At first, it might be a bit awkward as they get to know each other. But then they would grow closer. His grandparents would probably dote on him and Harry would come to rely on their love and support.
He would likely be more confident. Growing up with his grandparents, who presumably love and support him, he wouldn't have the self - doubt that came from living with the Dursleys. He would be more self - assured in his magical abilities from the start.
Harry might be more self - assured. Since his grandparents are likely to be more loving and supportive than the Dursleys, he would grow up with a better sense of self - worth. He could be more open - minded as well, because his grandparents' different parenting style would expose him to different ideas and ways of thinking.
The relationship could develop in a complex way. They might compete with each other at first, like in a magical duel to prove who is the better Harry. However, after that, they could start to respect each other. The parallel Harry might show the original Harry a different perspective on his life, and this could lead to a deep friendship or even a brother - like bond.
At first, it would be really rocky. Harry would be suspicious of Snape and Snape would be his usual grumpy self. But over time, as they get to know each other better, they might start to respect each other. Harry could learn about Snape's past and his complex relationship with his mother, which might soften his view of Snape.
Their relationship could develop in a really interesting way. Since Aaron is used to dealing with complex personalities in the BAU, he would be patient with Harry. He'd start by just observing Harry, learning his habits and fears. As time goes on, he'd open up more about his own past and experiences, which would make Harry feel closer to him. They could also have some father - son adventures, like exploring hidden parts of Hogwarts together or facing off against some of the darker forces in the wizarding world.
He might be more old - fashioned in his ways. His grandparents' values would likely have a big influence on him, so he could be more reserved and traditional compared to the Harry we know from the original series.
The relationship might start with Naruto being a bit resentful at first for being left alone all those years. But as his father explains the reasons behind his actions, Naruto would gradually understand and they would form a deep bond. They could go on adventures together, with Naruto's father showing him secret places in the ninja world and teaching him how to use his Uzumaki heritage to its fullest. This would make Naruto even stronger and more confident in his abilities.
If Artemis is sick, Harry Potter might start by showing concern and offering help. This could be the start of a friendship. Harry could share his experiences of facing difficult situations at Hogwarts, which might give Artemis the strength to fight his sickness.
Perhaps his grandparents were great adventurers in their time. They could have traveled to far - off magical lands and encountered strange and wonderful things. Their experiences could be passed on to Harry, inspiring him to explore more of the wizarding world and its secrets. They might also have been involved in some great battles in the past, and their war stories could give Harry valuable lessons for his own fight against Voldemort.
They could be very traditional and strict pure - blood wizards. Maybe they were part of some ancient magical order and had high expectations for the Potter family. They might be disappointed in how James and Lily Potter deviated from some of the old ways, but be very proud of Harry when they get to know him.
