With 'Dexter's eighth season to be the last for Showtime, fans have no doubt begun taking stock of characters who might bite the big one before the end. The recent teasers and poster have certainly bolstered faith in the idea that Dexter Morgan himself would get his comeuppance in the end to wind up under plastic, but will Deb finally go off the rails this year? Check out the latest 'Dexter' final season preview inside for a clue!

'Dexter' fans well know that the DNA of the series itself changed in the last two years, bringing Deb in on her brother's nocturnal activities, and even reluctantly joining in season 7 finale "Surprise, Motherf---er!," but how long can Deb keep it together? The latest previews have shown Deb going off the rails a bit, worried she shot the wrong person inside that fateful trailer, but a new behind-the-scenes promo for season 8 confirms that the Deb we know has been all but "ruined."

Elsewhere, ‘Dexter’ season 8 will feature appearances from returning Yvonne Strahovski‘s Hannah McKay, ‘24‘ villain Julian Sands as a wealthy international businessman, ‘One Tree Hill’s’ Bethany Joy Lenz as Dexter’s new neighbor Cassie, ‘Last Resort‘ star Darri Ingolfsson as her antique-dealing love interest, ‘Entourage‘s’ Rhys Coiro as a bail jumper on Deb’s radar, ‘The Walking Dead‘ star Nick Gomez as a hitman that goes up against Deb, Charlotte Rampling as criminal profiling neuro-psychiatrist Dr. Evelyn Vogel, and ‘The Boondock Saints’ star Sean Patrick Flanery as ex-cop-turned-private-eye Jacob Elroy.

So, what do we think? Has Deb come too far for redemption? Will 'Dexter's final season once again see the vulgar Morgan end up on Dexter's table? Watch the video below, and judge for yourself! Will you tune in for the June 30 premiere of 'Dexter's final season?
