Dawson stresses about her upcoming firefighter's exam, and with good reason - if she passes, Boden cannot keep her at 51. She learns about an opening at a firehouse in a neighborhood outside town, headed by the unflappable Tommy Welch. When Dawson and Shay drive over for an introduction, they receive a cold reception and Welch makes it clear - no one on the squad wants a female firefighter.
Another unwanted female makes a surprise appearance at 51 looking for Shay - her ex-girlfriend Devon, the one that stole from her, Severide and Otis a few months back. Livid, Shay demands Devon return everything she stole, but softens just enough to agree to a meeting. Her ex hands over Otis' "Battlestar Galactica" helmet and a small sum of money, all accompanied by a story involving her father's spat in jail. Shay relays the story and the money to Severide - and he rejects both, accusing Shay of letting Devon walk all over her.
