John (Kevin Costner) doesn't have cancer, so he is not waiting around to start getting his house back in order in Yellowstone season 2 episode 2. He leaves the hospital against doctors' recommendations (though they are sure to point out that had he previously listened to his doctors he wouldn't have ruptured the ulcer and tell him he has to do swimming as physical therapy) and is taken back to the ranch by Kayce (Luke Grimes).
