Dexter - Season 7 - Interview with Jennifer Carpenter

Thanks to maplewhite1912 for the heads up.

Deb has uncovered everything! What's her first reaction in the second episode?
Jennifer Carpenter: I think audiences, especially our Comic-Con audience, wanted to me to say, "Oh, she'd rage or explode or fire a round from her gun," but all [her] senses are firing and [her] brain is kicking up. I have this written history with this character for seven years, and there's landmines everywhere. It's rich. It's dangerous for everyone involved. There's no such thing as a filler scene this year. Everybody is involved in a weird way.

The Ice Truck Killer hand was on the table. What's going on inside her head as she makes these connections that Dexter was present when she was on the Ice Truck Killer's table?
Carpenter: It's too hard to process it all at once. All of those things were in the room at the time, but that realization that those things are connected has its own turn. There was a moment when I was scanning the table while filming and thinking, "That sucks." At some point, your body just can't play Tetris anymore and find room for everything. There's some paralysis that takes over, like, "I'll get to that in a minute."

How does Deb finding out that Dexter is a serial killer change her as a person?
Carpenter: Instantly, the fantasy of being in love with this man falls away, or at least is snuffed out. It's a slap in the face that wakes her up in a weird way. Suddenly, she can see all the manipulation and redirection that he's handed her. It's changed everything. It's made her job so hard. In a weird way, I think I was afraid it was going to paint us into a corner when she one day found out, but it's endless space to work in.
