Showtime released the first sneak peek at season 8 of "Dexter" confirming that it will be the last for the series.
In the clip, Debra (Jennifer Carpenter) is having a major meltdown, avoiding her serial killer brother Dexter (Michael C. Hall) and drinking beer in a grocery stores.
That has a lot to do with her actions in the seventh season finale.
"Dexter" returns to Showtime June 30.
