HeroSite.net has posted up the official NBC write-ups for the remaining three episodes of the season. Sadly the write-up for the season finale is not very revealing at all - but thems da brakes. Here are the write-ups:

CHAPTER 21 “THE HARD PART”

AS NATHAN AND HIS FAMILY READY FOR THE ELECTION, HIRO AND ANDO FACE THE HARD PART OF SAVING THE WORLD; ERIC ROBERTS, RENA SOFER GUEST-STAR — Now knowing what’s at stake if they fail in their mission, Hiro (Golden Globe nominee Masi Oka) and Ando’s (James Kyson Lee) determination to save the world is put to the test. Committed to the path, Nathan (Adrian Pasdar) takes some surprising steps to guarantee his election. Jessica (Ali Larter) and D.L. (Leonard Roberts) begin to learn how their family fits into Linderman’s plans. Thompson (guest star Eric Roberts, “Less Than Perfect”) brings someone new into his company’s fold. With more and more blood on his hands, Sylar (guest star Zachary Quinto) visits his mom (guest star Ellen Greene).

As he prepares to face Sylar (guest star Zachary Quinto) to the death, Hiro (Golden Globe nominee Masi Oka) learns of his lineage from his father (guest star George Takei, “Star Trek”). While various “heroes” fatefully arrive in New York City, Peter (Milo Ventimiglia) and Ted (Matthew John Armstrong) attempt to leave the city before the foretold explosion. H.R.G.

Kristin ran into Zachary Quinto this past weekend and he had the following to say about Chapter 21 “The Hard Part”:

You get to see a whole other side of him [Sylar] in episode 21, which was such a joy for me to explore. You get to see a lot more about where he comes from and what drives him and what he’s fighting against in a lot of ways. I think he’s definitely misunderstood—he’s like a lost soul. And I got to work with the incomparable Ellen Greene—she might play my mom, but I’m not going to say that for sure…

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.”

HeroSite source Mr.Video has revealed that the titles for episodes 20 and 21 are:

• Chapter Twenty “String Theory”
• Chapter Twenty-One “The Hard Part”

Also the story I’m hearing is that both episode 20 and 21 take place in the future. This makes sense with the pictures of Isaac about to become a new addition to Sylar’s brain collection in episode 19 (as seen in the NBC spoiler pictures) and the spoilers that Kristin released stating that the next major Hero death is in episode 22. This seems to indicate that Isaac’s death will be a cliffhanger at the end of episode 19.
