In this fanfic, perhaps Harry stumbles upon the portraits while exploring a hidden part of Hogwarts. He might have an emotional moment as he sees his parents for the first time in this way, and the portraits could start interacting with him, sharing long - lost memories and advice.
One possible plot could be that Harry is on a quest to find something related to his parents, and in the process, he discovers their portraits. The portraits could be enchanted in a special way. They might not be just ordinary portraits but ones that can move around Hogwarts and lead Harry to important places or people. Harry could have conversations with them, learning about his parents' early years at Hogwarts, their friends, and their hopes and dreams. This discovery could also give Harry a new sense of purpose and strength, knowing more about his family heritage.
Obviously, Harry's parents, James and Lily, would be main characters as their portraits are central to the story. Dumbledore could also be an important character. He might be the one who either hid the portraits or knew where they were all along and guides Harry to them.
Well, it could be that Harry meets his parents through some magical time - turner accident. Maybe he's on a mission in the past and stumbles upon them.
Well, it could be that Naruto is on a mission and accidentally uncovers a powerful jutsu that has the power to show the past. And through this, he sees his parents. His father might give him some advice on how to become a better ninja or how to handle the power within him. His mother could tell him how much she loved him and why they had to sacrifice themselves. Then Naruto could use this new understanding to face his enemies more bravely.
There could be some of his parents' old school things like their Hogwarts robes, wands (if they were allowed to keep them), and textbooks. Maybe there are also some love letters between his parents or photos of their time at Hogwarts.
In this fanfiction, Harry might have a magical encounter where his parents' spirits guide him. Maybe they reveal secrets about his family's past that Dumbledore had been keeping from him for his own protection.
It could be that his parents were trying to protect Harry in a really messed - up way. They might have thought that by 'betraying' him, like sending him away or making him seem like an outcast, they could keep him safe from a much greater threat. Maybe they knew some prophecy about Harry and thought this was the only way to ensure his survival. They might have made a deal with some dark force, believing they could outwit it in the end but ended up being seen as traitors by Harry and others.
The portraits could offer him emotional support. Just seeing his parents' faces might give Harry the strength to face difficulties. For example, when he's feeling down or facing a tough decision, looking at the portraits could be like getting a warm hug from his parents, even if they're not physically there.
Well, it could be about Harry Potter finding a will left by his parents. Maybe in this fanfiction, the will contains secrets about his family, his heritage, or some sort of magical items or powers that were meant for him. It might also reveal things about his parents' past and their relationships with other characters in the wizarding world.
He would probably be overjoyed. Harry has always longed for a connection with his parents. Getting their portraits would be like getting a part of them back. He might just stand there, staring at the portraits with a big smile on his face, unable to take his eyes off them.
One way is that Harry discovers a spell that allows him to communicate with the dead. Using this spell, he contacts his parents. They give him advice on how to defeat Voldemort, like a secret weakness of the Dark Lord.
