Red Dead Redemption Episode 12: We Shall Be Together in Paradise

"At Brittlebrush Trawl, Irish helps John get across the river to Mexico. On the way, they get attacked by quite a few of Irish's so-called friends."
"John Marston walks into Chuparosa, a dusty & quiet town, fresh off the ferry and a new arrival to Mexico. He is greeted in a rather unpleasant way by a group of banditos and they demand a toll. They continue to terrorize John but he is forced to gun them down and leaves them to rot in the sun in the middle of the town after one steals his hat and another tries to make him take off his boots. However, an old man witnessed all of this and mocks John's gun skills. He is an American too and offers to show John some techniques. The pair bond as they practice shooting. The old man is revealed to be Landon Ricketts, a retired and legendary gunslinger who was supposedly the fastest shot in the Old West. He gives John a lay of the land, talking about the local government and the smell of a revolution coming."
