You Dont Know Who Your Talking To...Do You?

Dexters been going through life with a mask of a brother, a son, a friend, and a worker. He can't ever let anyone know who he really is, especially Deb. But what if someone already knows who he is? His secrets? Knows of his dark passenger? What if this person wants to work their way into Dexters life to be someone of an importance to him? Or what if this is just a game to them? Either way Dexter thinks this will be fun. He likes games.
