In PT Anderson's Magnolia, we learn that Claudia is most likely the victim of sex abuse. She is filled with self-loathing throughout the movie.
In the end scene, we see her as we did towards the beginning - in bed - but now all in white, and smiling at last. A man is standing in frame. It's not possible to see his head. Hearing him say the name 'Claudia' is barely audible.
I don't think is her father. The character standing looked too lean (and is moving too deftly). The same is true for Reilly's cop character.
Can anyone say definitively who she is talking to in the end scene?
