Another consequence could be that it sets off a chain of events related to the overarching plot of the fanfiction. Maybe the glasses have some hidden magical property that, when given to Harry by Malfoy, activates a prophecy or a long - lost magical power. This would then lead Harry and Malfoy to be involved in a much larger adventure together, whether they like it or not.
One possible consequence is that he might get injured more easily. Without his glasses, his vision is impaired, and being blindfolded makes it even worse. He could trip over things, bump into walls or other objects, and get bruises or cuts.
Maybe it's a moment of unexpected kindness. In some fanfictions, Malfoy could be having a change of heart. He might see Harry in a difficult situation without his glasses and, for a brief moment, decides to be helpful rather than his usual antagonistic self.
One possible plotline could be that Harry loses his glasses during a crucial event, like a battle or a chase in the Forbidden Forest. Malfoy finds him in this vulnerable state and has to decide whether to help or hinder him. This could lead to a moment of unexpected kindness from Malfoy or a new level of animosity.
He might have more free time for other hobbies like reading regular books or watching movies.
One consequence could be that his fans in the fanfiction community will be disappointed. They might have been looking forward to his new works.
One consequence could be that the fanfiction community would lose a significant source of inspiration. Since Harry was the main character, his departure from the fanfiction world might lead to a decrease in the quality or quantity of new works.
Well, it might also lead to a change in the dynamic among the characters. For example, Hermione or Ron might have to take on a more protective role towards Harry. They would need to be his eyes in a sense, guiding him and making sure he doesn't get into more trouble. Plus, it could be a plot device for the author to introduce some sort of magical solution to the problem, like a spell that temporarily restores Harry's vision without his glasses.
It could be really interesting. Maybe without his glasses, Harry would seem more vulnerable, and Malfoy might take advantage of that in a different way than in the original story. They could have more intense eye - to - eye confrontations that are different from the ones where Harry is hidden behind his glasses.
Well, for Harry, he might grow up with a sense of abandonment. In some fanfictions, this could lead to him having trust issues or a longing to find out about his real parents. For example, he might struggle with his identity, not knowing why his parents gave him away.
One consequence could be that his fans were disappointed. If he had a following for his fanfiction, they would no longer have new stories from him.
