Does Hiro have a third power that we don't know about? The ability to paralyze people by running and yelling at them with a sword.
He paralyzed Sylar in the Season One Finale [that was the kill point for me, Sylar had just stopped bullets in mid air, but he couldn't stop Hiro from running at him with a sword? Lame]. And apparently he has paralyzed Peter in the same way.
Even if Peter was hesitating because he knows Hiro, there are ways to knock someone out without killing them. Especially with Peter's wide array of powers at the moment.
I'm seriously thinking that their going to tease us with a fake fight. Have Hiro run at Peter at the end of the episode, then at the beginning of the episode have Hiro get sent flying. No fight at all.
I'm rather annoyed at this no fighting thing this show has. It's a show about people with powers, but there's only like two bad guys and a corrupt company. The rest are Good guys [so to speak]. People should be fighting. You can still have character development, but a smackdown was teased at and hinted at all season long last year and nothing [I mean NOTHING!] happened last year.
Just IMHO.
