Hermione Granger might be another potential spouse. They've been through so much together. A drunken night could lead to them realizing their deeper feelings for each other in a very unexpected way. However, they would then have to deal with the consequences and how it affects their friendship and the whole wizarding community's perception of them.
Even Ginny Weasley could be the one. They already have a strong connection. A drunken marriage could be a sort of extreme situation that fast - forwards their relationship. But then they would have to work through the fact that it happened in such an unorthodox way, and how to make it into a proper, loving relationship.
It could be Luna Lovegood. She has a unique and whimsical personality. Maybe they got drunk at a celebration in the wizarding world and in a moment of drunken folly, they got married. Their relationship could be really interesting to explore, with Luna's eccentricities and Harry's more serious nature.
Lucy could be a potential spouse. They have a very close relationship in the original story. Maybe they got secretly married in a moment of intense emotion. It would be a big shock to their friends, but also a very interesting development as they already have such a strong bond.
Hinata would be a very likely choice. They had a connection in the original series, and in a fanfiction, it would make sense for them to be married. Hinata's gentle nature could contrast well with Naruto's more boisterous personality.
Dumbledore could step in. As the most powerful wizard in the wizarding world, he has a deep connection with Harry. He would likely use his vast network of contacts and his own magic to find Harry. Dumbledore would also be concerned about the implications of Harry being sold and would want to protect him from any potential harm.
Well, Luna Lovegood could be a great ally for Harry. She has an open - minded and accepting nature. She might see something special in Harry even though he's been abandoned and would offer him her unique brand of friendship and support. Dumbledore, if he's still around in the fanfiction, would also be a key ally. He has a lot of knowledge and power and would likely take an interest in Harry's situation, guiding him and protecting him. And then there's the Weasley family. They are known for their warmth and kindness. Even if Harry is abandoned, they might take him in and be his family, with Ron being his closest friend among them.
It could be Lydia. They have a long - standing relationship in the show, and a secret marriage between them would be quite a shock. Maybe they eloped in a moment of passion and are now trying to figure out how to break the news to their friends.
There could be a rival who is from a wealthy and well - connected fashion family. They have all the resources and connections but lack Harry's raw creativity. So, they view Harry as someone they need to squash to maintain their family's dominance in the fashion world. This rival might use their family's influence to get better show venues or exclusive fabric deals, leaving Harry at a disadvantage.
The obvious enemies could be the Ministry of Magic. If Harry is stealing things, even if for good reasons, they would see him as a criminal. The Aurors would be sent after him. Another potential enemy could be some of the dark wizards who might want the same items that Harry is after. They would not want Harry to get in their way and would try to stop him or even capture him to get information on the whereabouts of the valuable items.
In some fanfictions, his secret spouse could be an original character created by the author. This character might be a fellow wizard or witch who has a special connection with Snape, perhaps they met during his early years at Hogwarts or in some other part of the wizarding world. They could share a common interest in potions or some other magical art, which brought them closer.
Obviously, the drunk dragon itself can be the main character. It could have a unique personality, perhaps being a bit clumsy and overly friendly when drunk.
Another possibility is that the heiress could be a new character entirely, created by the fanfiction author. She could be from a foreign wizarding family that has a claim to something in the British wizarding world. This new character could bring in different cultural elements of magic and challenge the traditional ways of the Hogwarts - centered wizarding society.
