Well, folks, Heroes has done it again. Nathan Petrelli may have expired with a glorious, gurgling coda, but his character lives on — thanks to Matt Parkman — reincarnated inside a mind-wiped version of arch-villain Sylar. While the closing moments of the Season 3 finale suggest that Sylar's presence still lives on in "Nathan," have we seen the last of the furry-browed Sylar we've always known?

"Zach's not done," Adrian Pasdar tells TVGuide.com. "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?"

Naturally, the twist sets up an epic internal battle between Nathan and Sylar in Season 4... read more 30 Comments

As Heroes enters its final three episodes of the season (Mondays at 9 pm/ET, NBC), the lines are (literally) being drawn for a multi-hero crossing of paths at the mysterious Coyote Sands. But will this creepy burial ground become the new Kirby Plaza?

"Everybody does come together at Coyote Sands," Greg Grunberg tells TVGuide.com. But after last week's reunion with the son he never knew he had, Grunberg's Matt Parkman will have a whole new set of priorities in the remaining episodes and beyond.

"The baby and his family is the reason Parkman is going to do something in the last episode that he may regret for the rest of his life," Grunberg says. "It's a huge story that we play out — something that only a guy who's been pushed and is desperate to save his family would ever do."

As Heroes' Matt Parkman, Greg Grunberg can control people's minds and create fantastical realities in their heads. Grunberg's son has shown in his battle to overcome epilepsy is no fantasy at all.

Grunberg's 12-year-old son, Jake, has lived with the struggles and seizures epilepsy causes, but thanks to a recent brain surgery, he is showing massive signs of improvement.

"He's doing really well," Grunberg tells TVGuide.com. "You don't try brain surgery until you've basically run out of medicine. There are so many things you try before you get to removing a piece of his brain. But they saved his life."

Grunberg says surgery became an alternative when doctors were able to pinpoint the area of the brain with the most epilepsy activity. Now, he says his son is "90 percent better" and that he is hopeful for his future. "He's living a normal life — he's not seizure-free, but he's back doing what a normal kid would do," he says. "I'd love to see Jake not have epilepsy for the majority of his life, and I think that's going to happen with what they're doing."

Greg Grunberg plays a mind-reading ex-cop on Heroes, but some overeager fans may have worked themselves into an unnecessary frenzy by trying to read the actor's mind.

Grunberg sent a message to fans via his Twitter account Sunday that caused many to fear the show was ending after its current season. "Winding down shooting Season 3 Heroes," he wrote. "Tough to say goodbye to crew not knowing if any or all of us will return next year. Hope all."

The firestorm the comments caused quickly ... read more 36 Comments

"The government gets involved with taking people like us down and capturing us," Panettiere says in the video shown below. Ultimately, after what Grunberg describes as "a huge cliffhanger," the hunted heroes are afforded a chance to elude capture.
