At first, he may be in disbelief. But as he starts to understand what he's seeing, he could become solemn. He realizes the weight of the future and the responsibility he may have to shape it in a positive way. He might also feel a bit of fear, especially if he sees the loss of his friends or loved ones. But overall, his Gryffindor courage would likely kick in, and he'd start to think about how to face whatever the future holds.
He might be shocked at first. Just imagine seeing things that haven't happened yet. It's quite a mind - blowing experience.
He could be shocked at the brutality. Maybe he'll be stunned into silence at first, just taking in all the chaos and destruction.
He may laugh out loud at the funny parts. Some fanfictions are full of humorous situations and dialogues that can really tickle his funny bone.
Harry might be a bit skeptical at first. He would question whether this is really his future self or some kind of trick. But as the future self starts to share some personal details or knowledge only Harry would know, he would start to believe. Then, he could become eager to learn from his future self, asking all kinds of questions about his future, his friends, and his role in the wizarding world.
He is probably very surprised at first. After all, coming from the wizarding world, being knighted by the Muggle Queen is quite unexpected.
He could be shocked at first. Imagine finding out that your whole life has been based on half - truths. He might need some time alone to process it all.
In fanfiction, Harry could react in various ways. He might be curious about this new place. He'd start exploring, looking at all the strange buildings and people. But he'd also be cautious because he doesn't know if there are any threats. He might also try to find other wizards or witches, thinking that there could be some kind of hidden magical community in Vegas. As he explores more, he'd gradually get used to the muggle environment while still trying to figure out how to get back to his normal life in the wizarding world.
Well, Howard Stark might have a range of reactions. He could be in awe of the advancements, or he might feel a bit left behind. Maybe he'd also have some fatherly pride and a desire to have been more involved.
It could be a very creative and interesting concept. Maybe it represents the idea of the magical world of Hogwarts being an observer or a kind of inspiration for the fan - created stories in Harry Potter fanfiction. It might imply that the essence of Hogwarts, its characters, and its magic are so strong that they seem to 'watch over' the various interpretations and stories written by fans.
Some might be in shock. After all, Harry has been such an important figure in the wizarding world for so long. His friends like Hermione and Ron would probably be very worried about him and try to find out where he went. The Ministry of Magic could be in a panic, fearing that without Harry, they'll be vulnerable to new threats.
