With the end of Heroes, the writers strike meant they had to change things - this was not what was supposed to happen, which is why it's a bit crap.
Ahhh. From wikipedia:
The second season of Heroes premiered on September 24, 2007,[4] but only 11 of 24 episodes have been broadcast,[5] due to the writers strike.[6][7] The dispute also led to the postponement of a six episode spin-off, Heroes: Origins,[8] which was originally expected to air in April and May of 2008.[9][10] Tim Kring stated in an interview with The Post Show on G4, that Season 2 was actually supposed to encompass 3 volumes; Volume 2 (11 episodes), Volume 3 (7 episodes) and Volume 4 (6 episodes). This plan changed due to the Writer's Strike.
