In some fanfiction, there might be a scenario where Toby and Jenna were never really enemies like they seemed. Instead, they were forced into their roles by someone else. So, they could join forces to expose this person who has been manipulating them all along. This would be a big twist on their relationship in the original show.
Another scenario could be that Toby discovers Jenna has a completely different side to her that she has been hiding. Maybe she's been acting tough but is actually very vulnerable. Toby could then become her protector in a way that changes the dynamic between them and also affects how they interact with the other characters in the Pretty Little Liars world.
In some fanfictions, Toby might develop from a brooding and mysterious character into a more open and trusting person, especially when it comes to Jenna. He could start to see the good in her, despite all the bad things she has done in the past. For Jenna, she could develop from a seemingly cold - hearted antagonist to someone with more depth and a tragic backstory that explains her actions.
One interesting storyline could be them solving a mystery together that is separate from the main 'A' plot in the show. They use their combined intelligence and Toby's skills to uncover something that has been hidden in Rosewood for years.
A possible plotline is that Toby and Spencer get married in a secret ceremony. But then they face challenges when the truth about their marriage gets out. The other Liars might have mixed reactions, some being happy for them while others worried about how this will affect the group dynamic and their safety from the ever - lurking A.
One interesting storyline could be their future together. Maybe they move away from Rosewood and start a new life, away from all the drama. They could be building a house and planning their wedding at the same time.
One interesting Emily and Toby fanfiction could be about them teaming up to solve a mystery in Rosewood that's not related to 'A'. They might use their unique skills, with Emily's athleticism and Toby's knowledge of the town's secrets, to figure things out.
The Jenna story in Pretty Little Liars is quite complex. She has a history of being involved in various mysterious and sometimes sinister events related to the main characters.
A really interesting plot could be set in an alternate universe where Toby is a detective and Spencer is a journalist. They team up to investigate a series of strange disappearances in their town. As they dig deeper, they start to realize that there are forces at work that are much bigger than they initially thought. Their relationship evolves from professional partners to something more romantic as they face danger together.
There are many great writers out there. Some popular ones are often those who are really good at capturing the personalities of Spencer and Toby as they were in the show. For example, some writers on fanfiction.net have a large following for their PLL fanfics. But it's really subjective, as different people like different writing styles.
One of the best elements is the exploration of their complex characters. In fanfiction, we can see different sides of Emily and Toby that might not have been fully explored in the show. For example, we can see how Toby's troubled past affects his relationship with Emily on a deeper level.
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.
