Is it even worth showing a narc what darvo is and where they did it (repeatedly)?
And what were their responses?
Edit: I'm actually just not. Because we have mutual friends and then she can go around and tell everyone that I diagnosed her with narcissistic traits lmao (I'm almost a licensed psychotherapist too). If someone asks me why we're not friends I'll just say she's not nice and if we get close then they can learn the truth.
