Q1: Does your character(s) like to cook, bake, etc.? Are they good at it, and if not, do they want to learn? What are their favorite things to make?
Yes, Melody likes to cook sometimes. She used to work in her family's restaurant ran by her mother, Lynn. I'm not sure what she would like to make, but I'd assume pretty simple foods like burgers, donuts, fries, etc. She likes donuts.
Q2: Does your character have any pets at home? If so, tell me about them! If not, what would your character have as a pet? What would they name it?
No, if she would have a pet she would likely have a fox, probably naming it something fancy like "Solenne."
Q3: Do your characters have any fond old memories from their youth, before they started working for NT? Back on their home planet, etc.
Yes, she misses being a carefree child. For Halloween (or whatever is the equivalent on her home planet) she would always dress up as a wizard or witch, mostly wizard. Nowadays, dressing up is a way to cope for her.
