Obviously, Lily is one of the main characters. And her friends, though we don't know their names yet from just this title, are also main characters. They are likely to be students at Hogwarts with different personalities and magical abilities.
It could be about Lily and her friends exploring the magical world of Hogwarts in a game. Maybe they are on a quest to find a hidden magical artifact within the castle. They might face challenges like solving puzzles created by the Hogwarts founders.
They could also face some challenges during the tag game. Maybe there are magical creatures that get in the way or some enchanted objects that cause unexpected things to happen. For instance, they might accidentally trigger a spell on an old statue that then starts chasing them, adding an extra layer of danger and excitement to their tag game.
It's hard to say who would win. If Lily is very fast on her feet and has a good knowledge of the Hogwarts grounds, she could have an edge. But if one of her friends has a special magical ability like being able to fly without a broom for a short time, that friend might win. It really depends on how they use their skills and the environment around them.
Many fanfictions portray Lily Luna Potter as a very friendly and inclusive character. She is likely to have friends from all the houses in Hogwarts. This is because she values the unity among witches and wizards, and she believes that everyone has something unique to offer, regardless of their house affiliation. So she is often seen as a unifying force within the Hogwarts community.
One possible plot could be that Lily has to face the challenges of being a pregnant student at Hogwarts. She might have to deal with the reactions of her friends and professors. Maybe she'll try to hide it at first out of fear of being expelled or judged.
Hermione's friends would likely be very excited. They might plan some special activities for her parents. For instance, they could arrange a little tour of the Forbidden Forest (from a safe distance, of course). They would also share stories about Hermione at Hogwarts, how smart she is and all the adventures they've had together. And they would be happy to answer any questions Hermione's parents had about the wizarding world.
Well, one possible plot could be that they face a lot of challenges. Their friends might be shocked at first. They'd have to deal with their studies while also preparing for a baby. And they might worry about how the Hogwarts faculty would react, whether they'd be allowed to stay in school.
Yes, there might be such fanfictions in the vast world of Harry Potter fanfiction. However, this is a rather non - canonical and often controversial topic as it goes against the original spirit and story line in many ways. But some fanfiction authors like to explore 'what - if' scenarios that are far from the original plot.
