I know many of you have probably already finished Dexter, but I'm currently watching it. So, I finished Season 4 3 weeks ago (currently in season 7), and Rita died in the end. I feel like Arthur didn't kill her. Here's why:

Arthur looked up Dexter's home address and only found Deb's. How did he know where he lives. Secondly, how did Arthur know Dexter's childhood story, and that he was traumatized as a child by seeing the death of his mother and being washed in blood. There is no way it was a coincidence that Harrison was there on the floor with the blood just like Dexter. Also, how did Arthur even have time to kill her? He must have woken at least 3 hours after Dexter put him to sleep with the injection thing, and apparently he went directly to his house to get all the valuable things and then he went directly to the carnival thing. And how come when Dexter was killing him, he didn't say anything about it? I guess if I was about to be murdered by a guy who I just killed his wife and he didn't know, I would at least tell him.

What do you guys think?
