Not so much myself, it was hinted at quite frequently that Conrad framed David on behalf of a sinister organization or group of people that I felt was never explored enough. I don't feel like there's been enough resolution regarding the overarching story but w/e.
The execs are still holding out hope for a renewal but it's very unlikely. Good thing they've known for a while though, at least we'll get somewhat of a proper conclusion. And also they're probably gonna kill off another 8 or 9 characters, so I'll be preemptively no longer watching this show goodbye.
