All good things must come to an end. And if the first official, full-length trailer for Dexter season 8 is any sign of what’s to come, the fall of Dexter Morgan may soon be upon us.

In the 3-minute trailer (above), Johnny Cash’s “God’s Gonna Cut You Down” eerily plays in the background as flashes of scenes from the upcoming final season sets the tone for what will likely be one of the most suspenseful tales the series has ever seen. And if Dexter thinks that trying to control the aftermath of what occurred in the season 7 finale is going to be difficult, the inclusion of a new character, Dr. Evelyn Vogel (Charlotte Rampling), will certainly complicate matters further.

Vogel is similar to the Frank Lundy (Keith Carradine) character in that that they’re both experts of the criminal mind; however, unlike Lundy, Vogel is a neuro-psychiatrist whose expertise is in psychopaths. Lundy may have had the street smarts, but it’s Vogel who is able to dissect the mind of a serial killer with science, meaning that Dexter will have a difficult time dodging her once she has her sights set on him – which she does early on, apparently.

And if Vogel’s appearance isn’t enough of an issue for Dexter to deal with, Deb’s downward spiral surely will be. After killing LaGuerta in last season’s finale, it appears that Deb is unable to handle taking a life in the same way that her brother is, which forces her to turn to drinking, drugs and strange men to help numb the emotions she’s dealing with.

Is this Dexter’s fate?

At first glance, the trailer makes it seem as if this upcoming season will be an action-packed adventure throughout; however, after taking a look at what Vogel’s character to will bring to the series, it appears that a truly compelling exploration into Dexter’s psyche will occur, albeit forcefully.  But with Jacob Elroy (Sean Patrick Flanery), an ex-cop turned private investigator, joining the series, as well as the return of Hannah McKay (Yvonne Strahovski), there will certainly be more than enough action included to satisfy any bloodthirsty fans.

But after so many years on the air, how will the tale of Dexter Morgan come to an end? In the trailer, Deb is shown walking into police headquarters to make an official statement. Could this be the way Dexter is brought down? Unlikely – though it could be a hint at what might eventually occur.

In Dexter season 7, Deb finally realized that she’s unable to be happy with Dexter (and his secret) hanging over her head. And though she did, in fact, kill LaGuerta to save her brother, the repercussions are proving to be too great for her to deal with. Could this mean that the only way for Debra to truly be happy is to “deal with” Dexter herself, thus releasing her from his control and allowing her to be happy? We’ll have to wait and see.
