The fanfiction could also depict the reactions of those around him. Some might be shocked, others might try to help. There could be a kind old wizard who approaches him, or a Muggle who is completely confused but still offers some form of comfort. This contrast between Harry's internal chaos and the external world's response can be a key part of how the breakdown is shown in the fanfiction.
Some fanfictions might describe his internal thoughts during the breakdown. He could be thinking about how alone he feels, even though he has friends. Words like 'Why is it always me?' might be running through his head as he stands on the street, the world around him seeming to close in.
Often, it might show him physically crumbling. He could fall to his knees, with his face in his hands, trying to hold back the sobs. His shoulders would be shaking, and his wand might even fall from his hand as he's lost in his emotional turmoil.
Often, Harry's knowledge of fighting in fanfiction comes from intense self-study and practice, as he realizes the importance of being well-prepared for the challenges ahead.
In some fanfiction, the immediate consequence of the Killing Curse is not always death. There could be a situation where the victim's soul is split, like what happened to Voldemort when he tried to kill Harry as a baby. This creates a complex situation where the victim may have a part of their being that is still 'alive' in a strange way.
Often, Snape is shown as having a more nuanced relationship with Harry. He may not be as cold or harsh as in the original story. Because Harry is the WBWL in a different context, Snape might realize the importance of guiding Harry more quickly. This could lead to him showing more of his true self, his intelligence and his complex emotions, rather than just the surly Potions master.
Often, fanfiction depicts their interaction as intense. Harry, being the hero, is usually in opposition to Grindelwald's dark plans. For example, he might try to stop Grindelwald from gathering more followers or retrieving some powerful dark artifact.
In regular fanfiction, the story usually revolves around the established magical world order. However, 'Harry Potter Street Smart' fanfiction can break those boundaries. For example, a street - smart Harry might team up with some Muggle inventors to create a new type of magic - Muggle hybrid device to defeat his enemies. This kind of creativity and deviation from the norm is what sets it apart. It gives a fresh perspective on the characters and their capabilities outside of the typical Hogwarts - centric storylines.
The novel depicts the breakdown by showing how the boys' behavior changes. They start to become more violent and less empathetic. They kill Simon in a frenzy, thinking he was the 'beast'. This act of violence is a clear sign of the breakdown of any sense of a moral and civilized society. Also, the lack of a proper system of justice on the island means that there's no way to stop this downward spiral into chaos.
The fanfiction usually depicts their relationship development in stages. First, they are just kids getting to know each other at the Burrow. Then, at Hogwarts, they start to become closer friends. They study together, play Quidditch together. As they mature, their feelings for each other become more complex. They might have some awkward moments, like blushing when they accidentally touch hands, which are all signs of their budding romantic relationship.
Often in fanfiction, 'Harry Potter breakdown' might explore the breakdown of relationships. For instance, the friendship between Harry, Ron, and Hermione could be strained. Ron might feel left out when Harry and Hermione seem to be getting closer in their fight against Voldemort. This kind of relationship breakdown can be a central theme in such fanfiction.
Street smarts often help the characters, especially Harry, in fanfiction. It allows them to make quick decisions in dangerous situations. For example, in some fanfics, when facing dark wizards in the alleys of Knockturn Alley, Harry's street smarts tell him when to fight and when to run.
He might give Harry detention. Harry could be made to clean the trophies in the trophy room or help Hagrid with some difficult tasks in the Forbidden Forest under strict supervision.
