'Dexter' Season 6 video: Alpha and Omega

Showtime is dropping some delicious teaser clips for the upcoming season premiere of "Dexter." First we saw Dexter in a warehouse area, having been stabbed. Now the Miami Metro Homicide cops find a body washed up on the beach.

Omar Rivera is found with a weird series of stitches on his chest - the Greek letters Alpha and Omega, which of course Quinn knows because he dated some sorority girls. Yeah, we're sure they sat around teaching him the Greek alphabet.

But the weird doesn't stop there - something under the stitching is moving. And Dexter is about to cut it open and see what's inside. *shudder*

"Dexter" premieres Sunday, Oct. 2 at 9 p.m. ET on Showtime.
