According to the site I stream episodes on, there's only one episode left. And it's called Requiem. Which is definitely a series finale type name.
I just don't see how they can wrap everything up in one episode. We still have the Brotherhood, Maggie and Bunker, Proctor's drug issues, Hood and Carrie and their kids, and now that the Sheriff knows about Hood's past how does he let him do anything? Plus Ms. FBI shooting up as the end to last weeks episode implies she's gonna get more screen time too still.
Unless it's a two hour episode I just don't see how they can do it all.
