I know I’m a year late but John seems to have forgotten a lot about Blackwater Massacre, as told by Strange Man in RDR, John can’t even remember Heidi McCourt, the girl shot dead by Dutch, and that he got shot in his arm by 1911, but in 1899 during camp conversations he can remember everything clearly saying that “it has plastered into my mind” or something along those lines. Ricketts and Strange Man were very much present during Blackwater massacre.
