One idea could be that Lydia's younger sister discovers Liam's werewolf secret and has to keep it from Lydia. Maybe she stumbles upon him during a full moon transformation and they form an unexpected bond over the shared secret.
A romantic relationship is also possible. Maybe at first they annoy each other. But then one day, Liam sees Lydia's sister in a different light, like when she stands up to a bully at school. He starts to notice her kindness and intelligence. And for her part, she is drawn to his protectiveness and loyalty. As they get closer, they have to deal with Lydia's possible disapproval, which adds some drama to the story.
One possible fanfiction could be about Liam and Annie's secret adventure. They might decide to run away from the drama in 90210 for a day and explore a nearby abandoned place. Along the way, they could discover old secrets about the town and also deepen their relationship as they rely on each other in this unplanned journey.
Sometimes, it could be due to her own actions. Lydia might be overconfident and take risks that she shouldn't. For instance, she could try to perform a very difficult and dangerous magic spell without proper training, and it backfires, causing her to get hurt.
It depends on your perspective. Some might find it inappropriate as it involves creating fictional scenarios about a real person in a rather personal situation like pregnancy. However, in the world of fanfiction, as long as it adheres to the rules of the platforms and doesn't cross into slander or overly offensive territory, it can be seen as a form of creative expression by fans.
Annie, on the other hand, is usually portrayed as a sweet and determined girl. She has her own dreams and goals, and she doesn't let anyone stand in her way. In the fanfiction, she might be involved in school plays or other activities that show her passion.
Well, at first, they would probably be overjoyed and their relationship would be filled with excitement. But as the pregnancy progresses, stress could set in. Maybe they would start to argue more about things like baby names, nursery designs, or how to raise the child. However, overall, the shared experience of the pregnancy would most likely strengthen their bond. They would have to make decisions together, like choosing a doctor, and this would bring them closer in the long run. Also, they would have to support each other through any pregnancy - related scares or difficulties.
I'd recommend 'Lydia's Hidden Powers'. This fanfiction delves deep into Lydia's potential powers that were perhaps not fully explored in the original. It has a lot of action and character development. You'll find yourself hooked from the very first chapter as it builds up the mystery around Lydia's newfound abilities.
Often, peter lydia fanfiction focuses on their relationship. It might explore their personalities in more depth compared to the original source. For example, if they were minor characters before, fanfiction can give them more backstory.
