Fan Theories

• Ando's powers will manifest at the beginning of this episode.
• Peter will kill Nathan.
• More than one character will die in this episode.
  • Only to come back again either later this season or next season.
    • Meredith, Flint, Daphne, and Nathan will die. For good, too.
      • Unlikely as Adrian Pasdar and Brea Grant have filmed episodes in Volume 4.
        • I have not heard anything about Adrian filming for Volume Four. Brea could've been filming a flashback or even a vision a la D.L. and Linderman, who is haunting or helping Matt. She can die and still remain on the show.
• This episode will show the battle between good and evil according to the promos.
  • In continuance of the above theory, the looming battle between the Company (Angela's team) and the Pinehearst Company (Arthur's team).
• Echo will return to Primatech Research for revenge and face-off with Sylar's sound manipulation, destroying the facility in the process.
  • The above fact sounds unlikely as Sylar is against Primatech too in the current season.
• The title refers to a global war involving thousands of genetically-mutated humans after Mohinder's imperfect formula is leaked and mass-marketed to the world, creating a side-effect in every manifestation.
• The title refers to the ability of all humans to do good and/or evil. There is a hero and a villain in all of us, even Sylar, Peter and Arthur.
• Kaito's ability will be officially revealed in this episode.
  • As well as Ishi Nakamura's, judging by some photos
• Daphne will be killed, setting Matt onto a darker path.
• Hiro will regain his memory this episode.
  • Many main and minor characters will be put in a terrible situation together -- like an explosion or a shootout -- which will be the cliffhanger for the end of the season, leaving us to figure out who lives and who dies.
