Since houses play a major role in a student's identity at Hogwarts, for Harry, Draco and Blaise being triplets would mean redefining that identity. In Gryffindor, Harry has always been the hero figure, but with his Slytherin brothers, he might face some pushback from his housemates who are suspicious of the Slytherin connection. Draco in Slytherin would also have to deal with his own housemates' reactions. And Blaise, regardless of his house, would be in the middle of this complex situation. Their journey as triplets would be about finding a balance between their house identities and their family bond.
The relationship between Harry and Draco would change drastically. Instead of being rivals, they would have to come to terms with being brothers. There would be a lot of initial tension as Draco's Slytherin upbringing clashes with Harry's Gryffindor values, but eventually they might learn from each other. Hermione, being part of the triplets, would act as a mediator between them.
Their relationship could change Hogwarts in many ways. For one, they might form an alliance against common enemies within the school, like bullies or those who promote pure - blood supremacy too aggressively. This could lead to a more united front among the students. Also, their friendship (if it develops) could influence house rivalries. Gryffindor and Slytherin might not be as divided as before. Students might start to see that there are good people in both houses and that family bonds can transcend house differences.
They could form a sort of alliance. Harry, being the hero figure, could bring Draco into his circle of friends more often. Draco, with his Slytherin knowledge and connections, could help Harry in understanding some of the more mysterious aspects of Hogwarts, like the secrets of the Slytherin common room. Their relationship could bridge the gap between Gryffindor and Slytherin, changing the whole dynamic of the houses at Hogwarts.
In fanfiction, anything can be possible. Writers might rewrite the backstories of the characters. Maybe they could create a scenario where some powerful magic was involved at their birth that made them triplets despite their different families in the original story. For example, a dark wizard could have experimented with a spell that merged three different pregnancies into one, creating the situation where Hermione, Draco and Blaise are triplets.
In Hogwarts, it would be a wild change. Draco would be super conflicted. He's been taught to look down on Gryffindors and half - bloods like Harry. But with Harry as his brother, he'd have this internal struggle. Harry would probably be more open to Draco than Draco is to him. Harry would hope to convert Draco to a more accepting way of thinking. There would be times when Draco would be mean to Harry in public to keep up appearances, but in private, he might start to question his own beliefs because of their relationship.
A frequent plotline involves their family drama. With Hermione being a Muggle - born and Draco and Blaise from pure - blood families, there would be a lot of family issues to deal with. For example, how would the Malfoy family react to having a Muggle - born as part of their family? Also, they might be forced to work together to protect their family from threats. Maybe an old enemy of the Malfoy family targets them because of their new family situation. There could also be a plotline where they explore their magical abilities together and discover new and unique forms of magic due to their special connection as triplets.
Well, it could be a really interesting story. Maybe they would have to deal with the fact that they are triplets while also being in different houses at Hogwarts. Harry in Gryffindor, Hermione in Gryffindor too, and Draco in Slytherin. There would be a lot of conflict and also some unexpected bonding as they discover their shared origin.
It could make Draco feel exposed and vulnerable at first. But if Hogwarts uses the knowledge from his memories to help him, Draco might develop a newfound respect and loyalty towards Hogwarts. He could see it as an entity that truly cares about him rather than just a place of learning.
The story would be drastically different. Without Harry, there's no Boy - Who - Lived to be the main antagonist to Voldemort. Hogwarts might not be the safe haven it was in the original series. Voldemort could target the school more directly, and the students would live in constant fear.
Perhaps they were separated at birth due to some dark wizard's plot. As they grow up, they start to notice strange similarities in their magical abilities and instincts. When they find out they are triplets, they join forces to uncover the mystery behind their separation. They might face many obstacles, like opposition from their respective families who have different beliefs and values. Harry's Gryffindor - like courage, Draco's Slytherin cunning, and Blaise's own unique traits would all play a part in this adventure.
