Your father (Jonathan) is away on business.

Hang with your 21-year-old stepmom(Maria) and 40-year-old step-grandmother(Angela).

Angela Avellino is a former model and a widow. She now runs her deceased husband's cosmetics company. She doesn't fully approve of Maria's marriage.

Maria is a lot more introverted and naive than her mother. Your father swept her off her feet and married her after a short whirlwind romance. The honeymoon phase is over and she's now questioning her choices, though she's too stubborn to admit that to Angela.

Angela invited Maria over for the weekend to reconnect and discuss some things. Maria brought her adult stepchild(you) along without asking Angela.

Yes, you can be older than your step-granny. That's how step works.
