On this week's third season finale, Sylar died. For the most part.

Nathan also died. Kind of.

Now, the pair share one body, as Sylar has been brainwashed to believe he's actually Nathan. Following along? Adrian Pasdar is, and he's thrilled with the direction of the show.

"Zach's not done," the actor told TV Guide. "There's Nathan, there's Sylar, and there's the point of view that you have to factor in. If I look up into the mirror, who would I see?"

Looking down the line, the storyline sets up an epic internal battle between Nathan and Sylar next season.

"Who's going to be able to control the actions of the body?" Pasdar asked. "Like one of those computers that self-teaches, the longer he stays in my body and the longer he assimilates my physical structure and DNA, the more control I get. So it becomes a battle of who's in charge."

But what about the fact that no one ever, actually dies on the show? Doesn't that remove any and all drama?

"Some things should stick, otherwise there's no weight if you're going to reset everybody's history every 10 minutes, and nobody's going to pay attention anymore," Pasdar said. "But as fascinating as concepts might be, ultimately it's people that engage viewership. If you're going to ask people to tune in week to week, you want to follow somebody's plight, not some nameless story arc. We've tried to be consistent - sometimes you win, sometimes you lose. But I think we're going to come out on top."
