Aria might become more mature. With the responsibility of a pregnancy, she would have to think more about the future and be less impulsive. For example, she might stop getting involved in some of the riskier adventures in PLL.
For Aria, you could show her growing more empathetic. Maybe she starts volunteering at a local pregnancy center to learn more about what to expect. She could also become more assertive in asking for what she needs from Jake, like help with household chores. Jake, on the other hand, might become more responsible. He could start reading parenting books and become more involved in the financial planning for the baby.
One common theme could be the reactions of the other characters. For example, how her friends in the PLL group handle the news. Another might be how Aria herself copes with the pregnancy, like dealing with morning sickness and hormonal changes.
Well, it could be that Aria's pregnancy is a result of a one - time accident. In the fanfiction, she might struggle with the decision of whether to keep the baby or not. Her friends in PLL, like Hanna, Spencer, and Emily, could have different opinions and offer their support or doubts. And then there's the whole thing about how the pregnancy will affect her future, like her education and career plans.
I don't have a specific PLL Aria pregnant fanfiction to recommend. However, you can look for it in fanfiction communities. Sometimes, on Tumblr or Reddit's fanfiction - related subreddits, fans might share or discuss such stories. You can also join PLL - focused fan groups on Facebook where members could potentially point you to relevant fanfiction.
Her friends like Spencer, Hanna, and Emily would likely be there for her. They've been through a lot together in PLL, so they'd probably offer support and understanding.
Aria's pregnancy in fanfiction would add a huge amount of drama to the story. It could lead to new mysteries or secrets. Maybe there are some unknown factors about the pregnancy itself, like health issues or something strange about the timing. This could tie in with the overall mystery - filled atmosphere of Pretty Little Liars. Also, it would give the writers (of the fanfiction) a chance to explore different themes such as motherhood, responsibility, and the consequences of young love.
Will would likely become more protective. He has always been brave, but now he has someone else to look out for. Elizabeth, on the other hand, might become more nurturing. She was already strong - willed, but the pregnancy could soften her in some ways.
The OC could also develop in terms of her powers. Maybe the pregnancy enhances or alters her powers in some way. This could lead to new story arcs where she has to learn to control these new aspects of her abilities while also dealing with the physical and emotional changes of pregnancy. For example, if she has telekinetic powers, the pregnancy might make them stronger but less stable at times.
Another potential antagonist could be a new character. Maybe someone who has a vendetta against Aria's friends and is using Aria as a way to get to them. This new character notices that Aria is tired and weak, so they target her specifically, causing more chaos and confusion in the PLL fanfic world.
Perhaps Aria has been working hard on some sort of project in the PLL world, like a school assignment related to the mystery they are all involved in. She's tired but determined. The fanfic could show her friends rallying around her to support her, and together they start to piece together more clues about 'A' as she rests and regains her strength.
