Chicago Fire: What Happened At The End Of Season 9

In true Chicago Fire fashion, things were going extremely well for the heroes of Firehouse 51 at the end of Season 9... until something went horribly wrong just in time for the credits to roll. Brett and Casey were finally on the same page for better or worse, Stella had passed her lieutenant's exam and was highly recommended for a position on Engine at another firehouse, she and Severide were engaged, Boden was up for a promotion... and then Severide, Cruz, Capp, and Tony were trapped under an overturned boat, out of air, as it began to sink.
