just re-watching the show, is it just me but when hiro stops time to save the little girl from the bus, after he does this he and his brother are celebrating, but right before the commercial his brother has this look on his face as if he sees something, something not on camera... anyone notice this?

First, they're not brothers, their character names are Hiro Nakamura & Ando Masahashi. Second, I think Ando was just shocked that Hiro wasn't crazy and basically just predicted the future ... wouldn't you be quite shocked.

yes thats true, thanks for setting the brother thing straight, sure hes shocked but re-watching it, he sees something, but you could be right, It could be nothing...

I think he was just shocked. If he had seen something, they wouldn't have just ignored it. They would've shown what he had seen.
