Heroes writer/producers Aon Coliete and Joe Pokaski told fans at Comic Book Resources the name of the show's fifth "volume" (Following season 1's "Genesis", season 2's "Generations" and the third season's "Villains" and "Fugitives"):

[C]urrently, it is called "Redemption." All we can tell you is that act five of our "Fugitives" finale will give you a look at what it will entail.

That last part's no surprise - the final act of the final episode from each volume to date has been the first chapter of the next volume, after all - but "Redemption" is a telling title, considering the way that the current volume is trying to set up moral shades of grey for almost all involved. Will we be seeing Nathan, HRG and other characters involved with the hunting of Heroes face up to their methods, Sylar going good (again), or Peter and pals dealing with the metaphorical blood on their hands from their somewhat substandard freedom-fighting techniques...? Or all of the above? You'll only have to wait until the end of this season next month for your first hint.

According to Kring, the much-publicized third volume, "Villains," will only last 13 of the third season's twenty-five episodes, after which the show will immediately begin its fourth volume, to be called "Fugitives." The fourth volume is expected to run twelve episodes through to the end of the third season. No plot details were given about "Fugitives," but given the show's love of ripping off - I mean, "paying homage to" - old X-Men comics, don't be too surprised if you see the main characters having to go on the lam from some official governmental attempt to seek out and destroy everyone with superpowers following an attempt to save the world gone horribly wrong.

Kring also mentioned that the second half of season two, which was never filmed due to the writers' strike, would have been called "Exodus." And he said we won't learn any more about Kaitlin in Volume 3, but we will see more of Echo, the loud shouty postal worker from the webisodes. And the show is hoping to get invisible man Claude (Christopher Eccleston) back, as soon as Eccleston's schedule works out.
