Hey there...
I've only watched the first 10 episodes but I had this thought and I just want to put it out there.
Having seen how Charlie Andrews and Hiro Nakamura fell in love in episode 10 and breaking my heart to hear that she was dying anyway (I have a soft spot for romance) I had this little theory that keeps alive the hope of them getting back together.
Slyar, in episode ten, seen to understand the workings of humans, especially the brain. My first thought was why does he turn evil immediately instead of recognizing the positive effect his power could have.
Maybe by the end of the show Sylar will have turned good, and Hiro could teleport Sylar and himself back to before Charlie dies, and Sylar can cure Charlie of her illness/blood clot.
I just hate the idea that they could leave their romance dead in the water like it currently seems.
Any thoughts.
BTW: This site is f***ing amazing! Excellent job by everyone involved.
