Harry might initially be shocked and angry. He'd try to reason with Riddle, knowing that there must be some underlying reason for his kidnapping. He'd draw on his experiences and the values taught to him by his friends and mentors at Hogwarts to stay strong and not give in to Riddle's demands.
Harry would likely be defiant. He has faced Voldemort (Tom Riddle) before and he's not one to cower easily. So, he'd probably start looking for ways to escape right away, using his wits and any small magical items he might have on him.
Harry would probably be very defiant at first. He has faced Voldemort (Tom Riddle) before and he won't go down without a fight. He would likely try to use his magic skills to escape or at least hold Tom Riddle off until he can find a way out.
At the start, Ginny would be shocked and terrified when Tom Riddle kidnaps her. However, as time passes, her Gryffindor courage would kick in. She would start to analyze Tom Riddle's motives and actions. She might pretend to be more vulnerable than she actually is to lower his guard. Ginny could also try to communicate with any magical creatures or objects in her vicinity for help. And she would be mentally preparing herself for a fight or escape, using every bit of her magical training and her wits to outsmart Tom Riddle.
Hermione would probably be very cautious at first. She would be worried about the potential danger that Tom Riddle could pose, even as a child. But she might also see it as an opportunity to study the roots of dark magic and how to prevent someone from turning to the dark side.
Tom Riddle might be very suspicious at first. He is a very intelligent and cautious person. He would likely view time travelers as a threat to his plans or as a strange new phenomenon that he wants to control. So, he could start by trying to figure out their motives and how they managed to travel through time.
One possible plot twist could be that Tom Riddle discovers Harry has a hidden power that he didn't expect. Maybe Harry has the ability to resist Riddle's mind - control spells in a unique way. This could lead to a battle of wills between them where Harry tries to outwit Riddle while being held captive.
I think the story could take many turns. Harry, as Tom Riddle, might try to change the course of events he knows led to evil. Or he could be tempted by the power that Tom once craved. It would be a complex web of internal and external challenges.
Harry would likely use his own experiences of facing inner darkness. He could talk to Tom about his struggles with the part of Voldemort that was in him. By sharing his own story, he hopes to make Tom understand that he has a choice and doesn't have to give in to any dark desires.
Harry is known for his courage. So, when Tom Riddle kidnaps him, this courage would not let him give in easily. He would face Riddle head - on, not showing any fear, which might unnerve Riddle to some extent. Also, Harry is very loyal to his friends and the wizarding world. This loyalty would give him the strength to resist any offers or threats from Riddle. For example, if Riddle tries to persuade Harry to join the dark side, Harry's loyalty would make him firmly reject such an idea.
At first, it might be rocky. Tom would be suspicious of Harry's intentions. But as Harry shows him genuine care, Tom would start to open up. Eventually, they could become like family, with Tom looking up to Harry as a role model.
His character would likely be more calculating and less trusting. Growing up with Riddle, Harry would be exposed to a world of manipulation and power - seeking. He might not value friendship as much as in the original story.
