Ray Stevenson credited as playing...
Isaak Sirko
- Isaak Sirko: I was so blinded by my desire for vengeance that you were able to lead me into a trap. A mistake I assure you won't happen again.
- Dexter Morgan: We have a cartoon in America about a coyote who chases after a roadrunner. He keeps thinking that. He keeps rocket-skating right off the cliff.
- Isaak Sirko: I have a feeling that you're a different kind of animal. The question is what kind are you, Dexter Morgan?
- Dexter Morgan: The kind who hunted your friend down and strapped him to a board, and put a plastic bag on his head, and crushed his skull with a fire extinguisher. The kind who's going to do the same thing to you, give or take the fire extinguisher.
