This is it! We've only got 4 more episodes of 'Dexter' left! And episode 808 "Are We There Yet?" ended on quite a shock. Looks like the brain surgeon isn't quite finished yet, nor is it the person that Dexter and Vogal initially thought it was. Below we've for the teaser for this upcoming Sunday's episode "Make Your Own Kind Of Music" along with 2 new clips. In the first clip, Dexter warns Hannah about a Federal Marshal that is tracking her down. In the second, Debra learns about Zach's death. The new episode airs this Sunday August 25th only on Showtime. Read Alsye's TV recap of "Are We There Yet?"
