OTRC: 'Dexter' final season 8 spoilers revealed by Michael C. Hall, others

'Dexter' star Michael C. Hall talks to OTRC.com about the eighth and final season of the Showtime series and about his character's challenges. He made his comments at the June 2013 premiere.

The eighth and final season of the Showtime suspense series "Dexter," starring Michael C. Hall as a serial killer and Miami Police Department blood spatter analyst, is set to premiere on June 30 and he and several other cast members spilled to OTRC.com all sorts of juicy spoilers about what fans can expect.

Spoiler alert!

The cast, including newbie Sean Patrick Flanery (see details about his character and an exclusive interview with the actor from April), talked to OTRC.com at the season 8 premiere of the show earlier this month.

1. Dexter's challenge - the (classy) Dr. Vogel

"We've got the wonderful Charlotte Rampling, who plays Dr. Vogel. She just brings a lot of class to our show and she's wonderful and she's going to be in it for most of the season," David Sayas, who plays Sergeant Angel Batista, told OTRC.com.

He is referring to a new character that is brought into the Miami Police Department as a consultant -- she is a scholarly expert about serial killers. Not exactly an ideal colleague for Dexter, whose No. 1 rule is to keep his outside-office activities a secret and already has to deal with the fact that his sister can't deal with the fact that he's a serial killer.

2. Dexter's "a bit of a mess"

Dexter and his sister Debra, his boss at the Miami Police Department, have to deal with the aftermath of the death of Lieutenant LaGuerta. Debra shot her in the season 7 finale.

"I think Dexter, when we met him at the beginning, was a completely compartmentalized, easy-breezy killing machine and now he's a person for whom all those lines have been blurred and he's a bit of a mess and he's trying to maintain some sense of control and honor and appetite for humanity that he didn't once know he had. But being human hurts, you know?" Hall told OTRC.com.

3. Brace yourself for a darker Deb

"You start season 8 six months after the container scene. Everyone's going through their version of coping and adjusting to the loss of LaGuerta and Debra's not doing it very successfully," Jennifer Carpenter, who plays Dexter's sister Debra, told OTRC.com.

She added that her character will showcase a darker personality this season, "certainly in the beginning."

"That was really difficult to try to navigate how to play that in an honest way but it all unfolds pretty naturally and one link leads to the next and so, it makes for a really nice experience this season," she said. Debra, by the way, gets involved with a new man, played by Sean Patrick Flanery.

"She's killer. I'll be honest. She's one of the better actresses I've ever worked with in my career and I've been doing it for about 25 years. It's an honor and it's a pleasure. There's no drama. She's already thought about it -- when she shows up on a day, she knows exactly what she wants to do. It's a pleasure. I wish I could have done eight seasons."

4. Masuka's past will be revealed

"We're going to learn a little bit about his past. He's gonna be visited by his past, which is gonna be a lot of fun and exciting and new and different," said C.S. Lee, who plays the funny, somewhat perverted lead forensics investigator Vince Masuka.

Lee added that viewers will discover that Masuka is a romantic.

"I have always thought he was a romantic at heart, just from the beginning," he said. "I think this year, especially, you're gonna see that he is romantic at heart and behind all those bad words, those naughty words, he's just a big-hearted guy."

5. Harry's role is changing

"We're moving towards Harry playing as his own voice," James Remar, who plays Harry, Dexter's late father, told OTRC.com. "And the complexity of Dexter's imagination becomes more real and whatever your figments are -- they become more real. We get to play it in a more conversational, realistic way."

"Rather than me just standing under a light and being a ghost, I'm becoming more of a person. In keeping with what's revealed in the conversations that I've had with Dr. Vogel ," he said. "So I don't wanna reveal too much but we do see .. Harry having conversations with someone other than Dexter and Deb in real life. So we get to see what the character of Harry ... what he was like."

6. Hannah's back.. beware, Dexter

"I can't believe I didn't die. It's kind of like, 'winning!'" Yvonne Strahovski, who plays Hannah, Dexter's season 7 love interest and serial killer groupie, told OTRC.com.

She said "Hannah comes back to stir it up a little bit" in season 8.

7. The season 8 premiere left "Jamie" breathless

"I didn't breath and I couldn't put it down," actress Aimee Garcia, who plays Jamie, Angel's sister and Dexter's son's nanny. "The messenger came to drop it off and I essentially just snatched it from his hands. I think I probably gasped out loud and said, 'Oh my God,' which is not rare on a show like this." Jamie, she said, will also go through a transformation in season 8.

"The great thing about this show is that every character has an arc, so things affect her that changes her forever," Garcia told OTRC.com. "I think she becomes more and more like family. She kind of goes from employee to almost more of a familial role so it just gets tighter and tighter 'cause, of course, he trusts his most prized possession with her, which is his kid."

The eighth and final season of "Dexter" premieres on Showtime at 9 p.m. ET.
