambulance 61. She eventually decided to leave Firehouse 51 to return to medical school and pursue her dream of becoming a doctor.
• Matt Casey: Though he makes occasional returns, Captain Casey’s move to Oregon to care for the Darden boys was a monumental shift for the series. His absence left a massive hole in Firehouse 51, particularly for his crew and his relationship with Sylvie Brett.
• Gianna Mackey: A childhood friend of Joe Cruz, Mackey briefly joined as a paramedic on Ambulance 61. She was a brave and compassionate addition but ultimately transferred to another firehouse to advance her career.

Every character who has passed through the doors of Firehouse 51 has left their mark, contributing to the rich tapestry of relationships and experiences that make Chicago Fire so compelling. Their stories, whether ending in triumph, tragedy, or a new beginning, remind us of the transient nature of life and the enduring bonds forged in the face of danger.
