Love is a very common theme. Their relationship, whether it's a budding romance or a deep platonic love, is often explored. Another theme is the idea of sacrifice. Given the complex situations they are often in, one or both may have to sacrifice something for the other.
Power dynamics also play a role. Elijah usually has a certain amount of power and influence, and how Elena relates to that, whether she challenges it or is protected by it, is frequently part of the story. Also, family loyalty. Since they both come from complex family backgrounds, how their relationship affects or is affected by their family loyalties is often a theme.
One more common theme is redemption. Elijah may be seeking redemption for past actions, and Elena can be a factor in that journey. Their journey together in the face of danger and the unknown is also a theme that many fanfictions explore, as they navigate through the challenges of their fictional world side by side.
Another theme is loyalty and betrayal. Given their complex relationships and the world they live in, there are often situations where loyalty is tested. For example, Elijah's loyalty to Klaus might be put to the test because of his feelings for Elena. And vice versa, Klaus might feel betrayed if Elijah gets too close to Elena.
One common theme is the protection of the baby. Given their supernatural world, there are always threats, and Elena and Elijah have to use their powers and wits to keep the baby safe. For example, in many stories, they face off against other vampires or witches who might want to harm the baby.
Another common theme could be the emotional journey of Elena during the pregnancy. She may have fears, hopes, and dreams for the future with Elijah and the baby. The story could explore how their relationship evolves during this special time, with both characters growing and changing as they prepare for parenthood.
Well, first of all, Elijah would be by Elena's side all the time. He would help her with her daily needs, like getting things she needs or helping her move around when she becomes less mobile during the pregnancy. He would also share his knowledge of the supernatural world with her, so she can better understand what might be happening to her and the baby, and together they can prepare for any challenges that might come their way.
Another possible reason is the need for comfort. Elena has been through a lot in the supernatural world. Elijah, with his calm and collected demeanor, could offer her a sense of safety. A kiss might be a way for them to find solace in each other, especially in a fanfiction where emotions are heightened and the characters are constantly dealing with life - threatening situations.
I really like 'Elena and Elijah's Uncharted Journey'. This fanfic takes them on an adventure outside of Mystic Falls. It has a lot of great dialogue that makes their connection seem very real and deep. The author does a wonderful job of building the story around their relationship.
One common theme is mentorship. Elijah often takes on the role of guiding Harry, using his knowledge and experience. Another theme is the exploration of different magical worlds. Since they come from different magical backgrounds, fanfics like to explore how their worlds interact.
One common plotline is how they deal with the reactions of their families and friends. Since their relationship might be unexpected, it can create a lot of drama. For example, Elena's friends from her original circle might be skeptical or even hostile at first.
There's also 'Elena's Choice: Elijah or Else' which explores the idea of Elena having to make a difficult decision between Elijah and other aspects of her life. The story is filled with tension and drama.
A fanfiction could explore the idea that Elijah's desire for Elena is part of a bigger prophecy. Maybe there's a hidden message that says if Elijah and Elena are together, it will bring peace to the vampire and human world. So he's driven by this sense of duty as well as his personal feelings for her. This would lead to a lot of internal conflict for Elijah as he tries to balance his feelings with the potential consequences of their relationship.
