The 'alternate universe' trope is quite common. For example, an AU where they are not actors but in different professions, like one being a detective and the other a journalist, and they meet in the course of their work. Also, the 'enemies - to - lovers' trope can be found. Maybe their characters start off on the wrong foot, perhaps due to a misunderstanding, but eventually realize they have feelings for each other.
There's also the 'roommate' trope. Fans might write about them as roommates, which leads to all sorts of comical and romantic situations. This trope allows for a lot of close - quarters interaction and the development of a relationship. Additionally, the 'time - travel' trope can be used, where one or both of them travel through time and how that affects their relationship.
There are a lot of fanfic writers out there who are inspired by actors like Aidan Turner and Dean O'Gorman. You could try reaching out to some fanfic writing groups on social media platforms. Explain that you're interested in fanfics about these two actors. They might be able to point you in the right direction or even share some of their own works.
One common theme could be friendship. Given their on - screen chemistry, many fanfics might explore a deeper friendship between their characters. Another might be adventure, if they are in shows or movies that involve adventure elements.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often a great number of fanfics dedicated to various pairings and characters. Just search for their names on the site, and you'll be presented with a list of relevant stories. Another option could be Fanfiction.net, although AO3 generally has a more organized tagging system for finding specific types of fanfics.
The 'hurt/comfort' trope is also common. For example, if one of them gets injured or is in a difficult situation, the other comes to their rescue and they grow closer through that experience. It's a great way to show their connection. There are also fics that use the 'soulmate' trope, where they are somehow fated to be together, which can be really sweet and romantic.
Some fanfics about Aidan Turner might be set in a modern - day AU (Alternate Universe). In these, he could be a regular guy who just happens to look like Aidan Turner, and the story could revolve around him falling in love with an ordinary person. These types of fanfics often play with the idea of fame and normal life.
One common theme is adventure. Given his roles often involve some sort of journey or quest, fanfiction writers like to expand on that. For example, sending his characters on new and exciting adventures.
One popular trope is the 'hurt/comfort' scenario. For example, Dean gets injured on a hunt, and Cas takes care of him, which leads to a tender moment and a kiss. It plays on the emotional bond between them and the protectiveness they feel for each other.
One popular trope is the 'First Kiss' trope. It often builds up a lot of tension between Castiel and Dean before they finally share that first, passionate kiss. Another is the 'Forbidden Love' trope, as their relationship within the context of the show has many obstacles, and this is often explored in fanfiction with their kisses being something that goes against the norm or is kept secret.
The 'alternate universe' trope is quite common too. For example, there are fics where Dean and Castiel are in a modern - day high school setting instead of the supernatural world they're usually in. It gives a fresh take on their characters and relationship.
Sure. One popular Aidan Turner fanfiction is 'The Lost World of Aidan Turner' which takes his characters and places them in a whole new adventure setting. It has a great plot that really draws you in.
