Red Dead Redemption Episode 4: Let No Man Put Asunder

"John Marston encounters a strange man south of Mescalero, who seems to know a lot about John's past and claims to know him from his days running with the Van der Linde gang. However, the strange man is very coy and never reveals how he knows him. He then asks Marston to complete a couple of tasks, both of which turn out to be moral dilemmas, and the Strange Man's tone hints at what course of action he believes Marston will take in each case."
"Marston comes across an elderly man named Billy West, picking flowers on the side of the road. The man wants to give his wife, Annabel, a bouquet for their Golden wedding anniversary. He asks for Marston's help in gathering the flowers."
"Marston notices a campsite out on the trail and decides to ask the occupant for a short rest from his travels. He meets a man named Andrew McAllister, who welcomes Marston to his camp. After a small conversation, McAllister tells Marston about how he is searching for a rich source of water for drilling."
"Outside Coot's Chapel, Marston meets an old woman named Alma Horlick whose soon-to-be husband, Peter Turner, has disappeared on her wedding day, which apparently seems to be the same day Marston is talking to Ms. Horlick, according to her."
