It was Sasha Pieterse. She did a great job of differentiating between Alison and her twin, even though they were played by the same person. She was able to show different personalities and mannerisms for each character, which was really impressive.
The existence of Alison's twin added a major twist to the story. It explained some of the strange appearances and disappearances that had been confusing the other characters. It also brought in new layers of mystery and danger as the twin had her own motives and secrets.
One common theme is love and redemption. Their relationship in the show had so many ups and downs, and in fanfiction, often they are exploring how to truly love each other and redeem themselves for past mistakes. Another theme is mystery, as they still have to deal with the secrets of Rosewood even in their relationship.
Alison can be a great character in fanfiction too. Writers can play with her mysterious side. They might show her as someone who is trying to redeem herself for all the mean things she did in the past. In some fanfictions, she uses her intelligence to solve the mysteries that still lurk in Rosewood, all while being in a relationship with Emily.
Another storyline might be a time - travel fanfiction. Imagine Emily and Alison going back in time to before all the A - related chaos started. They could try to prevent some of the bad things from happening, like Alison's disappearance. Along the way, they might also discover some long - hidden secrets about their families and the history of Rosewood.
Well, there's this fanfiction called 'Emily and Alison: The College Years'. It's really good as it takes their story into the college setting. They experience new things, meet new people, but their bond remains strong. Also, 'Finding Each Other Again' is a story where they get separated for a while but then find their way back to each other. It has a lot of emotional moments that are really well - written. There's also 'Under the Rosewood Stars' which has a really romantic take on their relationship.
I really like 'Emily and Alison's New Beginning'. It's a fanfiction that focuses on a fresh start for the two. It has some interesting plot twists, like how they navigate their relationship while also dealing with new threats in Rosewood. It's a really engaging read if you're a fan of their relationship in Pretty Little Liars.
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.
Their relationship in fanfiction is appealing because it's complex. They have a history full of secrets and drama. In fanfiction, writers can explore all the unsaid feelings and the what - ifs. For example, they can write about how they might have fallen in love earlier if not for all the chaos in Rosewood.
Their friendship can be developed further by having them share more personal secrets. For example, Hanna could tell Alison about her insecurities regarding her family's financial situation even after things got better. Alison, in turn, could open up about her fears of losing her friends again. They could also have more adventures together, like exploring an old abandoned house in Rosewood and relying on each other during the spooky moments.
