In this fanfiction, it could be that Paul is under the influence of some evil force or has been manipulated. This makes him do things that go against his true nature. As a result, he feels so guilty and ashamed that he wants to end his life. His Pokemon might be his only hope. For example, his starter Pokemon could have a special bond with him and use that bond to reach out to his heart and prevent him from going through with the suicide attempt.
Merlin could use his magic to show Harry visions of a better future. By giving him hope, Harry might change his mind. For example, Merlin could show Harry how his actions in the future would lead to great good.
Harry might be shocked and full of regret. He had finally come to understand Snape's true nature in the original story. In the fanfiction, if Snape tries to kill himself, Harry could feel that he had not done enough to reach out to Snape or show him some form of forgiveness or acceptance, and he would likely be deeply troubled by it.
In such a fanfiction, one possible reason could be his feeling of extreme isolation. After his estrangement from his family, he might have felt completely alone in the wizarding world. He was always so focused on rules and order, and when things didn't go as he planned, especially in his career and family relationships, it could have pushed him to this dark place.
One possible theme could be bullying and its extreme consequences. Bakugou's statement is an extreme form of bullying, and the fanfic might explore how such words can deeply affect Deku's mental state. Another theme could be redemption. Maybe the story will show Bakugou realizing the gravity of his words and trying to make amends. It could also touch on the theme of friendship, as Deku might have to decide whether to forgive Bakugou and rebuild their relationship.
At first, it could be extremely strained. Deku might be terrified of Bakugou and avoid him at all costs. But as the story progresses, if Bakugou realizes his mistake, he could start trying to make it up to Deku. Deku, on the other hand, might be hesitant to accept Bakugou's apologies at first, but over time, they could start to rebuild a more positive relationship based on mutual respect.
It might handle it by showing the psychological state of Paul very clearly. Through his internal monologues, the readers can understand his pain and desperation. For example, it could describe how he looks at his Pokemon team and feels like he has let them down, which adds to his sense of failure.
His family would likely be in shock at first. The Weasleys are a close - knit family, and even though Percy had his differences with them, they still care deeply for him. They might feel guilty for not reaching out more or for being too harsh on him during their arguments.
The way the fanfiction portrays his relationships can also show despair. If his friends try to reach out but he shuts them off, it's like he's in a deep hole of despair where he doesn't believe anyone can help. And his actions, such as isolating himself in a dark place, could be symbolic of his state of depression.
One possible reason could be his overwhelming guilt. Snape had a complex past, being involved in the Death Eaters and then switching sides. He might have felt that he could never truly be redeemed, especially with all the lives lost during the wizarding war that he had some part in, whether directly or indirectly. This guilt could have driven him to such a desperate act.
