OK, I just checked and we are two episodes behind here in the UK. (Though I don't mind reading spoilers, as a few of you may know
)
Anyway, isn't this season, or half a season called Villains? I'm thinking that along with the regular Villains, the good guys are also showing a bit (Or a lot ) of their darker selves.
I love that Hiro has no evil to show, he is "pure" hero.
OK, this all might be a bunch of silliness, I'm just thinking out loud.
