Often, there could be themes of self - discovery. Harry might learn more about himself through his interactions with his dad in these fanfictions. Also, themes of acceptance, both of each other and of the situation they are in, can be quite common. The 'lemon' aspect might add an element of sensuality, which could be related to themes of love and attraction within the family context in a fictional and often very different take from the norm.
Often, there are themes of love and sacrifice. Harry's mother sacrificed herself for him in the original story, and in fanfiction, this could be further explored in different ways. It might also touch on the theme of regret, perhaps on Harry's part for not having known his mother more. Additionally, some fanfictions might include themes of magic inheritance, with his mother passing on certain magical abilities or knowledge to Harry in unique ways.
One common theme could be family dynamics. Since it involves Harry and his brother, exploring their relationship, whether it's full of love, rivalry, or a mix of both, is often seen. Another theme might be growth, like how they both develop as characters throughout the story.
The theme of friendship can also be incorporated. Maybe Lemon makes some special friends during her adventures with Harry, and these friendships play an important role in her development. It could be that she meets other young wizards or magical creatures, and together they create memories and learn valuable lessons about loyalty and kindness.
Often, there is a theme of discovery. Maybe they discover new magical abilities together or find out something about their family history that was previously unknown. Also, the theme of protection might be present. Harry might feel a strong need to protect his twin sister, or vice versa, especially in a dangerous magical world full of dark forces.
Well, often there's the theme of adaptation. Given that Lemon is not part of the original story, the fanfiction might focus on how she adapts to the wizarding world. Family secrets could also be a theme. Maybe there are secrets about their family that they uncover together. And of course, there's the theme of growth. Both Harry and Lemon could grow as characters through their experiences, whether it's dealing with the challenges of Hogwarts or facing the dark forces in the wizarding world. There may also be themes related to love and acceptance within the family unit.
The theme of legacy is often present. Harry Potter is a famous wizard, and as a new dad, he has to think about the legacy he's leaving for his children. Will they follow in his footsteps? How will they be different? Another common theme is the support system. His friends from Hogwarts often play a role in helping him with fatherhood. They might offer advice on how to deal with a crying baby or how to handle a child's first year at Hogwarts. And of course, the theme of love. Harry's love for his family is what drives many of the plotlines in these fanfictions.
One common theme is acceptance. The oc often has to deal with the fact that their father is a werewolf and the prejudice that comes with it. They also have to accept themselves in relation to their father's condition.
One common theme is redemption. Snape, who had a complex and often dark past in the original series, gets a chance to redeem himself through his fatherly actions. Another theme is the exploration of family. It shows that family doesn't always have to be blood - related, as Snape forms strong bonds with the characters he takes under his wing.
Growth is also a major theme. Through the experience of becoming a father at a young age, these characters grow in ways they never expected. They become more mature, learn about sacrifice, and their understanding of love deepens. Their relationships with others, like their friends and romantic interests, also change as they adapt to their new role as a father.
