After like 300 years of living with each other lup and taako have developed like a language of food. Lup knows when taako is pissed and needs to rant about something because he made brownies, taako knows the difference between lup being existentially sad and lup being dead book character sad based on whether or not she puts walnuts in her muffins.
One day lup came into the kind of living space and was like hey guys i made cinnamon rolls, and taako was like cinnamon rolls? Because cinnamon rolls is what lup makes when she gets crushes. But instead of saying anything he makes quiche for dinner that night, which lup knows means “lup i know your fuckin secret spill it”. So the next day she made peanut butter cookies which she knows taako can’t eat which pretty explicitely means “fuck off taako” and they didn’t talk for a week straight
