As Dexter's wife, and the mother to his son, Julie Benz plays more of a role on season four of this Showtime hit than ever before.

That's fine with the actress, who told Cinemablend she wondered "who should would have to kill" in order to be cast as Rita on Dexter after she originally read the pilot script.

Among other topics covered in the interview: her character's role this season; and the shocking conclusion to come. Here are a couple excerpts:

On Rita's role: At the beginning of the season we see Rita has it all. I mean, she has everything she’s ever wanted. She has the perfect husband, the great kids, the new baby, the dream house in the suburbs but you know, just like anything, nothing great lasts forever. We have an amazingly shocking ending this season. I mean, it’s so shocking that – it’s just shocking is all I can say. It shocked the whole cast.

On upcoming storylines: I don’t want to give away any spoilers but you know, you definitely see worlds collide; everybody’s world collides in this season.
