Damn you, Dexter. You've pulled me back in. This behind-the-scenes look at the upcoming season of Dexter gives us a preview of who the players will be. We've got Edward James Olmos and Colin Hanks as a creepyreligion professor and his creepier disciple. It's not clear what their plans are but we can see that it involves big knives and the name of God. That's a bad combo. Also, joining this season is Mos (formerly Mos Def) as Brother Sam. At first he' Dexter's target before a common interest reveals itself. Miami Metro is bringing in a moody new detective played by Billy Brown. He's a no-nonsense Chicago native who sees working homicide as a business and doesn't have time for department hijinks or detectives dressing like members of Smashmouth. Boy, he picked the wrong town. And then there's Aimee Garcia, who plays Batista's hot sister and new nanny to Harrison. More importantly, she can be seen in a scene with Deb saying, "I came in here to give you a kiss goodnight. Not to look at pictures of dead bodies." A) Fire that nanny. B) Is Deb in a same-sex relationship this season? Or perhaps a polyamorous couple?? I can so see Quinn being into that. The new season of Dexter premieres October 2nd on Showtime.
