Pruitt’s sudden departure leaves a leadership vacuum. While Jack Gibson is initially put in charge, Andy Herrera —motivated by childhood friend Ryan Tanner—decides to fight for the captaincy herself.

Ben Warren , a former surgeon from Grey's Anatomy , begins his journey as a rookie firefighter. He struggles to adjust to the frantic, less-controlled environment of field emergencies compared to an operating room.

During the fire, Captain Pruitt Herrera collapses and is rushed to Grey Sloan Memorial Hospital. It is later revealed he has cancer, forcing him to step down immediately.
