When Gallo quietly stepped away from Firehouse 51 in Season 12, there was barely a ripple. But his stunning return in Season 13 was anything but quiet. And the reasons behind his departure — and unexpected comeback — have shaken the firehouse to its core.
the departure that no one saw coming
Gallo left without fanfare, citing “personal reasons.” Viewers were told little, and even his closest friends like Violet and Cruz were kept in the dark. Rumors flew — PTSD, family issues, romantic heartbreak — but the truth remained hidden.
the shocking truth about his time away
Gallo wasn’t just regrouping — he was fighting a personal battle with addiction. After a series of secretive, high-stress rescues, he began self-medicating. When Chief Boden confronted him privately, Gallo agreed to take leave and get help. He entered a rehab facility out of state, determined to return stronger.

When Gallo walked back into 51, eyes were wide and hearts were heavy. It wasn’t just about having him back — it was about the vulnerability he brought with him. His confession to the team, especially to Violet, was raw, brave, and cathartic. Herrmann offered a rare hug. Kidd called him “family.” Even Severide, normally distant, expressed quiet pride.
gallo 2.0
Now back in uniform, Gallo is different. Calmer. Wiser. More attuned to his limits and to those around him. He’s not just fighting fires — he’s fighting to stay whole. And in doing so, he’s become a silent source of strength for others dealing with trauma.
