I still wonder if Cooper genuinely cares about Cyrus or he just sees him as an item that would bring him a lot of money when he sells it
I mean, when they're in the train, Cyrus is being nervous and anxious that this is the last day when he sees Cooper, while Cooper is just sitting and happily searching for the lodestar's price. I think that already shows that he only cares about money and nothing about Cyrus personally
