Thank you, the hatred mechanics are still very rough but I think they are going to be pretty great in the future. If you dont save the fish, pick up the deerhunter X gun, king of hatred card and call Arthur "a legend" or a "very misunderstood man" in the scene with the Barley Butcherer newspaper young Sarah and Billy leaves you and Arthur joins you instead, setting up the "dark run" of the game for the future. Deerhunter X SUPPOSEDLY scales with your hatred value so when everything works as it should you will be able to use things like butchering and behaving like an asshole to max your hatestat and damage-output.
And yeah, adult Sarahs college experience will be wild, lets just say that she takes no shit from people.
