Supernatural Magazine #13 Dec 09/Jan 2010: Siren’s Call
(...) OSM: How was Nick described to you, and did they initially spell out that he was this treacherous Siren? JP: I knew during the audition process, because part of the sides {script pages use for auditioning - Ed} were for scenes after that was revealed. I believe it was in the car and then another was with the two brothers at the end. He was originally described as an FBI Agent and that weird things started happening around him.
(...) OSM: It's interesting because the Siren could have just been a bloodthirsty, needy menace, but they made it deceptive and manipulative. JP: Yeah, It could have been purely sensual, but if a creature like that had to deal with people, its instinct to receive isn't going to fly because of the way it looks. That's why it has to manipulate, and that doesn't happen anywhere else in nature. It could have been just a predatory sexual creature if it had been attractive enough that people would respond to it. OSM: Once the brothers were enthralled and the Siren's true nature was revealed, did you approach Nick's mannerisms or speech pattern any differently? JP: Yeah, at that point, I thought he should be ambiguously sexual. As the FBI Agent he was a guy's guy, but this creature wasn't a guy or a girl. I tried to find something in between and enjoyed having control over these boys in a sexual way. It's a strange way to describe it.
OSM: Considering the Siren initially appears as a female that seduced men, it was almost as if gender wasn't a factor for it. JP: Right, which is really bizarre. There had to be some way to get that across without being ridiculous. When the brothers found out I was the Siren, I couldn't keep acting like a woman and it wouldn't have been real if I kept going as a man. I tried to find something almost neutral, but displaying some kind of sexual tension. It was weird, and I don't know how I came up with that. (...)
