A witch could be an interesting match. Given Elijah's world of vampires, a witch spouse could bring in a whole new dynamic. The witch could use magic to help protect Elijah and their relationship from other threats in the supernatural world. They could also have a power struggle at times, which would add spice to the relationship.
A human with a strong will and a good heart could also be a great match. The human's innocence and different perspective on life could be a refreshing change for Elijah. They could teach him about the simple joys of life, while he protects them from the dangers of his world.
Her spouse could be a nature spirit. Since Artemis is closely associated with nature, a nature spirit would be a fitting partner. They could understand her love for the forest and all living things.
Apollo could marry Artemis' handmaiden. Since he often crosses paths with Artemis and her group, he might fall for one of the gentle and nature - loving handmaidens. This would be an interesting choice as it would also create a connection between Apollo and Artemis in a new way.
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.
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.
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.
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.
It could also focus on their personal growth within the marriage. Bella might have always been a bit shy and Elijah helps her come out of her shell. He encourages her to pursue her dreams, like starting her own small business. In turn, Bella helps Elijah become more in touch with his emotions and they both become better versions of themselves through their relationship.
It could be a reformed villain. Maybe someone like Grant Ward who had a complex relationship with Skye. If he had somehow redeemed himself off - screen and they fell in love, Skye would have to keep it a secret because of Ward's past actions against S.H.I.E.L.D.
The main characters are clearly Elijah and Bella. Since they are married in this fanfiction, they are likely at the center of the story, with their relationship being the main focus.
Rebekah could also be an option in a different take on the fanfiction. Their long - standing relationship as siblings could be transformed into a romantic one in a unique way. Rebekah has always cared deeply for Elijah, and this new aspect of their relationship could be explored during the pregnancy. It would add a layer of complexity and taboo to the story.
