Well, it could be interesting to see a plot where Harry and Ginny are having twins or more. The added complexity of multiple births in the wizarding world would bring in new challenges and joys. There could be a sub - plot about how they name the children, taking into account the important people in their lives and the wizarding traditions.
A great plot might be about the magical elements involved in the birth. Since they are in the wizarding world, perhaps there are special spells or potions that help with the process. Ginny could be using her natural magical abilities in an unexpected way during labor. And Harry could be worried about protecting his family from any potential dark forces even during this joyous time.
One idea could be that Harry discovers he has a magical ability that allows him to give birth to kittens as a form of new magic. The kittens could have special powers and Harry has to protect them from those who want to use the kittens for evil.
One interesting idea could be a special magical connection between Harry and Ginny that was formed at their births. Maybe it gives them an instinctive understanding of each other. For example, they can sense each other's emotions even from a distance. Another idea might be that this birth bond is related to some ancient magic prophecy. It could be that their union is fated not just because of their love but also due to this special bond that has been there since their very first day.
One idea could be exploring Quinn's emotional journey during the birth. Maybe she has flashbacks of her time in the Glee club and how her friends' support is helping her through the pain. Another could be focusing on the father's reaction, if he's present, and how that dynamic plays out. Or perhaps Quinn could be giving birth during a big event in the Glee universe, like a concert, adding an extra layer of drama.
One plot idea could be Twilight preparing for the birth while her friends in Ponyville are rallying around to support her. They could be gathering supplies, making a comfortable place for her, and sharing their own experiences of new life in Ponyville. Another could be Twilight having premonitions or magical signs related to the birth that add an element of mystery.
A possible plot is that there's a mysterious illness spreading among the Quidditch players, and Harry and Ginny have to figure out what's causing it and how to stop it before the big Quidditch tournament. Or perhaps a new and dangerous Quidditch move is introduced by a visiting team, and Harry and Ginny must learn it quickly to stay competitive. They could also have a friendly rivalry with another couple who are also big Quidditch fans.
Perhaps there's a magical guitar that Harry and Ginny find. It has special powers, like when Ginny plays it, it can calm the most ferocious magical creatures. They go on a journey to figure out the origin of the guitar and along the way, their relationship deepens as they face various challenges together.
One idea could be that Harry and Ginny are swimming in a secret pool at Hogwarts that has some magical properties. Maybe the pool can change its shape or temperature based on their emotions. Another could be that they are having a swimming race to train for a Triwizard Tournament - like event for adults. And they use magic to enhance their swimming abilities in creative ways.
One idea could be that they face challenges in preparing for the baby. For example, Percy might be worried about how to keep the baby safe from all the mythological threats. Annabeth, on the other hand, could be focused on building a perfect nursery in a place that combines both their worlds, like a cabin in Camp Half - Blood that has modern comforts as well as ancient Greek charms. Another plot idea could be that they receive prophecies about the baby's future, which makes them both nervous and determined to protect the unborn child at all costs.
One plot idea could be that Hermione and Ginny team up to play a prank on Harry, but it backfires in a hilarious way. For example, they try to make his hair turn purple but instead it starts changing colors every few seconds. Another idea is that the three of them go on a secret adventure outside of Hogwarts to find a lost magical artifact. They face various challenges and their friendship is tested. And perhaps a plot where Hermione discovers a new spell that accidentally causes some chaos between Ginny and Harry's relationship, and she has to find a way to fix it.
One idea could be exploring their wedding planning and all the chaos that comes with it. Maybe Molly Weasley is over - involved and wants everything to be perfect, while Ginny just wants a simple ceremony. Another could be their first year of marriage, dealing with things like living together in a new home and adjusting to each other's habits.
