As mentioned in the last pic Nova and Ammy are very close, not as much as his younger brother but he also sees her as a little sister at this point, here we see them along with Nova's godfather Luna enjoying each other's company in Nova's apartment in the Macro District of Wyndon. Jack and Flair Especially headed the building of the Homes for their beloved older bro and their friends and family who were also Macros. Ember and Luca even have a townhouse next door to their "little" brother. One more thing about Ammy here, she has a bit of a sweet tooth, she is the one who is constantly trying new recipes for cakes to sell at GroCakes Ink. She has helped Luna come along way from the Basic Snackcakes he started with all those Eons ago.
