One possible plotline could be that Blaine's friends rush to his side after he gets shot. They then try to find out who the shooter is while also dealing with their own emotions. Maybe there's a mystery involved, like the shooting was a case of mistaken identity.
It could be a random act of violence by a criminal who was in the wrong place at the wrong time. There are some bad elements in the area where Blaine was and they just targeted him without any specific reason other than opportunity.
Perhaps a mysterious stranger who has some unknown vendetta against the Heartland family. This person could have been lurking around the ranch for a while, waiting for the perfect opportunity to strike. Or it could be someone within the community who has a hidden agenda and sees Amy as an obstacle to their plans.
In many 'Katniss gets shot' fanfictions, she might face a life - threatening situation. Her friends could rush to her aid. For example, Peeta might use his skills to protect her further while waiting for medical help. Maybe Gale tries to find the source of the shooter and avenge her.
One possible plot development could be that his friends and family rally around him. They might search desperately for the person who shot him. For example, if it was a case of mistaken identity, they could start to dig into Sam's recent activities to find any leads. Maybe they discover that Sam was unknowingly involved in something dangerous, like being in the wrong place at the wrong time during a criminal deal. This could lead to a whole new sub - plot where they try to figure out who the real target was.
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.
If Spiderman gets shot in fanfiction, it could lead to a very different story arc. He might have to rely on his friends and allies more. For example, he could call on Iron Man for some high - tech medical help or MJ could be there to nurse him back to health. His powers might also be affected, and he could struggle to keep up with his usual crime - fighting duties while he recovers.
Well, it could be that the raven is a special or magical raven. Maybe it was flying over a restricted area and got shot by a hunter who didn't realize its importance. Then, the story could follow how the raven's friends or family try to save it or seek revenge on the shooter.
