I honestly have no idea where they will go, as the Governor last season was a paper thin version of what he was in the comic. Michonne basically stuck a spoon in his ass, then scooped out his eyeball with it, after removing it. Also nailed his dick to a board. All because he continually raped/beat her while he held her prisoner. The way they ended the Governor story, was more in line with the comic. With that said, Negan is the next big bad and he makes the Governor look like Jesus.
