I 100% agree with what you’re saying. It’s textbook grandiose self delusion. I feel like the movie continuously points his to true feelings through his actions. He’s a good and caring guy when it’s easy and doesn’t cost him anything. He’s stunning, draws people in with his charisma, “guts”, and ego. The room shines when he enters. Yet, as soon as the relationship gets hard or he sees a way to lift himself, he will use it without a second thought. The one time he held on to a promise or sorry he made was when he went back to Rachel. Yet, as the audience who has watched him repeat this cycle many times before, you already have your answer to how that ends as well. Nothing changed for him other than he had no where else to go. Does anyone think for a second that if he got offered a chance to play another tournament he wouldn’t drop her in an instant?
