Just watching this week's episode now. The end to the season feels fairly predictable to me, though I'm probably way off and wrong about 93 times a day. The babysitter, what's his name's sister, will be the final girl kidnapped. Otherwise, what's her purpose in the show? Why have her in particular be the babysitter? EJO will see her relationship with Dexter as a sin, Bogart her, she'll be tied to the floor of the church or some ****, Dexter and the girl's brother will be racing against time to save her, and they either will or won't.
At the end of the day, while Dexter has questioned his own lack of faith and perhaps started to see the light, the darkness will overwhelm him, he'll see that people are who they are, and while there is goodness in the world, he has to continue doing his deeds to keep the world safe from the monsters out there. Or some ****.
