A common theme is his leadership during the Civil War. Fanfics often explore how he made difficult decisions.
Equality is another theme. Writers might expand on Lincoln's fight for the end of slavery, showing his internal thoughts and struggles. It could be about how he was influenced by the people around him to push for more radical change.
The theme of perseverance also shows up. Lincoln faced many setbacks and challenges during his life and presidency, and fanfictions can tell stories of how he overcame these difficulties, whether it was political opposition or personal tragedies.
Friendship is also a theme. Even though they are siblings, their relationship can also be seen as a form of friendship. Fanfics may show them having typical 'friend' moments like sharing secrets or having inside jokes.
One of the best stories is about Lincoln's honesty. As a young store clerk, he once overcharged a customer by a few cents. When he realized his mistake, he walked a long distance to return the money. This simple act of integrity was a sign of the great character he would later show as President, always striving to do what was right and fair for the nation.
One common theme is family. Since they are siblings, a lot of fics explore their family bond in different ways, like how they support each other during family dramas. Another theme is music, as Luna is very much into music. So, fics often have them making music together or Lincoln getting into Luna's music world. And friendship is also a theme sometimes, as their relationship can be seen as a special kind of friendship within the family.
One common theme is growth. Lincoln and Lily often grow as individuals through their relationship. Another is family support, as they rely on each other within the family dynamic.
Another common theme is adventure. They often go on different adventures together, like exploring an abandoned house or trying to find a hidden treasure in their town. These adventures strengthen their bond and make for exciting reading.
One common theme is mutual understanding. Since they have different personalities, the fics often explore how they come to understand each other better. For example, in many fics, Lincoln learns to appreciate Lucy's gothic nature.
One common theme could be friendship evolving into something more. Since they might start as friends in the original context, fanfics could explore how their relationship deepens romantically.
Romance can be a theme as well, especially in fanfics that explore a more developed relationship between them. It could be about their first crush on each other, or how they gradually realize their feelings are more than just friendship. Some fanfics might also touch on themes of self - discovery, where through their relationship, they learn more about themselves and what they want in life.
Friendship is also likely to be a theme. Even if it starts as a simple friendship in the fanfic, it can gradually transform into something deeper. The fanfic might focus on how they support each other, have fun together, and overcome obstacles as friends, which then could lead to a more complex relationship.
