With just two seasons left for Showtime's long-running drama, Dexter, the network has just debuted a new teaser trailer for the show's seventh season. According to Digital Spy, this year's batch of episodes will directly build off of the end of season six when Dexter's sister, Deb, discovered him committing a murder. This will be the penultimate season of the show, so fans of the series can expect plenty of shocks along the way as we count down towards the end.
Season seven of Dexter will premiere on September 30.
