S3, E1: The first chapter of "Volume 3: Villains" kicks off moments after shots rang out, as the shocking identity of Nathan’s (Adrian Pasdar) assassin and the reasons why the Texas press conference had to be cut short are revealed -- immediately throwing Peter (Milo Ventimiglia) and Matt (Greg Grunberg) into unexpected, uncharted territory. With his powers partially restored, Sylar (Zachary Quinto) decides a visit to Claire (Hayden Panettiere) could give him a boost. Meanwhile, in Tokyo, Hiro (Masi Oka) and Ando (James Kyson Lee) are charged with safeguarding a family secret that could split the planet apart, and discover that the path to a grim future starts with shady speedster, Daphne (guest star Brea Grant). In New York City, thanks to Maya (Dania Ramirez), Suresh (Sendhil Ramamurthy) makes a startling breakthrough that could change the world -- or just destroy his. And who is Tracy Strauss? Ali Larter, Cristine Rose and Jack Coleman star. Noah Gray-Cabey, Ashley Crow, Randall Bentley, Jimmy Jean-Louis, George Takei, Malcolm McDowell, Carlon Jeffery, Jamie Hector, Bruce Boxleitner, Francis Capra and Blake Shields guest star.
