If not resolved, it could lead to a breakdown in their relationship. Merlin's flinching might eventually push Arthur away, making him feel like Merlin doesn't trust him. This could cause Arthur to distance himself from Merlin, which would be a huge change from their usually close bond in most Merlin - Arthur stories.
It could also be due to some past trauma. Perhaps Merlin has been through an experience where Arthur was involved in a way that now makes him flinch. Like, Arthur might have accidentally hurt Merlin during a battle training in the past, and now Merlin flinches whenever Arthur makes a sudden move.
In many fanfictions, Merlin's magic acts as a catalyst. For example, if Freya is in danger, Merlin uses his magic to protect her. This shows Arthur that there is more to the world of magic than he thought. It can make Arthur more accepting of Freya, who is often associated with magic. Sometimes, Merlin's magic also reveals secrets about Freya that Arthur needs to know, which either brings them closer or causes some initial friction as Arthur has to adjust to new revelations.
In most cases, it initially causes shock and confusion for Arthur. He has grown up believing magic is evil, so seeing Merlin, his closest friend, using it is a huge blow. However, it can also lead to a deeper understanding between them. Arthur realizes that Merlin has been using his magic all this time to protect him and Camelot. This can strengthen their bond as Arthur now sees Merlin in a new light, not just as a servant but as a powerful ally.
In such a fanfiction scenario, the roughness can have various impacts. It could create a sense of tension and conflict in their relationship. Merlin might start to question Arthur's true feelings towards him. But on the other hand, this rough treatment could also be a sign of Arthur's internal struggles or misunderstandings. Maybe he's dealing with his own insecurities or pressures and taking it out on Merlin in the wrong way. As the story progresses, this could be a catalyst for character growth for both of them, with Merlin learning to stand up for himself and Arthur learning to be more empathetic.
It deepens their bond. It shows that Arthur values Merlin highly enough to give him such a personal item.
In fanfiction, their relationship often develops in more nuanced ways. For example, some stories focus on the trust that slowly builds between them. Merlin's magic might be revealed earlier, leading to a period of adjustment for Arthur, which in turn deepens their connection.
Well, the age difference can create a dynamic where Merlin is seen as the wiser one. Since he's older, he may have different values and beliefs formed over a longer time. This could lead to some clashes with Arthur, who might be more impulsive due to his younger age. But at the same time, it can also make their bond stronger as Merlin can offer Arthur a different perspective on things.
The age difference in this fanfiction can have a profound impact on their relationship. Merlin's youth could lead to him being more impulsive, which might initially annoy Arthur. However, it also means Merlin has a more open - minded view. Arthur, being older, has more experience and power, but Merlin's younger age gives him a certain charm and innocence. This contrast can lead to a relationship where they both balance each other out, with Merlin bringing spontaneity and Arthur bringing stability.
It completely changes the dynamic. Instead of just a friendship, it adds a layer of romantic love. Their interactions now have a different undertone. For example, a simple glance between them in the original story might just be friendly, but in the fanfiction, it could be filled with passion and love.
It could strengthen their relationship. If Merlin gains more power and knowledge from the tower, he can better protect Arthur. This might make Arthur trust Merlin even more, despite not knowing about his magic.
