We're going to get used to the idea of 'Dexter's final season sooner rather than later, now that Showtime has officially announced that season 8 will be the last year for Miami's favorite serial killer. The final season will premiere on June 30 along with 'Ray Donovan,' but what about the newest 'Dexter' teasers have us fearing for both Dexter and Deb's lives? Get the latest sneak peek inside!

'Dexter' has almost always been able to keep his friendly mask in in place, but the latest pair of teasers (courtesy of Vulture) remind us just how much Dex and Deb have changed, and how much darker they've grown over the last eight years. Cut in the style of the classic "photo-a-day" videos, the latest look into 'Dexter' season 8 ominously teases that either Dexter or his sister could come to their dead ends on a table sooner rather than later.

New footage or no, ‘Dexter’ season 8 will feature appearances from returning Yvonne Strahovski‘s Hannah McKay ‘One Tree Hill’s’ Bethany Joy Lenz as Dexter’s new neighbor Cassie, ‘Last Resort‘ star Darri Ingolfsson as her antique-dealing paramour, ‘Entourage‘s’ Rhys Coiro as a bail jumper on Deb’s radar, ‘The Walking Dead‘ star Nick Gomez as a hitman that comes to tangle with Deb, and ‘The Boondock Saints’ star Sean Patrick Flanery as ex-cop turned private-eye Jacob Elroy.
