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.
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.
Well, it's hard to say who the 'best' is as it depends on personal taste. But some popular authors might include those who have a deep understanding of the characters. For example, some authors who have been writing for a long time and have a large following. They are often good at capturing Spencer's intelligence and Toby's more reserved nature.
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.
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.
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 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.
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.
In the Pretty Little Liars universe, Toby and Spencer are from different worlds in a way. Toby has his own troubled past, and Spencer is from a more privileged background. When they come together, it creates a lot of tension and chemistry. Fanfiction can play with this dynamic, showing how they overcome their differences. Also, their love - hate relationship at times in the show gives fanfiction writers a lot to work with. For example, they can write about how their arguments turn into passionate reconciliations.
