Check out 'Dexter's' new sexy, creepy Season 7 photos!

hall-carpenter-sheet-dexter.jpgShowtime is amping up our excitement for "Dexter's" return with a new set of promo photos for the explosive seventh season.

In the creepiest picture of the set, Dexter ( Michael C. Hall) and Deb (Jennifer Carpenter) are separated by a translucent plastic sheet. This appears to be a throwback to Season 5, when Deb discovered Dexter and Lumen ( Julia Stiles after they'd dispensed with the nasty Jordan Chase ( Jonny Lee Miller). The plastic sheeting separating the cop and the killers was slightly more opaque, so she couldn't identify them...and she let them go.

"Maybe it's true some people deserve to die, but I'm a cop and I don't f***ing make that decision," Deb told the pair. "So I'm going to call this in and in an hour this place will be swarming with police. If I were you, I'd be gone by then."

It's unclear (get it?) whether Deb will be quite so accommodating this season, but the fact that she has romantic feelings for her brother certainly complicates matters.
