Absolutely awesome. Hiro and Ando travel 5 years into the future, where they find Future Hiro. Nathon has become president, Sylar has obtained a new power, and Claire does her best to have a normal life.
Peter was actually the one to explode, not Sylar. Peter has improved on his fighting skills, and so has Sylar. The ending was dramatic, while Nathon made his speech, Future Peter helped Ando and Hiro escape the future, back to the present.
I really wanted to see Peter fight Sylar, But I'll just have to wait a little longer. This was probably one of the best episodes of Heroes, great ending with plenty of action.
