WARNING: SPOILERS AHEAD!
Season six of Showtime's hit crime drama ended with a monumental moment between Dexter and his sister Deb!
If you're still catching up, DO NOT read any further, because she walked into the scene just as he was driving a sword through his latest victim.
Fans will be waiting until September 30 to find out how she reacts to her adopted brother's killer instinct, but a new promo (above) hints how it will go over.
A philosophical voiceover from Michael C. Hall reveals that, "Truth brings light. It's the lies that live in darkness."
Do U think TV's favorite antihero will walk into the light next season? Or will his habit cast him further into the darkness?
