Calling one of the character, the mother, with only her title, and no real name, unlike the Tiffany sister and the Trudy aunt, is making the chat AI sometimes completely confused, lke for example making it behave as if Trudy is sometimes another daughter of the Mom. The website model of chatAI already struggles with each character of a chatbot beyond the first, so when you throw three characters as a bundle, but they are not all of them clearly defined by name and title, it is really a source of issues. Also, kudos for the picture, even if a bit blurry lowres: the three characters share a subtle family lookalike visual feel, though not being twins or clones, but realistic two mature sisters and an offspring, and the body types are rather believable and realistic.
