S13E01: The Grand Swing

Jamie deliberately disobeys Ben's order not to drive the supply wagons. During his recklessness, the wagon goes out of control on a sharp curve and is wrecked. Nobody is hurt but a badly injured horse has to be put to sleep. Fearing punishment, Jamie decides to run away, until Ben decides to take him on a tour of the Ponderosa, namely to see how others handle their mistakes in positive and negative ways.
