^^ I believe that it will. If I may offer future predictions:
During the entire series most of Miami Metro homicide seems to, at one point or another, express frustration over how the prosecution process fails justice. People walk free, etc. This was highlighted at the start of the series. So as for the continuation I could see Deb keeping Dexter safe from her knowledge of his activities from the beginning (she will freak out a bit over the continuation from tonight's finale) and likely see and even support his point of view. He can claim that Tom Hanks Jr. threatened to kill Harrison, but Deb is sharp and she'll see the kill room and cut on the face and put it together that Dex has more than a passing interest in all this. That's her job. I hope Dex comes clean with her from the start, rather than waste a whole season on her learning everything bit by bit. Though it will probably push her over the edge and cost her her job. One by one, Quinn, Angel, etc will become privy to Dex's killings of evil people as he continues to need his job to support his serial killing through the blood lab, etc. LaGuerta is evil IMHO and she and the captain will try and bring them all down. I'm interested in where that story resolution with the dead hooker will go. I do envision the end of Dexter as a series with him escaping to some foreign country, vowing never to kill again (thought it will end with a will-he or won't-he). I think it's going to be like the vague Sopranos finale in a way, though I hope it's not. I hope Dexter will get a film finale.
I think this finale had the most left hanging. The hand in the box is another item for the list, along with the creepy video game dude. I thought his game was cool, though I missed out on the link from it being a crime-solving game to becoming a serial killer game.
How is it that we don't have a proper serial killer video game anyway? Sandboxers like GTA and assassin missions don't count. What makes Dexter remarkable is that he generally goes after other
serial killers, which has made the story stand out from day 1. Parents groups would cry foul over the theme, but since when has that stopped a game release? Anyway, playing as Dexter would be more fun, I think.
