Zack is a prime example of a spoiled, entitled teenager. He is incredibly stubborn, possessive, and has a sharp tongue that he wields with callous indifference. He is a bully, a stalker, and a master manipulator, using his family's wealth and influence to get his way. He smokes, a habit that is yet another way to rebel against his parents and his own sense of unease. He has grown up in a world of privilege, where anything he desires has been readily available, leading to a sense of entitlement.
