(SPOILER)I hate to be the bitch of the Internet, but I am glad Rita died. I like Julie Benz, but I never liked Rita. Of course, I see the show from Dexter's perspective, so she comes off like a nag. I'm sure if I saw the episodes through her eyes it would be different. Ah well, it is what it is. She made Dexter increasingly complacent, anyway. By the finale he was ready to give up entirely. Rita needed to die to reboot it, in a sense.
I won't be surprised if we see little of Cody and Aster. Maybe the first few episodes. I don't think Dexter will keep them. Then he's stuck with a baby, which in my opinion he would be selfish to keep at all, though he will. I wouldn't mind a time jump at some point mid-season so Harrison grows up a little ;O But then viewers will feel upset they missed 6 years or so. I like time jumps and Rita death? Good thing I'm not a writer for this show or I'd sink it.
And he needs to just stop answering his phone all the time. In fact, if he had not been talking on the phone, he probably wouldn't have hit the other man's car, and Trinity would have been dead sooner, saving Rita. He should plastic up a room, strap down his cell phone, show it pictures of himself, and then stab it.
