After a short amount of looking, Dex finds a small notebook. Suddenly, Harry is there telling him to put it back, end this. Dexter asks why and he says that he didn't teach Dex the Code so that he could teach his friends. He taught him so he could stay alive. He says that Dexter doesn't get to have friends -- nothing good can come from this. From the other room, Miguel says that he doesn't think that anything good could come from this. So, Dexter shows him the notebook. Take that, dead dickalicous dad. I'm sorry, sometimes I can't stop thinking of him as that guy. Dex VO's that it's his life. He and Miguel decide that they'll go forward, if the blood on the bat matches the blood of the victims.
