The Village Butcher Creek (Red Dead Redemption 2)

Near lake Elysian Pool after camp a woman came up and asked to warm up by the fire, and then told me about a certain type living in the village Butcher Creek, who calls himself a demon. Found this village (not far from the lake). He walked and wandered through it, into the conversation to join no one with me does not want to. Can anyone held? What you need to do then?
