Thanks to Anon for the pic.
According to numerous tips, Michael Aiello has been caught saying, at the new employee orientations, that about 70% of the roles given out are code names due to message boards and fan sites.
My response – Ouch.
Here is my take on it – Roles we know that will return: Chainsaws…. I wouldn't say that it represents the entire 30% of the non-coded roles, but its a good portion of them. For all we know he could have been clowning around with the new employees in hopes that they wouldn't reveal their role.
