That's normal after being freed from mental and physical captivity. She's happy to be back home with her parents and siblings. Do you expect her to be sad?
That slime bucket who allowed her to suffer so, allowed that family to suffer so, and attempted to strip her of her indentity so as to fit this little piece of innocent flesh into his filthy dreams needs to be hurt. And so does his filthy wife-the grown-up one.
He may have ruined her chances for full happiness-left her with memories so hellish that she will never be free from them.
