I remember a post by Tess that talked about changing the narrative for Juliette, but I didn't see the continuation you quoted there... So if it
really was Tess who wrote that, then anything is possible.. And then such a "harem"
(where the sisters don't touch each other) might make sense.
But then it should also mean that "pure" EvilDom Kane (and not a "demon" at that) probably won't have any more evil content with Juliette at all (like the scene on the yacht where no demon flag is needed).
I can't say I'll be sad in this case...Yeah, I like Jules herself (and in pt2 I think she became even prettier), but I definitely don't like the murders in some of her scenes...And that's why the option with evil Dominica and "new Jules" is totally fine with me. And if it will be realized what Tess voiced on behalf of her character (concerning Jules), I will be the most satisfied as a March cat eaten sour cream.
