I do suspect the first timeline/real Beabitch of fooling the duke into "loving" her. I think their love isn't that much of a true love. And then, Wyknight, or what so ever his name spells like, not so long ago found out and left her. Maybe, she's the only one who fell in love at first sight?(⌒▽⌒)
I’ve been saying old Bea was in Beatrice body right now for the last two updates lololol
