She might survive due to her strong will and the help of her friends. Maybe they find a healer or some magical cure in time.
Well, it depends on the context of the fanfic. If it's in a world where magic is prevalent, there could be a spell to reverse the damage of the shot. However, if it's more of a gritty, realistic take on the situation within the fanfic's universe, she could be in for a long and difficult recovery. Her injury might also be a catalyst for some major plot developments, like a change in the relationships between the characters or a new threat emerging that they have to deal with while also trying to save her.
It could be a random enemy, like a rogue monster that manages to catch her off - guard.
Well, in this fanfic, the setting of getting a flu shot could be really interesting. It could be at a Muggle hospital that Harry and his friends visit secretly. The nurse giving the shot might be completely unaware that she's dealing with a famous wizard. Harry might be thinking about all the potions he's had at Hogwarts and comparing them to this strange Muggle medicine. He might even wonder if there's a way to make a potion that works like a flu shot so that wizards don't have to go through this somewhat scary process.
In this kind of fanfiction, perhaps Annabeth might start acting out of character. She could say things she normally wouldn't. For example, she might be more open about her feelings towards her friends or reveal some secrets she's been keeping.
In this fanfiction, perhaps Annabeth getting shot is a turning point for her character. She could start to question her own safety and the safety of those around her. Her friends might go on a hunt for the person who shot her, leading to a lot of action and adventure. It could also lead to some emotional moments between her and her closest friends, like Percy, as they worry about her survival.
Maybe it's a human who has somehow discovered the world of demigods and is afraid of their existence. They shoot Annabeth out of fear and misunderstanding. Another option is that it's a rogue demigod who has gone bad and is working against their own kind. This character could have a personal grudge against Annabeth specifically, perhaps because of her intelligence and leadership skills which they envy.
Well, he could be magically healed by one of his friends. Maybe Lucy uses her celestial magic to call a spirit with healing powers.
Well, depending on the plot of the fanfiction, her partner could go on a vendetta against the person who shot her. He would be filled with rage and determination to bring the perpetrator to justice. Meanwhile, Kensi in the hospital would be fighting for her life, with flashbacks of her past and her relationships running through her mind.
Well, in such a fanfiction, Conan could end up in a critical condition. Maybe he'd be rushed to the hospital where his friends would be worried sick. They might start investigating who shot him and why.
The fanfic could also take a more complex turn. Annabeth gets pregnant at a time when there are threats to the world. She has to deal with the fact that she's bringing a new life into a potentially dangerous situation. There could be a prophecy related to her unborn child, which adds more drama. Her pregnancy might also be a sign of hope for the future of their world, as the child could be a great hero in the making.
Another reason could be jealousy. Suppose Percy was getting a lot of attention and praise for his recent achievements, and Annabeth felt overshadowed. Her jealousy could fester and turn into a desire to undermine Percy, leading to her betrayal. However, this would be a more complex and less noble reason compared to the others.
