Harry's view of the world might change completely. He has seen so much darkness and death. With his parents' return, he could start to see the world in a more hopeful light. He may be more willing to forgive those who have wronged him in the past, like Snape. Their return would be a catalyst for a huge shift in his personality, making him more balanced and less haunted by his past traumas.
Harry would likely be overjoyed at first. After all, he never really got to know his parents. Their return could give him a sense of family and belonging that he's always craved. It could also help him deal with some of his past traumas, having his parents there to support him.
Harry's character development would be significantly different. With his parents alive, he would be exposed to a more stable family environment. His magical education could start earlier and be more comprehensive as he learns from two powerful wizards. This could make him more powerful and less impulsive. Instead of seeking validation from others like he did at Hogwarts in the original story, he would have the unconditional love of his parents, which could shape him into a more well - rounded and less angst - ridden character. For example, he might not have had such a strong urge to prove himself in dangerous situations.
Well, it would probably strengthen his relationship with his friends. His friends would be happy for him to have his parents back, and it could lead to more group activities like family - style outings. For instance, they might all go on picnics together with Harry's parents.
Obviously, James and Lily Potter are the main characters as the title implies. Their return is the central event. Harry Potter is also a key character as their return would greatly impact his life.
Harry would likely be more confident. With his parents alive, he would grow up with their love and support, not having to face the same insecurities. He might be less impulsive as he would have their guidance. For example, he wouldn't have to jump into dangerous situations alone as he'd have his parents to back him up.
Meeting his parents would likely give Harry a sense of closure. He's always had this longing to know them, and actually interacting with them could fill that emotional void. This new - found peace might make him more confident in his actions, less driven by anger towards Voldemort.
One possible plotline could be that James and Lily return and have to deal with the changed wizarding world. They might be shocked at how much Voldemort's actions have affected society even after his defeat. Another could be that they return to help Harry face new threats that are emerging from the shadows of the old war.
If Lily and James survived, Harry would grow up with a very different sense of security. He wouldn't have the same orphan - like feelings and the need to prove himself as much. He might be more confident and less reckless in his actions. His relationship with his parents would shape him into a more well - rounded wizard, as he'd have their guidance and love from the start.
Well, it would change a lot. Harry would grow up without his father's influence, which could make him even more of an outcast in the Dursley household. Without James' presence in his life, Harry might not have the same sense of self - worth that he got from knowing his father was a brave Gryffindor. Also, the relationship between Harry and his mother Lily would be very different. Since she made James forget Harry, there must be some underlying reasons that could affect how Harry views his mother.
One possible plotline could be that Lily and James return during the time of Harry's battle with Voldemort. Their return could give Harry new strength and hope. They might use their old magical knowledge and skills to help in the fight. Maybe they could also reunite with their old friends like Sirius and Remus, and together they form a powerful force against the Dark Lord.
