In this fanfiction, Harry would grow in his ability to work with others in a more equal way. He has often been the 'chosen one' but in this rescue of Luna, he would learn to rely on Hermione's intelligence and Luna's creativity just as much as his own skills. Hermione would develop a more open - minded approach. She would start to see the value in Luna's unorthodox ideas and incorporate them into her own problem - solving. Luna would see herself as an important part of the trio. This would change her self - perception, and she would be more likely to step forward and offer her help and ideas in future adventures with Harry and Hermione.
For Harry, this would be another chance to prove his heroism and loyalty. He would become more confident in his leadership abilities as he takes charge of the rescue mission. Hermione would grow in her ability to trust her instincts more. Usually so reliant on books and knowledge, she would learn to rely on her gut feelings when it comes to saving Luna. Luna, on the other hand, would become more aware of her own value. After being saved by her friends, she would realize how important she is to them and become more assertive in her own abilities.
In the fanfiction, Luna might be lost in a time - loop created by a malfunctioning time - turner. Hermione realizes what has happened due to her familiarity with time - turner magic. Harry goes with her to enter the time - loop. Inside, they face various challenges from different time periods. They find Luna, who has been trying to break the loop on her own. The three of them then work together. Hermione figures out the correct sequence of spells, Harry provides the necessary distraction to the time - loop's guardians, and Luna uses her natural connection to magic to help Hermione complete the spell that breaks the loop.

Another way it could develop is that it could create a rift among their friends. Some friends might support their relationship, while others, like those who have always shipped different pairings, could be against it. This could lead to some interesting plot twists and drama within the fanfiction story.
