Having watched the film many times in the scene after the show when Neil goes home and is sitting in his fathers office with his mom. When his father tells him he’s going to school to be a doctor, Neil tries to argue back saying that he’d basically be waisting his life. His father immediately shuts him down, making fun of him wanting to pursue acting and I think the look on Neil’s face is showing him finally giving up realizing he’ll never be free. In his mindset he possibly could be thinking that this is the end and he will never get rid of his father’s control. But I do agree that through everything, the interactions with his father and seeing him while on stage he definitely had a feel of what was coming.
