Bonnie could be a great addition. She's Elena's best friend, and her magic could play a role in the fanfic. Maybe she helps Alaric and Elena when they are facing a powerful enemy. Also, her friendship with Elena can add depth to the story.
They would likely become closer. The shared experience of having a child on the way would create a strong bond between them. Alaric would probably be very protective of Elena.
Perhaps a fanfic where Alaric, after his many experiences, decides to train Elena in some unique combat and survival skills. This could lead to a strong bond between them as they spend time together training and sharing their stories.
One great 'Alaric and Elena fanfiction' is 'A New Bond'. It delves into a different kind of friendship between them. Another one could be 'Alaric's Guidance for Elena' which shows Alaric as a mentor figure to Elena in a unique way. There's also 'The Unseen Moments' that focuses on their interactions that were not shown in the original series.
One common theme is the exploration of their relationship. Since they have a complex dynamic, fanfictions often focus on how they come to terms with their feelings for each other.
The relationship between Alaric and Elena in fanfiction is appealing because it allows for new storylines. In the original show, their interactions were somewhat limited, but in fanfiction, authors can explore different aspects like a deeper friendship or a mentorship that goes beyond what was shown.
One possible plot twist could be that the pregnancy is not what it seems at first. Maybe it's a magical or supernatural occurrence rather than a normal one. For example, it could be part of a spell gone wrong.
