Events of Red Dead Redemption 2
Some time after Arthur interacted with and, optionally, robbed Mama Watson, Ethan and his brothers visit their mother to tell her about trying to use the money they get from their criminal exploits to move her out of the country. She will express disinterest in the plan.
If Arthur attempts to enter the house, the brothers will attack him, and he has the option of killing them all, subduing them, or simply running away.
Ethan appears as a bulky man. He has swept back ginger hair as well as a well-groomed mustache and is likely in his mid 30s. Watson wears a striped blue and white shirt, dark blue suspenders and worn gray trousers, slightly covered up by his brown boots. He also wears a brown belt with a single holster.
