‘Dexter’ Season 8 Trailer: The Final Symphony Begins April 25, 2013 Dexter, News Now that Showtime has officially confirmed Dexter‘s final season, the premium channel has released a new trailer touting Dex’s (Michael C. Hall) final bloody symphony. Set against Jill Tracy’s moody “Evil Night Together,” the trailer recaps the darkest moments of the series’ past seven seasons, culminating with the shocking murder of LaGuerta (Lauren Vélez)-a murder that could very well be Dexter’s undoing, even though his sister was the one who pulled the trigger. “It’s like I’m conducting a final symphony,” Dexter says. “Requiem for demonic Dexter.” Check out the trailer below. Are you prepared to say goodbye to Dex? Let us know in the comments. Dexter season 8 premieres Sunday, June 30th at 9PM on Showtime.
