A frequent plotline is the impact on her relationships. Her romantic partner, if she has one in the fanfiction, might be completely devastated. Her family members, like her mother or sister, could also be major players in the story, either seeking revenge or trying to move on from the loss.
In the fanfiction, perhaps Artemis decides to take on a more solo approach to her vigilantism. She may feel that with her mom gone, she can't rely on anyone else in the same way. This could lead to conflict within the Young Justice team as they try to bring her back into the fold. Also, she might start investigating the circumstances around her mom's death more closely, uncovering secrets that put her in danger.
Her relationship with Wally could become more strained. He might not know how to comfort her, and she could push him away because she doesn't want to be seen as weak.

One common theme is her growth as a hero. Writers often explore how she overcomes her insecurities and becomes a more confident and capable member of the team.

The fanfictions also might show the team trying to keep her memory alive, like by creating a memorial or doing things she used to love in her honor.
There's a fanfic called 'Trans Artemis: Finding Her Place'. In this one, Artemis is not only dealing with her trans identity but also her role in the team. It shows her growth as she overcomes insecurities and prejudices. It has some really heartwarming moments between her and other characters like Wally, who is very supportive.
Some common themes include her family dynamics. Since Artemis has a complex family background, her relationship with her mother and sister often features. Another theme is her training.

Friendship is a very common theme. Since they are both part of the Young Justice team, many fanfictions explore how they become friends and support each other through various challenges.
One possible plotline could be that Percy sacrifices himself to save Artemis from a powerful and ancient enemy. Maybe there's a prophecy that foretells his death in order to protect her.

And perhaps in his death, he becomes a symbol of heroism that changes the way the gods view demigods.

The kiss could be a turning point where they admit their real emotions to themselves.
