I think Mason says it best—and I believe this with everything in me—he says it about his relationship with Grace but I think it pertains to any relationship, when he says: That’s what this is about. We talk about it so I can hold your hand and walk through shit with you. I think that’s what love is. It has a lot to do with feeling and emotion, but it’s a mixture of that and, I am here with you, like through the shittiest times when you’re psychotic and crazy, I’m still going to be there until we get through the other side. That’s the theme of most relationships in the movie.
