Nah, I believe she already gave up. Her misconception about Ruby and her brother relationship was cleared up,. Not only she was wrong about they being lovers, but found out all the abuse Ruby gone through.
i read some spoilers that she became a nun to repent and her brother died of poison (the slow kind). idk when. and there are exactly only 3 people who knows about freya's poison incident. it was only ruby, freya and freya's uncle.
Actually according to the novel,Freya still have some trick in her,,but eventually she gave up and became a nun in another country as izek place her there for not killing her in return
She did according to novel,,I won't spoil it but yeah
i have gut feeling about that Freya bitch will do something to ruin and be in this couple's way to give them another hard time, especially to Ruby.
