MySpace has an extended version of the last preview which shows a lot more stuff including a few surprises for the ’shippers. Essentially they added some more clips from Chapter 20 “Five Years Gone” in which we see President Petrelli, Matt kicking HRG’s ass, Peter flinging someone against the wall, Claire smooching with some guy we’ve never seen before (some are speculating it’s future Zach but obviously not played by Dekker), and two other characters smoochin that we never saw coming.

Check it out at MySpace or check out the YouTube version below which ANDO from 9th Wonders has slowed down a bit to see the faster clips better.

According to HeroSite.net, NBC had changed the title of Chapter 20 to “Five Years Gone” (originally “String Theory”).

The folks over at HeroSite (pays to have contacts in the industry) scored the descriptions for Chapter Nineteen “.07 Percent” and Chapter Twenty “String Theory”. Without further ado here they are:

CHAPTER NINETEEN “.07 PERCENT”

“SERIAL KILLER SYLAR’S RAMPAGE CONTINUES — MALCOLM MCDOWELL AND ERIC ROBERTS GUEST STAR — After “helping” Suresh (Sendhil Ramamurthy) search for more people with special abilities, Sylar’s (guest star Zachary Quinto) rampage continues with two “heroes” being confronted by the stronger-powered serial killer. Nathan (Adrian Pasdar) must factor what he’s learned from Linderman (guest star Malcolm McDowell) into difficult decisions that will shape the future — for him, his family, New York City and the world. As Thompson (guest star Eric Roberts) uses every tool at his disposal to find Claire (Hayden Panettiere), Linderman drafts Jessica (Ali Larter) into his far-reaching plans. Meanwhile, Hiro’s (Golden Globe nominee Masi Oka) resolve to “save the world” strengthens in the face of a grim reality. Santiago Cabrera, Noah Gray-Cabey, Jack Coleman, Greg Grunberg, and Milo Ventimiglia also star. James Kyson Lee, Missy Peregrym and Cristine Rose also guest star.”

CHAPTER TWENTY “STRING THEORY”

HAVING STOLEN THE SWORD AND TELEPORTED FIVE YEARS INTO THE FUTURE, HIRO AND ANDO BEAR WITNESS TO A GRIM, HARROWING FUTURE FOR THE “HEROES”– Thrown five years in the future, Hiro (Golden Globe nominee Masi Oka) and Ando (James Kyson Lee) discover that people with extraordinary abilities are not only widely known about — after the destruction of New York City and the deaths of millions — but are being registered, imprisoned, hunted and even killed as “terrorists.” As the President takes his first step towards a “final solution,” the pair get swept up in what could be the “Heroes” final battle and encounter a range of new and darkly familiar faces. If they survive the experience, can they still get back to the present and save the world? Santiago Cabrera, Jack Coleman, Noah Gray-Cabey, Greg Grunberg, Ali Larter, Hayden Panettiere, Adrian Pasdar, Sendhil Ramamurthy, Leonard Roberts and Milo Ventimiglia also star. Stana Katic, Jimmy Jean-Louis and Zachary Quinto guest star.

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.
