The category is clear, if a character doesn't act in a way in the description then it will be removed from the page.
As for "speculative" I have removed it from pages before where other characters guess a character is that way, but the character themselves doesn't act that way. Its all about the villainess' reaction and will be judged on that alone
re the "talking about" criteria though, couldn't a villainess lie?
looks at URL* hm...
how feasible would it be to absorb w:c:Villainess and take over it's URL? A tad shorter. Someone made that Aug 2016 and it merely has 339 pages, your wiki made July 2014 now with 7000+ articles definitely is the more prominent.
