John Walton Sr. is a true Papa Wolf, you don't mess with his family or friends. Heck! you don't even want to mess with anybody around him! He is awesome.
There was John-Boy who ran away from home to find a job in a city in the first season episode, "The Deed," to help his family who was fighting in court to keep their land from being bought and clear cut by a company. That intention was initially shattered when John-Boy was robbed of his pay, but with the help of a newfound friend, he managed to stay in the city and got to catch the robbers in the act and got a cash reward big enough for him to return home and pay the legal bills.
