Another possibility is that it's a moment of defiance. Harry, despite being in a dangerous situation with Voldemort, shows his courage by squinting at him. It's like he's saying 'I'm not afraid of you' even though Voldemort is one of the most powerful dark wizards. This can add a lot of tension and drama to the fanfiction scene.
In many fanfictions, Harry Potter squinting at Voldemort could be a sign of intense focus. It might be that Harry is trying to read Voldemort's next move, or perhaps he's looking for some sign of weakness. For example, in some stories, Harry's squinting could be related to his newfound magical abilities that he's using to analyze Voldemort's magic signature.
Use body language. Harry could be standing tense, his hands clenched into fists while he squints. This shows his determination. And for Voldemort, you can describe his reaction to being stared at in such a way. Maybe he sneers or his red eyes flash with anger. 'As Harry squinted, Voldemort's lips curled into a cruel sneer, his eyes flaring.' This creates a dynamic between them.
One possible fanfiction could be that Harry Potter is kidnapped by a dark wizard who has some strange power that makes Harry squint. Maybe this wizard is trying to use Harry's unique connection to Voldemort for some dark ritual. Harry has to use his wits and the few spells he can manage while squinting to try and escape.
It could mean a fan - made story (fanfiction) where Harry Potter is looking closely or suspiciously at a snake. Maybe in this fanfiction, the snake has some special significance, like being related to Slytherin or having some kind of magical power that Harry is trying to figure out by squinting at it.
There could be a fanfiction where Harry is studying in the library with his broken glasses. He's squinting hard to read the old, faded texts. Hermione notices and offers to help him fix his glasses with a spell she's been researching. But Harry refuses at first, wanting to do it on his own. This creates a bit of tension between them, and as they argue, Ron comes in and tries to mediate. It could be a comical and character - driven fanfiction scenario.
He could be squinting because he's trying to read Shacklebolt's expression carefully. Harry has been through a lot and has learned to be cautious. Maybe he's looking for any sign of deception or unease in Shacklebolt's face.
It might also indicate a newfound curiosity. Fanfiction often takes characters in different directions. Harry could be squinting at Malfoy because he's starting to see a different side of him. Maybe he's noticed something that makes him think Malfoy isn't all bad, and the squint is his way of trying to understand this new Malfoy better.
It's possible. In the realm of fanfiction, the imagination knows no bounds. Writers might come up with such a scenario for various reasons, perhaps to explore a different side of the characters' relationships. But it's not a common or mainstream concept within the Harry Potter fanfiction community, as it goes against the typical character dynamics we expect from the series.
It could be that Harry has noticed some strange behavior from Malfoy. For instance, Malfoy might be acting secretively around certain areas of Hogwarts. Harry's squinting is his way of observing Malfoy closely to find out what he's hiding.
In this fanfiction, it could be that Voldemort has a premonition. He sees that if Harry Potter dies, it will lead to a series of disasters that will also destroy his own plans. So, in order to preserve the balance or to keep his long - term goals intact, he saves Harry. For example, if Harry's death causes an uncontrollable chaos in the wizarding world, Voldemort's rule over the dark forces might be disrupted. So he steps in to save Harry.
One possible fanfiction could be about Harry having trouble with his glasses after a spell goes wrong. He has to squint constantly to see clearly, and this leads to some comical situations at Hogwarts. For example, he mistakes a cat for a Kneazle during Care of Magical Creatures class.
