Yeah this would be good. However I have a strong feeling its going to go with a sacrificial ending. Dexter will probably sacrifice himself to save Harrison at the end. After all the people he got killed and how hes ultimately fucked up everyone who was ever close to him, the one thing he truly wants is to be a good father. But hes fucked that up too and already put Harrison through so much, and surely Harrison will endure even more as the show progresses. In the end, the only way Dexter will feel like hes able to atone and be a better father, is to save Harrison in some final confrontation with a killer or the police etc by getting himself killed. Preventing Harrisons death, or his arrest by taking the fall and dying removing himself from the possibility of ruining any more lives. But this would feel a bit cliche and predictable. The best endings are when they do something you didnt even know you needed to see. I hope they surprise us in a good wayheres to hoping.
