Another good option could be a new character. For example, a transfer student from another country who has a different perspective on the 'A' situation. Aria could be drawn to this character's mystery and they could start a friendship or something more that helps Aria see things in a new light.
Aria might be paired well with Jason. Their families have a connection in the show, and in a fanfiction, they could explore that connection further. Maybe they start to have feelings for each other while also dealing with the secrets of Rosewood. For Spencer, Wren could be a good character to pair with. Wren has always had an on - again, off - again relationship with Spencer, and exploring their relationship more in a fanfiction could bring out a lot of emotions and drama, especially when considering how it might affect the other Liars.
It depends on what you specifically mean. If there is a piece of writing that features Aria from 'Pretty Little Liars' and it's not an official part of the show's storyline, then it could be fanfiction. Fanfiction can range from simple short stories to complex multi - chapter works. Maybe someone was really inspired by Aria's character arc in the show and decided to create their own story, which would classify as fanfiction.
It's really hard to say who the best writer is as it depends on personal taste. Some people might like writers who focus on the romantic aspect between Jason and Aria, while others prefer those who create more mystery - filled stories. However, many fans seem to enjoy the works of writers who are really good at capturing the essence of the characters' personalities from the show.
Aria could also be a good addition. Given her creative and artsy side, she might offer different insights compared to Spencer and Dean. She could also be involved in a love triangle situation, which would add more drama to the fanfiction. For example, if both Dean and Ezra were interested in Aria at the same time while she was friends with Spencer and Dean.
If Aria gets pregnant in fanfiction, she might have to make some tough decisions. She could consider keeping the baby and trying to raise it with Ezra, or she might think about other options like adoption. Her pregnancy could also be a catalyst for her character growth. She'd have to become more responsible and deal with the consequences of her actions, which could be interesting to explore in the context of the Pretty Little Liars world.
One great 'Aria and Ezra' fanfiction is 'The Unspoken Promises'. It delves deep into their relationship, exploring the unsaid emotions and the challenges they face outside of the main plot of 'Pretty Little Liars'.
Ezra could be a likely candidate as they have a complex relationship in the original series. It would add more drama to their already tumultuous love story if he were the father.
Another possibility is that one of Aria's friends accidentally causes her harm. For example, during an argument or a chaotic situation, they might say something really hurtful that emotionally wounds Aria. Or, in a more physical sense, if they were in a dangerous situation together and made a wrong move, it could lead to Aria getting injured.
One idea could be Aria exploring a new art form in Paris for a semester and getting involved in a mystery there related to the 'A' games. Maybe she meets a mysterious artist who seems to know more about her past than she does.
In some fanfictions, Jason and Aria could have a secret friendship that develops over time. Maybe they start sharing their secrets and fears with each other, which deepens their bond. For example, Aria could confide in Jason about her relationship problems, and Jason could offer his own experiences and advice. This could lead to a more complex and interesting dynamic between them compared to what we see in the original show.
