4. Batista Is Now Lieutenant
When we last left Batista he was throwing a retirement party and had just purchased a restaurant. Everything seemed to have a happy ending for Batista and no one deserves a happy ending more than he does. The death of Laguerta changed everything. Batista has chosen to come out of retirement and fight crime once again with Miami metro. Obviously he is now back on the police force and due to the departure of Deb he has recently been promoted to Lieutenant. Batista has always seen the good in people but at some point that will most likely change. Angel Batista doesn't have the police instincts that Laguerta did but one has to assume at some point he will stumble upon some sort of clue that Dexter is indeed a killer. He has spent the entire course of the show being completely oblivious to the fact that Dexter is a serial killer but it's safe to assume that at some point his eyes will be opened to the true face of Dexter.
