Well, in such fanfiction, it's fascinating to consider how Voldemort's view of Harry might shift. He might see Harry's memories of facing challenges and growing stronger through them. This could either make Voldemort more determined to defeat Harry as he realizes his strength, or it could potentially make him more hesitant as he sees the full scope of Harry's experiences.
In the original story, Voldemort doesn't have access to Harry's memories in this way. So in the fanfiction, it creates a completely new scenario. It allows for a different kind of exploration of their relationship. Instead of just their physical and magical battles, we get to see a more psychological interaction.
Harry might become more cynical. Since Voldemort has seen a lot of dark and cruel things, those memories could taint Harry's view of the wizarding world. He could start to question the motives of people around him more, even those he once trusted, like Dumbledore.
Well, in the fanfiction about Voldemort's memories, there could be revelations about his relationships. For example, his connection with his mother, Merope Gaunt. His memories might also show his first encounters with the idea of immortality and how he started to plan his Horcruxes. It can give a deeper understanding of his motives.
One possible implication is that Harry would gain a deep understanding of Voldemort's motives. He might see how Voldemort's past traumas, like being an orphan and feeling rejected at Hogwarts, led him down the dark path. This could make Harry more empathetic in a strange way, or it could also be a huge burden on him as he has to deal with all the dark and twisted thoughts that Voldemort had.
The magic within Hogwarts could be influenced by Harry's memories. If he remembers a time when he used powerful magic, the magic in the castle might resonate with it. This could lead to strange phenomena, like the secret passages opening on their own as if they are reacting to the power within Harry's recollections.
Maybe in the fanfiction, Snape watches Harry's memories in an attempt to find some hidden secrets. He could be looking for clues related to Harry's connection with Voldemort. As he delves deeper into the memories, he might start to understand Harry's courage and loyalty in a way he never did before.
The plot could develop in various ways. For instance, they might discover a new lead on a dark wizard from Harry's memories. This could send them on a new adventure or mission.
One possible plot could be that the students and teachers at Hogwarts watch Harry's memories of facing Voldemort in the graveyard in 'Goblet of Fire'. They might be shocked and sympathetic, and it could lead to a greater understanding of Harry's burden. Another plot could involve Harry's memories of the Dementors affecting him, and as they watch, they figure out ways to help him better combat the Dementors' effects in the future.
Snape might become more empathetic. After seeing Harry's memories, he could understand the pain and pressure Harry has been under. This new understanding might make him more protective of Harry in some way.
