Leslie Shay Died During The Chicago Fire Season 3 Premiere
At the end of Chicago Fire season 2, Firehouse 51 responded to a building fire. All the firefighters and paramedics, except for Chief Boden,
rushed inside, but an explosion rattled the structure just moments later. The episode concluded without the audience knowing the
characters’ fates. They had to wait until the season 3 premiere to learn that Leslie Shay had been killed.

Severide and his wife, Stella Kidd, learned that she was pregnant during the Chicago Fire season 13 finale. The two had been wanting to start a family since earlier in the season, and at first, they thought Kidd wouldn’t be able to get pregnant. As a result, Severide and Kidd (who fans affectionately call “Stellaride”) tried the adoption route.
Adoption didn’t really work either. They almost got a baby, but the biological mother quickly changed her mind after giving birth, wanting to keep her child. Consequently, things were not looking good for Severide and Kidd. At the end of Chicago Fire season 13, though, Kidd discovered that she was pregnant, and she and Severide rejoiced in the news.

Severide and Shay’s relationship was arguably the best one on the show, and they even almost had a baby together (platonically). They were so close, and it was heartbreaking to see Severide grieve her. He just loved Shay so much. So, naming his child after her would only be fitting.
Severide and Kidd naming their baby after Shay would be the perfect way to honor her legacy and keep her relevant even 11 years after her death. It would also be a nice treat for the fans who miss her dearly. Plus, it also helps that Shay had a gender-neutral name that could work for a boy or a girl.
