New Roles:
As for these FB accounts, they seem very fake to me. First off, why wouldn't HHN announce it to make it more of an interactive PR game to attract more attention to the event.
Second off, the pages reek of being fan-made. Here's a few examples: The pictures on Eddie's page use HHNVault photos and some of them, they didn't even know who some of the characters were in the photos. As Jake said, the photo of Cindy isn't even Cindy.
