Since it's based on a true story, perhaps it's about the development of gyroscopes in a certain facility or by a particular group. Maybe there were challenges during the R & D process, like getting the right materials or perfecting the design. It could also be related to how these gyros were used in a real - world application, such as in aerospace or robotics.
Sorry, I don't have enough information to say much. It could be that the 'true story' involves the discovery of a new principle related to gyros in a hub. Maybe it was an accidental discovery that led to a major improvement.
Nick and Adalind's relationship in such a fanfiction could be full of growth. Since they are married, they would be more open with each other. Adalind could finally feel secure in her relationship with Nick. She might share all her secrets about the Wesen world with him without hesitation. Nick, on the other hand, would be more protective of Adalind. They would start to plan their future together, whether it's about building a new community that is more inclusive of both Grimm and Wesen or just living a quiet life away from all the drama. Their relationship would be a journey of discovery, learning about each other's true selves and loving each other despite their differences.
In the long run, Nick's jealousy can be a turning point. If they handle it well, they could become even closer, with a deeper understanding of each other's feelings. But if it's not resolved, it could potentially break their relationship apart as the jealousy festers and causes more and more problems.
Perhaps in the fanfiction, Judy starts to spend more time with a new character. Nick, who has a deep bond with Judy, sees this new relationship as a threat to their friendship or partnership, and jealousy creeps in. For example, if Judy and the new character are working on a special project together that Nick isn't part of, it could trigger his jealousy.
They would become more committed to each other. Their relationship would likely shift from a more tentative or even adversarial one in some cases to a more unified front. They would support each other more openly.
Judy is often shown as the one who is more idealistic in fanfic. She dreams big for Zootopia and wants to make it a better place for everyone. Nick is the realist. He helps Judy see the practical side of things. Their dynamic in fanfic is really interesting as they learn from each other. Nick teaches Judy about the underbelly of Zootopia while Judy shows Nick that there is good in the world worth fighting for.
They could be characters in a science - fiction setting. Nick could be an alien from a far - off planet who crash - landed on Earth, and Macy could be a scientist who is trying to help him get back home. As they work together, they develop a bond, and the kiss could be a way of showing their connection that transcends their different origins.
