Season 6 of Showtime's long-running "Dexter" ended on a cliffhanger with Dexter (Michael C. Hall) being caught by his own sister, Deb (Jennifer Carpenter).  

Fans were left wondering how Deb would react and, more pressingly, just what extremes Dexter would go to in order to carry on his moonlighting gig as a compulsive  serial killer. 

A new preview, released today, gives viewers a peek at what will happen in the following season. Even with his secret out, Dexter is still Dexter, after all. As he stresses in the preview, "I need to be who I am!"

Watch the preview here:



The show also stars Desmond Harrington, C.S. Lee, Lauren Vélez, David Zayas and James Remar. Season seven guest stars will include Jason Gedrick, Katia Winter and Santiago Cabrera, and special guest stars Ray Stevenson and Yvonne Strahovski.

The new season premieres on Showtime on September 30 at 9 p.m. ET/PT.
