"Heroes Reborn" Episode 4 airs Thursday, and judging by the show's latest promo, viewers may see the return of fan favorite Hiro Nakamura (Masi Oka) in the upcoming episode.

A teaser for the fourth episode, titled "The Needs of Many," shows Noah Bennet (Jack Coleman) arriving at Hiro's doorstep. The hero from the original series seems to have aged quite a bit, judging by the gray streaks in his black hair.

It's possible that Hiro's frequent time jumping has altered his appearance. Or Hiro may have chosen to settle in an earlier time period. This could fit with fan theories that the teenage Miko (Kiki Sukezane), who is currently in the possession of Hiro's old sword, is somehow the biological daughter of the time shifter.

Hiro also seems surprised to see Noah, as if it's been years since their last meeting. This would dispute Noah's theory that Hiro was present with him at the hospital a year before, as suggested by the time skips in the security footage Noah watched in last week's episode. Could there be another time manipulator out there?

The promo also shows that Tommy (Robbie Kay) is alive and well after the car crash, though it's uncertain if his mother was injured. Another scene shows Emily (Gatlin Green) and Brad (Jake Manley) with a bandaged Tommy at what looks like a hospital, so it's likely his mom may have been hurt too.

Luke (Zachary Levi) looks like he is continuing to struggle with his heat-based powers, and Carlos (Ryan Guzman) is bouncing back from his recent fight with strongman Captain Dearing (Dylan Bruce). Malina (Danika Yarosh) and her now visible mentor once again tease viewers with some ominous approaching event, and the villainous Ranautus CEO Erica Kravid (Rya Kihlstedt) explains to her daughter why abducting Evos is necessary "to save our species."

A line from Molly (Francesca Eastwood) also hearkens back to the orginal show's tagline: "Save the cheerleader, save the world." She advises someone, likely Noah, to forget about the past. "Save the future," she says.

"Heroes Reborn" airs Thursday at 8 p.m. ET on NBC. Check out the next episode's promo below:
