– In the latest “Heroes” news, the casting of young Nathan involves a storyline in which an article of clothing sparks a memory in Nathan that sends him back to when he was eleven. “Something happened to young Nathan but old Nathan doesn’t remember it. How can that be? It has to do with a character we have met before,” said Adrian Pasdar, who plays Nathan.
