The joke is so Stephen Burke isn't really greedy. He does lick ass to land business, but he also donates money. Furthermore, the conversation because of the Chad attack on the MC shows us so Stephen is actually calm and level-headed. Stephen is not a hardliner.
I think rather, so that your son, the grandfather of the MC is. In terms of age, it could fit. Lynette would be about 40 years old, her father could be about 60 years old, and then Agnes could make it 80 years old. What we know about Lynette's father is that he is also greedy and stingy. He also does not want to support his grandson, as we learned from Neil. I would not be surprised if such a person would also put his own mother in a nursing home.
Agnes said something:
MC: "I’m here to entertain you."
Agnes: "Like a monkey."
Who makes a monkey face while taking a picture? Lynette. Did Lynette always make her grandma Agnes laugh with a monkey face and entertain her with it. Now it's the MC's turn to make his great grandma laugh and entertain her.
The inheritance thing could be true, except with the difference so that Agnes disinherits her son, Lynette's father, and leaves everything to her great-grandson, the MC. Karma for Lynette's father. What he did to the MC, he now gets done to him.
