Stiles says, "I don't know, I can't say."
But she did say the pair were soul mates because: "She accepts him for who he is, and what he does."
Stiles joined the cast this season as Lumen Pierce, a woman brutalized by a serial killer and rescued by Dexter after he takes care of him.
According to Stiles, their attraction is based on "the interest in killing certain people."
While the actress admits to "filling big shoes" following last season's spine-tingling performance by John Lithgow, she feels her storyline went in a different direction, saying "I'm a chick, so that helped."
