Okay, this is the first time I have ever posted anything online so please bear with me.

My theory is that Hiro goes back in the past and becomes Kensei (sp?). The stories that his father told him about Kensei were really about Hiro. Hiro gets together with the swordsmith's daughter and is really his fathers great great great great great great great great great great great great Grandfather. He is his own descendant from 435 years earlier.

It's crazy but it could happen.

I'm not so sure about the theory you presented, although that would be unusual. However, I did note something in tonight's episode that may tell us a little about Hiro's history.

I don't know if anyone else picked up on it, but Mama Petrelli stated that she was not in a relationship with Kaito. She said, "not for a long time now." or something to that effect. Which means that she WAS involved with Kaito in the past, a long time ago. So, I believe that Mama Petrelli may actually be Hiro's Mama also. As usual, I'm certain I COULD be wrong, but her statement does leave one to wonder. I also thought I read a spoiler from either Eonline or TV guide that said there was going to be a connection between Hiro and the Petrelli clan.

i dont think he's goin to "get" with her. i think hes just ganna set up kensei with her
