Well, they could get involved in a mystery that is separate from the main PLL drama. For example, there could be a series of strange events happening in their neighborhood, and they team up to solve it. They might also have a falling out over a boy, but then realize their friendship is more important and work through it in a really emotional way.
A great plot could be that Hanna and Emily are both having strange dreams that seem to be connected. They start to investigate these dreams and find out that they are linked to an old family secret. As they dig deeper, they face many obstacles, like people trying to stop them from uncovering the truth. Along the way, their friendship is tested but also grows stronger as they support each other through the tough times.
Well, they could start a business together, like a small café or a fashion boutique. This would bring in a whole new set of drama as they deal with competitors, financial issues, and their own personal relationships. Maybe there's a love triangle involved where both of them are interested in the same person who also has some connection to their new business.
A plot could involve Aria and Hanna starting a fashion business together. Since Hanna has an interest in fashion, and Aria has her own unique sense of style. They could face challenges like dealing with a rival who is trying to steal their designs. This would test their friendship and their ability to work together.
A plot could involve Hanna and Mike starting a school project together and during the process, they discover a hidden connection between their families. This connection could be related to the events in Pretty Little Liars, like a shared secret from their parents' past.
Perhaps Hanna discovers that Lucas has a connection to one of the early victims of 'A'. They team up to dig deeper into this connection, which leads them to some dark secrets about the town's past. Along the way, their friendship strengthens and they support each other through the tough revelations.
One interesting plot idea could be that Hanna and Alison find themselves in a parallel universe where their roles in the group are reversed. Hanna is the popular and feared one while Alison is the more insecure. Another could be a time - travel plot where they go back to before Alison's disappearance and try to prevent all the bad things that happened later. Or perhaps a plot where they team up to solve a mystery that is related to their families' pasts.
In some fanfictions, Emily's pregnancy might be part of a larger conspiracy. For example, someone could be using her pregnancy to manipulate the other characters. Or perhaps her pregnancy is a result of some sort of experiment gone wrong in the Pretty Little Liars universe. This would make for a really exciting and unique fanfiction plot.
The moms of Emily and Hanna could be great characters to include. Their parenting styles and the secrets they might be hiding can add a whole new layer to the fanfiction. Also, Paige, Emily's ex - girlfriend. Her presence can stir up old feelings and create some tension in the story, especially if there are new love interests for Emily.
One scenario could be that Hanna and Wren meet by chance outside of Rosewood. Wren is intrigued by Hanna's newfound confidence and Hanna is drawn to Wren's charm. They start to bond over their shared love for art, as Hanna has developed an interest in it after all she's been through in Rosewood.
One interesting moment could be when they team up to solve a mystery in the fanfiction world. Maybe they find a clue that no one else has noticed and it deepens their friendship.
One interesting plotline could be Caleb and Hanna facing a new mystery together in a post - show fanfiction. Maybe they move to a new town and start to notice strange things happening around them, just like in the original show.
