Just when you thought you understood the dynamics in 9-1-1: Nashville , the trailer comes and changes everything. Before ABC released the informative teaser, we knew that Don Hart is Station 113's captain, Ryan is his son, Blythe is his wife, and that Dixie is Blue's mother. We were also aware that Blythe and Dixie don't like one another very much.

However, the 9-1-1: Nashville trailer proved that there is a lot more than meets the eye when it comes to relationships in the ABC procedural drama TV series. In fact, one huge family secret is seemingly what kick-starts the 9-1-1 spinoff's story. As a result, this shocking reveal completely reframes 9-1-1: Nashville and its overarching plot.
