Okay, so truthfully, this photo from the next season of Dexter doesn't tell us much. We can see Dexter Morgan (Michael C. Hall) examining a body and saving what looks like it could be a baby octopus (because seriously, what else could that be?) as evidence, which is pretty much the only item in this photo that is something we haven't come to expect from the Showtime show. Yeah, Dexter examines dead bodies. With gloves on. In Miami. Cool. Even so, I'm sure you can try and strain your eyes to determine the nature of that dead guy's wounds and figure out if there's some sort of correlation between the tiny baby octopus-squid-snake, but you should probably just chill out and take it for what it is: a glimpse at the new season of Dexter! Woo!
