Harry's reaction could be complex. Initially, he might be in disbelief and think it's some sort of trick or illusion. But once he realizes it's really them, he would be overcome with emotion. He could be a bit shy at first, not knowing how to act around them. But as time goes on, he would become more comfortable and start to bond with them, sharing his experiences in his own dimension and learning about theirs.
Well, it could be that Harry meets his parents in a special magical realm created just for them to reunite. His parents could show him some long - lost family magic that only their bloodline can use.

Obviously, baby Harry is one of the most important characters. He is the center of the story as he is the one having the encounter with his parents. And of course, his parents, James and Lily Potter.

In this fanfiction, Harry's encounter with his parents could be a very cathartic experience. He has been through so much pain and loss in his life. When he meets his parents, they would comfort him.
