When we last left off with Showtime’s hit drama series Dexter, the titular serial killer was caught in a rather precarious position.  Though season six as a whole left much to be desired, the cliffhanger hinted that producers were taking the show in an exciting direction for season seven.  The upcoming season may or may not be the second to last installment of new episodes for the series (producers are keen on ending the series after season eight, but Showtime is hoping they’ll stretch things out to nine), so fans are hoping for some major developments in the new season.  The first poster and a batch of new images from season seven have been released, with the tagline on the poster offering a tantalizing clue as to where things may be headed.  Though a certain romantic subplot has me wary about how the story might play out, I'm hopeful that producers can bring the long-running series to a strong conclusion.Hit the jump to take a look at the poster and images, which give us our first look at new cast members Yvonne Strahovski, Ray Stevenson, and Jason Gedrick.  Dexter season 7 premieres on Sunday, September 30th at 9pm EST on Showtime.Via THR.
