The loss of trust could lead to Harry making new alliances. Since he no longer trusts his old friends, he might seek out other characters who he believes are more trustworthy. This could introduce new sub - plots and characters into the story.
His loss of trust can also make the resolution of the main conflict more difficult. In a lot of Harry Potter - related stories, the power of friendship is crucial in defeating the main villain. If Harry doesn't trust his friends, it becomes a huge obstacle in the way of achieving victory against the dark forces.
Maybe his friends betrayed his secrets. In many fanfictions, a friend might accidentally or deliberately let out something Harry had confided in them, like his fears about Voldemort or his feelings for a certain girl. This could shatter his trust.
In some fanfiction, the author might create a plot where Harry has been betrayed before. So, he has trust issues even with his friends. For example, if he was tricked by someone who seemed like a friend in the past, it could make him more cautious and less trusting in new situations with his real friends.
In the fanfiction, Harry's lack of trust could lead to a lot of misunderstandings. His friends may misinterpret his caution as a lack of care for them. It could also isolate him. People might start to avoid him if they feel he is always doubting them. This isolation could then further fuel his lack of trust as he has fewer positive interactions with others, creating a downward spiral in his relationships.
His relationships would become very strained. Friends might feel hurt that he doesn't trust them, which could lead to arguments and distance. For instance, Hermione might be constantly trying to prove herself to him, but he still remains skeptical.
His lack of trust would surely strain his friendships. His friends might feel hurt and rejected by his constant suspicion. For example, Hermione, who has always been loyal to him, might be deeply disappointed if Harry doesn't trust her.
It could strain his relationships with some pure - blood wizards who are prejudiced against goblins. They might see Harry's trust as a betrayal of wizarding traditions.
His relationship with Ginny could also be affected. Ginny is a passionate Quidditch player herself. She might initially be sad that Harry is leaving the sport. But if she truly loves Harry, she will come to understand his reasons and support him. And Harry might feel guilty for disappointing Ginny, which could add some tension to their relationship at first.
His friends might be divided in their opinions. Some of them might still trust Dumbledore wholeheartedly and think Harry is overreacting. This could lead to arguments and a strain in their relationships.
His relationships would change a great deal. The friends who once knew Harry as a somewhat vulnerable and kind - hearted person would now have to deal with this new, cold - edged strength. Those friends who were closer to him for his softer side might drift away. However, some might see this as a positive change in a way, like they might think he's finally growing up and becoming more self - reliant. But still, there would be a lot of adjusting to do on both sides.
It creates a lot of tension. His friends will be confused and worried about him. This can lead to them trying to find out what's wrong with Naruto, which drives the plot forward as they search for answers.
