Regarding the Facebook pages... first of all, Cindy's picture is shopped, Jacks can easily be found on google :Here, and Eddie's is clearly from HHNVault. This leads me to believe two things:
1- These are without a doubt fake's created by a Horror Night fan
or
2- Uni wants us to think these are created by a fan, but actually have legit info. That way we don't rely on them to much, but still tease us... Just a conspiracy thought
