Tim Kring revealed, via /Film, that Heroes Reborn will continue in real time, following the events of Heroes. If the show had continued on past its fourth season and lasted ten years, that tenth season would premiere in 2015. So, rather than the new series feeling like season 5 of Heroes, it will feel like season 10:
“I know that sounds a little provocative but the point is, one of the things that we talked about at the very beginning in the writers room was how we wanted every single bit of the mythology to feel as though there was a continuum from the show, and the show picks up five years later. So, ergo, it would be five seasons later and this would be season 10. That was the thinking.”
Heroes Reborn premieres September 24th, 2015 at 8/7c on NBC.
