Re: Dexter Season 7 (spoilers)
A 2 season arc of Dexter's paranoia spiraling out of control, leading to his eventual demise wouldn't be terrible though. This isn't the last season, next is, so things can't come to a conclusion too early. Unless they Russo us and end it a season earlier than announced, which could be awesome as well.
Deb seems to be getting increasingly out of her mind as well.
