Two characters we thought were dead and done with are coming back during the season finale. One we’ve already been given hints to and is, as you no doubt figured out, Simone - and with an ability to boot. But the real shocker is Simone’s dad Charles Deveaux is returning as well. Here’s what Kristin had to say:

Sources tell me that Tawny Cypress, who plays Simone, is—drum roll, please—not off the show for good. Far from it! I’m told that even though she was “killed,” Simone is coming back, along with her father (Peter’s patient), in the season finale. It turns out she has abilities of her own, and as my source put it, “There are people on the positive and negative side. And Simone is on the negative side.” Oh, and according to another source, “[Simone and her father] may have some ties to some other characters that we had no idea about before.”

Not sure how I feel about Simone having an ability - especially when we were specifically told she would NEVER have an ability.

Kristin also mentions that Kring says we will get to see some back story for Sylar in Chapter 21 “The Hard Part” that may actually make us think differently about him.

According to Heroes creator Tim Kring, “We learn about his home life and where he came from, and after that episode, your opinion of him may change.”

In an interview with TV Guide, Greg Grunberg (Matt Parkman) reveals a small bit of whats to come. Doesn’t look like he, Ted, and HRG are gonna remain in custody at The Company for very long. HRG breaks them out and they go on a mission together:

With the help of Mr. Bennet/HRG, we’re all going to break out. It’s a really exciting episode and it sets us on this mission to stop Sylar and find the tracking system, because without the tracking system they can’t get to Claire, and they can’t get to me. The key to the whole thing is getting that computer and wiping it out.

Sounds like they’re gonna need Hana’s help

He also confirms what we’ve pretty much heard from various other sources about the season finale and everyone coming together:

We all come together and we have a mission, all for various reasons, and we don’t necessarily work as a “Super Friends” team, but we’re all at the same place at the same time with the same mission, and it’s just awesome. Like I worked with Adrian [Pasdar] the other day and I worked with Sendhil, people you never see me interact with ever on the show, so it’s really fun. The dynamic is exciting when we get to work together.

And lastly he further confirms that Clea DuVall (FBI Agent Audrey Hanson) will be back for the last two episodes of the season and perhaps even season two.

Audrey (played by Clea DuVall) returns in the last couple of episodes of the season, and hopefully will carry into next season.

And the folks over at Sci-Fi Wire get the scoopage on the titles for the final two episodes of Heroes Season One:

• Chapter Twenty-Two “Landslide”
• Chapter Twenty-Three “How to Stop an Exploding Man”

Included with the titles is a little bit of spoilage from the man Kring himself “The whole thing converges in New York, … and they’re all there, and all of them play a role,” Kring said in an interview at Wizard World in Los Angeles on March 17. “Even though some may feel like they’re less significant to the final event, when you analyze it, each one had to play that role in order for the final event to be solved, and so there really was a kind of destiny quality to them coming together and having each one fulfilling one thing and one specific role.”
