Personally I tend to disregard anything that happens in the graphic novel. The stories never seem to be all that important to the main story, and some of the things that happen in them are ridiculous even by Heroes standards.
For instance: I can suspend my disbelief enough to accept that someone could communicate with a machine using their mind. After all the brain is like a biological computer running on electrical impulses. However in the Graphic novel Hana's consciousness was saved, even though her body died, by uploading into cyber-space.
In my opinion that's too much of a stretch. Evolved humans being able to do amazing things due to genetic mutations is one thing, but her body was gone. And there is no computer advanced enough to hold a copy of a human mind. Personally I don't think that all of the computers in the world combined could do it.
That story line was what made the graphic novel jump the shark for me. I've tried to read a couple since, but I just can't get in to them....

And besides, it seems to me that one of the main reasons they write the graphic novel is to peddle Nissans.
Of course they've been doing that on the show since season one as well....
