How does Merlin impact the relationship between Arthur and Gwen in fanfiction?

Fanfiction often explores their relationship in many ways. For example, it can show how Merlin acts as a mediator between Arthur and Gwen. He might use his magic subtly to bring them closer or resolve misunderstandings. Sometimes, it shows how Arthur's sense of duty as king affects his relationship with Gwen, and how Merlin helps him balance that with his personal feelings.

Merlin might become even more protective of Arthur. Since Gwen is carrying Arthur's child, Merlin would see it as his duty to safeguard the future of Camelot. He could be more involved in Arthur's personal affairs, which might initially annoy Arthur but eventually he'd come to appreciate Merlin's concern.

It would become much more complex. They might start off being confused and a bit awkward around each other. But then, as they start to explore their feelings, they could become closer in a more intimate way. Their friendship would be transformed into something deeper, with a new level of understanding and trust.

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.

In the fanfiction, their relationship may develop gradually over a series of events. At first, they might have a bit of a rocky start, with Arthur being a bit oblivious to Merlin's true worth. But as they face challenges like political intrigue in the court, battles against dark magic, and helping the common people, they start to understand each other on a much deeper level. Merlin's selfless acts of using his magic for Arthur and the kingdom, and Arthur's growing respect for Merlin's abilities and character, all contribute to a relationship that blossoms into love. And this love is what leads Arthur to consider proposing to Merlin.

During the time of Merlin's captivity, they could have long conversations that they never had before. Arthur might open up about his insecurities regarding magic and his kingdom, and Merlin could share his true feelings about serving Arthur. This would strengthen their bond in a new and unexpected way.

It could start with a slow realization of their feelings. Maybe they were friends for a long time and then suddenly, one day, they look at each other in a new light. After getting married, they become more protective of each other. Arthur might become more open to Merlin's magic, and Merlin would be more involved in Arthur's political decisions.

In many of these fanfictions, their relationship becomes stronger. Arthur knowing about Merlin's magic means they can be more open with each other. For example, in some stories, they start to rely on Merlin's magic more in battles, and this deepens their trust.

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.

Merlin might be initially shocked and heartbroken. He has been so close to Arthur, and this sudden forgetfulness would be a huge blow to him.
