I just can't buy for one second that killing Shay was the best choice for repercussions through the characters. That should totally have been Casey if that's the impact they were truly going for. It would have been a huge blow for Severide. It would have not only been huge for Dawson, but then she could have stayed on as a firefighter at 51 knowing she's only there cause Casey died. And they could have promoted Herrman to Lt and he would have had a lot to deal with knowing he's in Casey's spot just because he died. Plus it also would have allowed them to bring back Rafferty (assuming the actress was available), someone that many of the fans really enjoyed, to take the other Paramedic spot with Shay. Maybe some people out there still enjoy watching shows compromised almost exclusively of straight, white male characters, but I'm not one of them. This show just went from "appointment" Tv for me to "maybe I'll get around to it over the weekend" Tv. Catastrophically poor decision, imo.
