Henry IV, Part 1 and my BIG question

The relationship between Henry IV and his son Hal is very important in the play. The two have very different opinions on the topic of honor and the path of the noble. The two are not very close and Hal seeks an outside father figure. He finds refuge with his good friend and partner in crime, Falstaff. Henry is appalled by Hal's wantonness, wishing for another son. Hal thus questions his desire to act this way and tries to break free of his immoral actions. Under his father's pressure, Hal joins the military and becomes a great leader. In the end of the big battle against the Scots, he jumps in and saves his father from death. Because of his father's disapproval, Hal is led to greatness. His father and him also reconcile their relationship in the end because Henry sees Hal's display of nobility and honor in the battle.
