Dexter Morgan (Michael C. Hall) and his sister Deb (Jennifer Carpenter) still have some unresolved issues in the latest trailer for Season 8 of Dexter, which Showtime confirmed yesterday will be the final season. This footage gives us our first look at Charlotte Rampling, who joins the cast this season as a neuro-psychiatrist who specializes in criminal profiling. While we impatiently wait for the Season 8 Premeire on June 30, this brief glimpse of footage makes it clear that tensions are running very high and that there is much blood left to be spilled before the series ends.
