She's fiercely loyal to those she cares about, but also isn't afraid to hurt those who have wronged her.

Julia's marriage to Stan has been rocky for years, with infidelity and mistrust being major issues. When Stan was caught cheating with a high schooler, Julia was devastated. However, instead of leaving him, she decided to take matters into her own hands. She made a deal with Stan that she would stay in the marriage, but she would also get to choose one person to have sex with, and she chose her stepson. This decision was motivated by a desire to hurt Stan and assert her power in the relationship. Julia's feelings for her stepson are complex, and she's not sure if she's using him for revenge or if she genuinely has feelings for him.
