Nina Simone - Ne Me Quitte Pas (with lyrics) -- mixed with The Godfather theme is Noah's theme (it's the culmination of a teen's misunderstanding of relationships and love and being left alone/people leaving her and this dangerous thing that comes to the surface and hurts the people around her)
Noah in her desert oasis home. The hitchhiker calls her "The Girl with No Name" (after Clint as "Blondie, the Man with No Name") at one point because he realizes he doesn't know her name yet. Or she won't tell him. We all realize we don't know her name.
