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.
Hermione Granger is often a popular character. She can use her intelligence to figure out the implications of time travel and help Harry or deal with Tom Riddle in some way. For instance, she might research spells to counteract any dark magic that Riddle tries to use during their time - traveling encounters.
They can interact as students. For example, if they time - travel to when Tom Riddle was at Hogwarts, they could be in the same classes or clubs. Maybe they join the Duelling Club where Tom Riddle was known to participate. Another way is through chance encounters in the hallways or the library. They could strike up conversations about magic or Hogwarts history.
The theme of self - discovery is also quite common. The time - traveler often discovers things about themselves, their own magic, and their place in the wizarding world while interacting with Tom Riddle. They might learn about their own family history or the true nature of their magic through the experiences in the past. This can be intertwined with the moral dilemma of whether to interfere with Tom Riddle's life or not, as it could have far - reaching consequences for the future.
In some fanfictions, there could be a time - loop situation. Harry and Tom Riddle keep repeating a certain period of time, and each time they interact, they learn something new about each other. For example, they might start off as enemies but gradually come to understand the reasons behind each other's actions as they repeat the time period over and over again.
The exploration of their relationship is also a major theme. In many fanfictions, Harry tries to understand Tom Riddle, and they develop a complex bond that may range from enmity to a strange kind of understanding. For example, in some stories, they might start to see each other's points of view, which changes their relationship dynamics. This is especially interesting considering their roles in the original series. They are enemies, but time - travel gives an opportunity to rewrite that narrative in a way.
