The relationship between Vanya and Allison in the show is complex and full of potential. In fanfiction, writers can explore their relationship in ways that the show might not have fully delved into. For example, they can focus on their sisterly bond, which has its own unique dynamics given their different powers and personalities.
One great place to start looking for Vanya Hargreeves x Allison Hargreeves fanfiction is Archive of Our Own (AO3). It has a vast collection of fan - created works. You can simply search for their names in the search bar, and it will show you all the relevant fanfics. Another option could be Fanfiction.net, though AO3 generally has more diverse and inclusive content in this regard.
One way to approach this in fanfiction is to focus on the emotional turmoil. Allison might be feeling scared, confused, and alone. Writers could explore how she copes with the situation, perhaps turning to her siblings for support in a world that's already full of chaos. But it's important to handle it delicately as it involves a very young age and pregnancy.
A possible plot twist could be that the pregnancy is not what it seems at first. Maybe it's a false positive due to some strange power or situation in the fictional world she lives in.
One common theme could be the reactions of the other characters. For example, her family members in the story might have different responses to her pregnancy, ranging from joy to concern. Another theme could be how Allison herself deals with the pregnancy, whether it was planned or unplanned and how it affects her goals and relationships.
Another option could be FanFiction.net. However, the quality and quantity of stories might vary. It's also important to note that when you search, make sure to check the tags and summaries carefully to ensure it's exactly what you're looking for. Sometimes, the stories might not be exactly about Allison being pregnant but could be related in some other way.
Sure, Viktor Hargreeves was part of the comic universe. The character's portrayal might have some differences from the on-screen version, but the core elements remain.
