The exciting teaser for the next episode of "Heroes Reborn" has aired, and it promises "the biggest revelation of the season."

That news should come as a relief to many "Heroes" viewers frustrated by the many mysteries thrown at them throughout the series' first six episodes. What happened to Claire Bennet (Hayden Panettiere), and how could she possibly have been killed? What did Mohinder Suresh (Sendhil Ramamurthy) have to do with the explosion? Who is Tommy Clark (Robbie Kay) really, and how is he going to save the world?

Last week, fans finally got the answer to one of their most common questions: When is Hiro Nakamura (Masi Oka) going to show up?

A fan favorite from the original series, Hiro was finally freed, and now he intends to travel to the past with Noah Bennet (Jack Coleman) in order to change the future. While the prospect of time travel always threatens to confuse the plot, a visit to the past should definitely shed some light on the events of June 13.

"This time you will save the cheerleader," Hiro tells Noah, alluding to an important plot point in the original series. "I will stop the bomb."

The next episode also marks the reappearance of Mohinder and Angela Patrelli (Cristine Rose). The promo also hints that Claire could potentially make a surprise cameo, though showrunner Tim Kring had previously said Panettiere would not be returning.

Panettiere herself told Cosmopolitan in an interview last year that she had nothing to do with the new series.

"It's a little bit of an interesting feeling because you go, 'That was our show, our home, our family,' something that we had a major part in creating as well, and, I mean, I hope that they don't have somebody else playing our characters, that would be a little dagger in the heart. But, you never know. I wish them success in it, for sure," Panettiere said.

If Claire does appear in the show, it will be a major surprise.

"Heroes Reborn" airs Thursday at 8 p.m. ET on NBC. Check out the promo below!
