This week's Entertainment Weekly has a good article previewing the new season and it gives some tidbits about what will happen. Among them:Click to see Spoiler:John Lithgow will play the new "big bad" - a serial killer that Dexter may or may not form a friendship with. I loved his as a killer in Blow Out (still one of my favorite movies), so I'm excited to see him this season.
Keith Carradine will be back, but Deb has moved on. It'll be interesting to see how the dynamic has changed between them now that she's not single.
I'm so excited for the new season!
