‘We don’t need a family superhero. You have created a world for yourself where you have this load-bearing filial and sisterly duty, but it’s all over now, if it ever truly existed. The film is finished. You can just be Grace. Be whichever Grace you want. Disappoint us if you want. We’ll love you anyway. Yes, our parents will grow old and yes they will get sick and yes they will die, but that will happen to us two as well.
