Have you been following back story comics of Heroes? I have before; I kinda stopped for now.
Michael McCallister was involved in the production of the comic. (At least that's what I understand.). Ray got a signed copy of the graphic novel at Comic Con. Pretty cool.
I need to get back reading the back stories at NBC.com. There are a lot of interesting characters and a lot of stuff explained, like Petrelli and Linderman first meeting.
