Sure. There are some really creative ones. For example, a fanfic could be about a female character who has a special connection with Tyler. She might be a witch and they team up to fight against common enemies in their town. These fanfics often explore different relationships and scenarios that weren't fully shown in the original story.
One common theme is adventure. Since the original story has a lot of elements of exploring haunted places and fighting ghosts, fanfics often continue this adventure - filled spirit.
A must - read is 'Love Against All Odds'. Here, the OC is a human who gets involved with Tyler during all the supernatural chaos in Mystic Falls. It's a slow - burn romance that is full of heartwarming moments. The author does a great job of showing how the OC adapts to the dangerous world around her while falling for Tyler.
Well, a common trope is the 'found family'. Since Lockwood, Lucy and George are sort of a makeshift family already, in fanfiction this can be expanded. They might take in a stray agent or someone in need and make them part of their family. The 'power - up' trope is also popular. For instance, Lucy discovers a new way to enhance her Talent and becomes even more powerful in dealing with ghosts. Then there's the 'mystery within a mystery' trope. They solve a ghost - related mystery that leads to an even bigger mystery about the history of the ghost - hunting world.
A fanfic that stands out is 'Tyler Lockwood's New Beginning'. It begins after a major event in the show and imagines Tyler starting over. It has some great character interactions, especially with characters that he didn't have as much time with in the original series. It also has a really engaging plot that keeps you reading.
One common theme is the confession of hidden feelings. Usually, the kiss is a result of one or both of them finally admitting their deep - seated emotions for each other. Another theme could be the moment of victory or survival. After facing a particularly dangerous supernatural encounter, they might share a passionate kiss as a celebration of still being alive.
