Another theme is growth. Lucy might be portrayed as growing up in Narnia, learning more about the magical world and her place in it as a little sister.
A third common theme is the exploration of new magical adventures. Writers of fanfiction love to send Harry and Lucy on quests that neither of them could have had in their original stories. These adventures might involve exploring new magical lands that are a blend of Narnia and Hogwarts - like settings, or encountering strange and powerful magical creatures that are a combination of the ones from both series. This theme adds an element of excitement and novelty to the fanfictions.
Perhaps Peter's job in the bar is a way for him to gather information. He might be on a secret mission, and the bar is a place where all kinds of characters come. He has to blend in as a bartender while listening for any useful news. He could meet old Narnian friends or foes in disguise there.
The theme of redemption can also be found. Sometimes an original character has made mistakes in the past and through their interactions with Peter, they seek redemption. Additionally, the theme of family is there. Even though the original characters are new, they often become part of Peter's 'family' in Narnia, and they learn the importance of family bonds and loyalty.
