Because she pities her(the vile lady). In her words, although she apologizes she emphasized the things and accusations casted on her even though she's innocent. So it's kinda like sarcasm to apologize when in turn FL really was just calling her out. Playing with words, if I do say so myself.
I'm a bit unsatisfied... Why is the FL feeling a bit sorry for that bitch... She deserves every ounce of misery and they should punish her more
