Final answer:
Jack leverages emotional appeals, takes advantage of moments of vulnerability, and proposes enticing benefits to sway group allegiances in his favor.
Step-by-step explanation:
Jack convinces the rest of the group to change allegiances by manipulating the situation to his advantage.
This can be done through various tactics like appealing to emotions, taking advantage of a crisis or vulnerable moment, and offering solutions or benefits to those who follow him.
For example, in a scenario where a character is feeling misery and has no option to change their behavior, Jack could offer a sense of belonging or propose a strategy to overcome a common adversary, aligning with the character's need for change in beliefs or attitudes.
Similarly, a character like Jack might leverage a moment of shock or vulnerability, as seen when Alec reveals that he quit his job, to sway opinions and strengthen his influence.
The notion of escape from an intolerable or humiliating situation can also be a powerful driving force that Jack could exploit to win over the group.
