Many new roles for our characters and many events that happened. Here’s a full episode breakdown. After a late night of serious drinking, Severide stumbles to the nearest CTA station on his way home, but gunshots and screams interrupt the ride. He locates the shooter – and a wounded train conductor – in the front car and finds himself staring down the barrel of a gun. When the kid refuses to back down, Severide takes him by force, knocking the kid out and tossing his weapon. He rushes the conductor to a nearby station and improvises a temporary dressing on her wound, then sets off a fire alarm to alert police. Before the alarm sounds, the shooter tracks him down, now backed by his angry partner. With a gun to his head once again, Severide braces for the worst – saved only by the timely arrival of Burgess and Roman from Chicago P.D.

Back at 51, Severide doesn’t tell anyone about his crazy night. That is until Boden calls him into his office. The chief, is none too pleased with all of his recent post-shift antics as he threatens him to shape up or risk losing his position. Being a firefighter isn’t just about doing the job it’s more than that. Casey seeks out his friend, too and reminds him not only what he did for him but a very important fact. Which is that the firehouse needs him. But a glimmer of hope comes as the injured conductor he helped save in the beginning of the episode comes to the firehouse as she thanks him for saving her. When Severide credits Shay with teaching him the right skills, the conductor takes his hand and confidently states that Shay is here. She can feel her presence.

Another presence receives due recognition at the station when an inspector gives his full attention to the Molly’s II food truck… and finds it faulty in a litany of new regulations, racking up a cost of about 30 grand. Boden delivers more bad news to Herrmann – his lieutenant position at another firehouse fell through. It’s not until later that Herrmann discovers a connection between the tough inspector and his lost bid for lieutenant – Chief Hale, the inspector’s boss, has a vendetta against him. When the chief refuses to meet at the office, Herrmann blindsides him at his house, where he learns exactly why Hale holds a grudge and shows him his stockpile of energy drinks, a failed product from Herrmann’s past. Oops? Now how is Molly’s suppose to open?

Meanwhile, it’s Dawson’s first day as candidate, and she somehow manages to steer clear of the usual string of pranks, much to the chagrin of Herrmann, Cruz, Mouch and Otis. More importantly, she struggles to find the right tool during an intense rescue and the guilt forces an awkward apology to Casey. She redeems herself during her first real fire where she locates a water source after vandalism renders the closest hydrants inoperable, and her quick thinking results in the rescue of 15 trapped kids, all involved in a sweatshop situation. The station celebrates afterwards… and she finally falls victim to a confetti prank in the fire truck.

In a less festive mood is Brett. Not only does she dwell on the one casualty from the fire, but she can’t seem to shake the arrival of her ex-fiance Harrison. Despite the fact that he called off the wedding, not Brett, he now assures her he wants her back. The intensity of her EMT work in Chicago makes her wonder if returning to Indiana is the right thing. When Mills, her new partner, issues a warning about maintaining focus, Brett knocks on Harrison’s hotel door in tears. Damn, so does this mean she’s going back to him? Well there’s more to be had for her and the rest of the firehouse. Here’s a sneak peak of next week’s episode.
