Peter's been having premonitions coming to him in dreams since the first episode. Perhaps that's a latent power of his as well? That said, the dreams he's had have been somewhat misleading so far. However, if you take them at face value, it becomes an interesting question:
Maybe by some freak accident, Peter gains the radiation guy's power and blows hisself up in the future... But then again future-Hiro knew him and commented about "looking different without his scar". And I'm assuming future-Hiro came from a timeline with the explosion occurring.
In any case, AWESOME PAINTING OF HIRO & DINO WITH SWORD!!! can't wait for that ep!
Also, lol @ Peter/Officer Parkman feedback loop of mind reading.
