Spoiler alert: Here there be spoilers. If you choose to read ahead, you might learn a few things about "Being Human."

If the apocalypse does occur in 2012, it's a safe bet that Mark Pellegrino is somehow involved.

As an actor, he has played multiple roles so significantly tied to the survival or obliteration of humanity one can't help but wonder if his agent is reading the Book of Revelation in between scripts - or if Pellegrino might actually perform on a stage at the end of the world.

Pellegrino is not a god, but he has played a few memorable ones on TV. He is respected for notable roles like Rita's wife-beating ex Paul on "Dexter"; Gavin Q. Baker, a flamboyant attorney to cops on "The Closer", a character worthy of his own spinoff; Tom Dempsey, an old-school mobster on "Castle". But the actor is better known as Jacob, the godlike protector of the Island on mythology-heavy "Lost."

Other viewers know him better as Lucifer, the fallen archangel-cum-devil on another mythology-heavy show, "Supernatural" - a role he just returned to on the February 17 episode "Repo Man" as a vision to Sam Winchester.

Still others might know Pellegrino best as Bishop, the undead (and later very dead) leader of Boston vampires on Syfy's reboot series "Being Human". In "Being Human," which airs Mondays at 9 p.m., Bishop is yet another character in Pellegrino's rogues gallery with a god complex. Bishop has designs on wiping out much of the human race, and turning the remainder into slaves.

And because death can't keep a good bad guy down, Bishop returns in tonight's episode of Being Human to torment his vampire son Aidan (Sam Witwer), who is experiencing a bit of parenting problems himself

Mark Pellegrino joined us over the phone to discuss Bishop's return, his career as angels and demons, and even his love of video games, zombies and a possible role on The Walking Dead.

Aaron Sagers: So I've spoken with your Being Human cohorts, and I heard you're a big gamer with your vampire son, Sam Witwer. Is that true?

Mark Pellegrino: Oh yeah. I'm kind of expanding my horizons a little bit in that realm. I used to be just the zombie apocalypse guy, but I'm starting to go outward into horror games and even shooter games, in general. I'm quite a fanatic about it.

Sagers: What kind of zombie apocalypse games do you really enjoy?

Pellegrino: Well, Left 4 Dead is my favorite. I like the first one the best because the characters are just pretty damn cool. I've been getting into the second one. Me and Sam play versions that are downloaded. There are these special games you can play on Left 4 Dead 2 that incorporates Left 4 Dead and those characters, and that's always really fun. [laughs]

Sagers: Are you a big fan of sort of the zombie genre in movies or just video games?

Pellegrino: I do like the zombie movies! In fact, I'm wearing a shirt right now my son gave me that says "Z-E-A: Special Agent, Zombie Emergency Agency." It looks like an FBI logo, but it's got all the bells and whistles of zombies. Yeah, I do like the zombie movies quite a bit. I know there are purist zombie guys that don't like the running zombies, but I dig the infected thing. I think that's a scarier incorporation of an element into the genre.

Sagers: Well, it's funny. I could see you actually fitting in well with The Walking Dead folks. Has there been any talk of that?

Pellegrino: Well, you know, first of all, I read every single one of The Walking Dead graphic novels. Twice. And Sam Witwer, is friends with Frank Darabont. So one evening, I was over at his house, we were playing zombies, and he said, "Come on, I want you to go to dinner with me." He took me to dinner, and in walks Frank, and we all sat down and ate together.

You know, it seemed at the moment at that time that there was a possibility of me going in to work for the show, but you know, of course, things happened with Frank and the show. Who knows where I stand now? I have a good friend who works on the show, too, so maybe one of these days I'll get to be a survivor.

Sagers: Who do you know who works on the show?

Pellegrino: It's Jon Bernthal who plays Shane.

Sagers: Now there are rumors that it sounds like Jon Bernthal is maybe out of the show, right?

Pellegrino: Really? I haven't spoken to him in a little while. I saw him at the premiere, but I haven't spoken to him in a while. It looked like the show was going in that direction. I think he knew that kind of from the beginning. I don't think that's a new development, unless you know something I don't.

Sagers: Everyone seems to like zombies for different reasons. What is your connection or theory as to why they are popular?

Pellegrino: There's a lot of speculation on what the zombie apocalypse thing means. I have a feeling that it's kind of an expression of our subconscious fears. I think we know that something big and impossible - some enormous crash, equalizing crash, whatever - may be coming around the corner. I think that that is a specter that finds some psychological release in these zombie movies.

I also kind of have a different interpretation than even Romero, the originator of series, would have. I think we kind of live in a bit of a cannibalistic society. Subliminally, the movies show the cannibalism of the many against the few. You know, we kind of have an ingrained, parasitic society. We kind of think it's okay to eat your neighbor.
