Red Dead Redemption

Looked around and some are saying when John showed up to Micahs hide out he realized that John wasn't the snitch. And that Arthur was right. His two "sons" were forever by his side and gave him everything they had even till the very end. John showing up meant someone was still running their mouth for them to know where they were hiding. also, by this point Dutch had lost his mind after falling on his head multiple times throughout the game.
