If the Evil is themed to specifically oppose my character (causer vs fixer), I have an idea who (by rolename) they may be, but I see no evidence that that is the case.
Alphabetical thoughts...
EP's clones so far flipped are spoilers (getting in the way, but so far avoided being bad), not yet sure about Vishda. Depends on relationship to Hector as the other clones were to Fish as to whether EP is supposed to be Good/Neutral/Evil cloner? Run out of ckoning actions?
Fish, I'm inclined to see as innocent (no evidence of being liable to 'explode' like the clones), but as template for the clones could be ill-inclined. But that'd be a rubbish Evil. Sit around and wait for multiple copies of self to be created (especially after the first roleflips, and us now knowing exactly what to do, is that even likely?) for a win... Long, long shot.
Hector: Seems supported by Vishda. Has not caused Paradoxes, but might (especially with a copy of uncertain alliance) be playing the longer game. Has been looking a bit trigger-happy with the Elephant gun, potentially, and perhaps rightly annoyed by me and Fish. Maybe Ok, but uncertain. On balance.
Myself: Can't speculate as to my own status, as I know it, obviously, but for the sake of completeness I shall reiterate that I was resigned to not getting the associated win, if it was just a mechanics game, but if there's a bad guy then I have a purpose. Wondering if I should have held off being peacemaker/rationalist quite so vehemently, in the early stages. That may be my big error.
Vishdafish: Clone of Hector. Knows Hector's conditions. Like the other clones may have more (unrevealed) information than the original, but comes in late (and conditionally upon EP!) so not an 'original evil'. But a potential Spoiling Neutral that we could perhaps test further, may or may not help decide if originals Hector/EP (Hector always wanted to destroy EP, though I was reluctant) actually does what they appear to do....
