I think the point of this movie is that Violet wants a life in the outside world but she is so close with Grace she will never be able to leave her. The entrance of Luke into Violet's life begins to stir things and makes her question herself; she has this great bond with her sister but she loves Luke & he can give her the life she wants. Through the movie Grace seems to be having the flashbacks about how she always has to be the winner and she can never fail. I think it's this blind and selfish drive that destroys Violet since it is expected that Grace would be as protective of Violet as Violet is of her. I still didn't understand the physical connection they shared as well like how they can feel the other sister's pain. I also completely hate Grace for ruining the chance of a happy ending for Violet and Luke.
