This may be a bit of a long shot, but, with the amount of easter eggs in RDR2's open world, you never know. Has anyone spotted any reference to Red Harlow, the protagonist from Red Dead Revolver? I remember him being mentioned in RDR1 at one of the campfires, but as far as I've explored so far in RDR2, there doesn't seem to be any reference to him or to the OG Red Dead game.
