It could be that Merlin had a natural curiosity and spent a lot of time self-studying to acquire the ability to read. Or perhaps he had a magical encounter that unlocked this skill for him.
Maybe in the fanfic, Merlin was taught by a wise mentor or discovered some ancient scrolls that sparked his interest in learning to read.
Maybe it's a unique plot twist the author came up with to add some drama and challenges for Merlin.
Merlin could influence Harry to be more empathetic. Merlin, having witnessed the rise and fall of many, would understand the importance of seeing things from different perspectives. So Harry, under Merlin's tutelage, may start to look at the motives of his enemies and not just see them as pure evil. This could make Harry a more complex and well - rounded character, as he tries to find solutions that don't always involve combat but rather understanding and negotiation.
If Merlin has new powers or abilities in the official story that were not in the fanfiction before, it can break the fanfiction. For example, if in the original fanfiction Merlin was just a simple wizard but in the new official story he becomes an all - powerful being with god - like powers.
If Merlin forgets, it can create a lot of suspense. The other characters might not immediately realize what has happened, and they'll be confused by Merlin's changed behavior. This can lead to misunderstandings and tension within the group. For instance, if Merlin forgets his magical abilities, he might accidentally expose his powers in dangerous situations because he no longer has the knowledge to control them properly.
These fanfictions often explore themes of acceptance and love in a different context. They can help fans to better understand the characters on a deeper emotional level. For example, seeing how Merlin navigates his identity as a gay man in a world full of magic and political intrigue gives a fresh perspective on his character.
The fanfic can explore Merlin's sadness and confusion. He might wonder what he did wrong, and this could lead to self - reflection. Arthur, on the other hand, could experience a range of emotions from shame to fear of losing Merlin's friendship and support. These emotions can be shown through their dialogues, inner thoughts, and actions towards each other.
Merlin could be heartbroken. He might retreat into himself and become more withdrawn. After all, he has a deep bond with Arthur, and this sudden break - up would be a huge shock.
Merlin would be very worried. He would probably stay by Arthur's side day and night, using his magic secretly to try and heal him. He might also search for rare herbs or magical items that could cure Arthur.
He could become a Dark Lord due to betrayal. If someone he trusted deeply, like Arthur perhaps, turned on him because of his magic, it might push him over the edge.
Merlin is usually very empathetic. He'll listen to the reader's problems without judgment. In some fanfictions, he might share his own secrets and fears to make the reader feel less alone. He'll also do practical things, like bringing the reader food or making sure they have a warm place to stay if they're in a difficult situation. He'll try to show the reader that there are always options and that life is worth living.
