....Might as well get some of this out here in the open while we can. Some of it we all know already, some of it... I dunno if everyone knows yet.

Ash is aware of all the roles, because he got it off the Sheriff's computer. I'm not sure how much about them he knows, but he knew about this from that point—Sara told me that.

And this game's held once a year for the Sheriff's weird, alien bloodthirtsy bosses to feast on, since it sates them, or whatever.

[just in case everyone's not all up that information.]
