Vernon is a rebel and a close associate of Worcester. He often tries to be a voice of reason when Hotspur gets carried away. Vernon is perhaps best known for deceiving Hotspur. When King Henry offers to call a truce, Vernon and Worcester keep the information quiet for fear that Henry would eventually go back on his word. (They're probably right.) At the battle at Shrewsbury, Vernon's captured by the king's forces and sentenced to death.
