Waiting for season 6 of Dexter is murder, but here’s something to tide you over — a first look at an image from the first episode! (We pause for a SPOILER ALERT.) Witness blood splatter analyst/serial killer Dexter Morgan (Michael C. Hall) squatting by a stitched-up corpse while preparing an evidence bag of… baby snakes? "That is the first mysterious kill linked to Professor Gellar that’s going to cross Dexter’s path and let him know that he’s up against a killer, the likes of which he hasn’t seen before," exec producer Scott Buck tells EW, referencing the charismatic religious studies professor that will be played by Edward James Olmos. "This is a person who’s sending out a message, and Dexter can’t wait to figure out what that message is."
