Heroes deaths

Here is what Kristin had to say about the deaths on Heroes : "I'm highly alarmed by the body count at the end of next week's episode. If one death in particular isn't a fake-out (that is, if he or she doesn't come back when the show returns), I will be asking you to join me for the rioting, looting and hissy-fitting that is only appropriate with a death of this kind of fan favorite".
 
She adds that Claire won't be crying for long and that Alejandro's character was not designed to stay on the show as long as he did. She says "he was only supposed to be in one or two episodes. So he was living on borrowed time and should move on to greener and fan-friendly pastures".

Finaly she said that "in next week's winter finale, three Heroes will die [...] We'll call the first death Final, the second death Uncertain and the third death Reversed (thanks to Claire's miracle juice—yay!). (And no, they don't go down in that order.)

Although you may be shocked by all of these deaths—because they are all series regulars and very pretty people!—you probably won't cry over Final or Reversed (that's just my hunch). But if Uncertain turns out to stick, well, let's just say the Heroes producers best be stocking up on some hazmat suits for the s--t storm that's about to erupt! The fans will not be happy."

Any guesses ? I think Niki is probably Reversed because she had access to Claire's blood. Or maybe Mohinder. But I don't know who Final can be ! Wes ? Peter ? Nah, not Peter ! Maybe Monica ? Any idea ?
