Alexis could also try to engage in discussions with other fans of Beckett. By sharing her/his views, Alexis might gain new perspectives and either change her/his mind about fanfic in general or at least find a subset of fanfic that she/he can tolerate.
One way could be for the writer of the fanfic to rewrite Brick's character to be more palatable to Blossom. Maybe make him more heroic or less antagonistic.
Maybe Alexis has a different vision of the original story or characters. Fanfic often takes creative liberties that might not align with Alexis's view of Beckett.
Alexis might confront Beckett directly. She could say something like 'I think you're cheating on me. What's going on?' This is a very straightforward approach.
He could also gather evidence of Alexis' attempts to hurt him. If it comes to it, he can use this evidence to expose her actions to those around them, like mutual friends or authorities in their fictional world. Another way is for Beckett to strengthen his own defenses, both physically if it's a more action - oriented fanfic, and mentally by not letting Alexis' actions get to him.
She could be defensive of Beckett. Since Alexis probably has a good relationship with Beckett, she may try to convince Castle that he's wrong and that Beckett didn't mean any harm. For example, she might tell Castle about all the positive things Beckett has done for her.
The author of the fanfiction could rewrite it to better align with the characters' personalities. For example, by making Percy more in - character and the high school setting more unique.
Communication is key. They could sit down and talk about their misunderstandings. Once they clear the air, their relationship might improve.
A common theme is friendship. Many fanfics explore how Beckett and Alexis become friends and the bond they share. Another theme is growth, as they both develop as characters within the fan - created stories.
Well, without having read the actual 'beckett and alexis killed fanfic', it's difficult to give a detailed account. However, generally speaking, it might be a piece of fan - made fiction that focuses on a plot where Beckett and Alexis are somehow related to a killing. Maybe they are the ones who do the killing, or perhaps they are witnesses or victims in a more complex scenario.
Sure. You can try searching on platforms like Archive of Our Own. There are often some well - written fanfics about Beckett and Alexis that range from adventure - themed ones where they go on quests together, to more character - study - like fics that explore their relationship in depth.
