Another theme could be the passing on of values. Harry and Ginny would want to instill in their kids the values they hold dear, like courage and loyalty. This can be shown through various interactions and situations in the fanfiction.
The exploration of new magical abilities or knowledge is also a theme. Since it's set in the future, the kids may have access to new spells or magical techniques. Harry and Ginny would be both amazed and proud as they learn about these new things from their children.
It's possible that when they meet their kids, they realize that their family has a special destiny in the wizarding world. Their kids could be the key to uniting different magical communities or solving an ancient mystery. This could lead to a series of adventures where Harry and Ginny, along with their kids, embark on a journey to fulfill this destiny.
One common theme is the kids dealing with the legacy of their parents. Since Harry and Ginny are so well - known in the wizarding world, their kids often have to live up to that reputation. Another theme is friendship. Just like Harry, Ron and Hermione, their kids form strong bonds with their peers at Hogwarts.
A theme that is often explored is the idea of legacy. The Potter family has a great legacy, and Ginny's interaction with them can bring out how she fits into that magical world's history and future. Also, love and romance can be a part of it, as relationships might develop between Ginny and some of the Potter family members or their friends.
Well, one possibility could be that the kids from the future come back to prevent a great disaster in the present. Maybe a dark wizard that was defeated in their time has somehow found a way to be reborn in the past (the present in the story), and they need to stop it before it's too late.
Love is a very common theme. Most of these fanfictions focus on the deep and abiding love between Harry and Ginny. Another theme is adventure. Since they are from the wizarding world, they often go on adventures together, which are exciting to read about.
One theme could be family. Harry finally gets to have a proper conversation with his parents, and Ginny becomes part of this family moment. It's about the connection between different generations and how family bonds can transcend time. For example, Harry could learn more about his family's history directly from his parents, which would strengthen his sense of identity within the family.
Family is also a big theme. They come from different family backgrounds, and in fanfiction, how they blend their families or start their own is often written about. For example, how Ginny's large family interacts with Harry, who has no real family of his own at first. And there's also the theme of friendship, as they have friends who play important roles in their lives even as they are in a relationship.
They are likely to meet their future selves. This could be a very strange and enlightening encounter for both of them. They might also meet their descendants, like their children and grandchildren, which would be a heartwarming experience.
One common theme is power. In a dark Harry scenario, his power might be more uncontrolled or misused, and Ginny could be either a stabilizer or a catalyst in that. Another theme is secrecy. They might keep parts of their relationship or Harry's true nature a secret from others.
One common theme is miscommunication. Often, they fight because they haven't fully expressed their feelings or intentions to each other.
