The character of Sgt. Doakes is really an unlikable character, not because he's suspicious of Dexter, but because he qualifies as one of Dexter's potential targets. He's a murderer, obviously, who killed a man he caught a glimpse of and decided that he was a Tonton Macoutes from his rotation in Haiti. The guy did turn out to be who Doakes assumed he was, but he had chased him down and shot him before he could positively identify him. Doakes is arrogant and vicious in his interactions with people he doesn't know, but worst of all, he has the face of an alien who is trying, not convincingly, to pass as human.
i hope that Dexter eventually gets him on the table and into the ocean.
