I'm don't know what kind of things Jamie excludes from the night scenes, but it's possible that Kirino is a cult leader who was roleblocked or something along those lines. And maybe the CL targeted somebody who is immune on night 1 or 2, and the target therefore didn't get recruited. Or something like that, idk.
Although, I can't really think of any characters in the franchise that would really fit as a cult leader. Unless there are bosses in the game, which I doubt. I think, at this point, it is actually safe to assume there is no cult in this game. More likely, the second third party role is simply a survivor or a lyncher or something. There are actually quite a few characters who could be good candidates to be a lyncher (Ganondorf, Bowser, etc.), whereas I currently can't think of a character that might be a survivor.
I know this post is really confusing and poorly written, but I've had a long day and I'm reeaaally tired. I'll post more substance later.
