Here are two ideas if I can interest you for the next chapters. One where Linka embarrasses her older brothers with their respective crushes, for example Loki Beatrix, Luke and Samuel, or Lane and Penny, the female version of Benny. Obviously she doesn't do it with malice but with a bit of almost maternal affection and a pinch of naivety, for example by showing them photos of when the boys were little. According to Linka she babysits some little girls in the neighborhood, but Levi accidentally shrinks Loki, Luke and Lynn and these little girls find them and play with them like they were dolls, like with princess dresses, makeup and diapers. I think it would be hilarious and sweet.
