SyFy Portal made an interview with Tim Kring, Creator of Heroes. He cleared somethings about deaths and season finale…

“When you have a villain as vicious as Sylar, some characters have to pay the ultimate price,” Kring told TV Guide. “We’ve set the bar high as a show that plays truthfully with the audience — and we have to keep delivering on that.”

“The entire cast knew going into ‘Heroes’ that story is king,” he said. “There’s a whole new season with a whole new concept coming, and Isaac was in the way. Ironically, his ability to see the future was pretty limiting — he had to be in his loft to paint and manifest his power. He never left the building except for that dream sequence where Peter explodes. With a show as sprawling as ‘Heroes,’ that’s a problem.”

Anyway, what should fans expect in the final episodes that are airing in the next month?

“We love our shocks and surprises, but we also honor our commitments,” Kring said. “We showed Isaac dead on the floor way back in Episode 2. Sure, we could have found a way out of that, but it’s not our style. We take story seriously.”
