Showtime has finally made it official: Dexter Season 8 will be the swan song for this long-running drama.

Along with confirming the long-gestating rumor, the network has also released a two-minute clip from the June 30 premiere, which makes it very clear Deb is unhappy both with her actions on the Dexter Season 7 finale and with her brother in general.

Watch her go on on him now:

Not much is known about the upcoming final season, except that Yvonne Strahovski will be reprising her role as Hannah McKay.

So it looks like Dexter will have two women in his life, neither of whom are his biggest fan.

UPDATE: Says David Nevins, President of Entertainment, Showtime Networks Inc., in a statement:

"DEXTER is a landmark franchise for our network, and we cannot wait to unveil the conclusion of this series, as we know it, to the millions of passionate fans who have supported the show season after season. We'd like to thank Michael, Jennifer, and DEXTER 's indomitable cast, executive producers, writers and crew for eight incredible seasons."
