 The episode's main storylines revolve around Peter Petrelli (Milo Ventimiglia) and Hiro Nakamura's (Masi Oka) quest to stop the release of the Shanti virus, and Sylar's (Zachary Quinto) attempt to regain his powers. The end of the episode features a brief prologue of the third volume, "Villains", which features Sylar regaining his powers. Originally, the virus was going to be released, and Tim Kring said that it was to play a big role in Volume 3. Kring stated that the ending had to be rewritten because they did not know when the show would return to air, and they wanted to make sure that they tied up all the loose ends. "Powerless" was watched by eleven million Americans and received mainly positive reviews from critics, with many saying that it was a positive end to a lackluster season.
