 He's going to kill him. So he takes his wheat threshing bat and he swings it and knocks the brother off the horse and continues to beat him until he's dead, shoves him under a pile of wheat, takes his clothes, takes his horse and rides north. Now he is in the middle of enemy territory. He is so far from any allies. He is very easily identified as a slave. He has a thick metal band around his neck. He's a white man. So he rides for 16 days straight.
