A plot that often shows up is the idea of soulmates. In fanfiction, Merlin and Morgana could be fated to be together as soulmates. Their love is written as something that is destined, and no matter how much the world tries to keep them apart, they keep being drawn back to each other. Another interesting plot is that Morgana has a premonition of their love and future together, and this changes her attitude towards Merlin from the start. She then tries to find ways to make their relationship work despite all the odds in Camelot. And there are also fanfictions where they meet in secret and have a secret relationship, with all the tension and excitement that comes with hiding their love from the people around them.
A plot where Morgana follows Merlin to Avalon. In this, she discovers a whole new world and Merlin's connection to it. It's really exciting as it reveals a lot about the magical lore of the series.
Yes, there are quite a few. Some explore alternative power dynamics between Morgana and Merlin within the fanfiction realm. You can find them on various fanfiction websites like Archive of Our Own.
The child could be a bridge between the two opposing sides that Merlin and Morgana represent. The child's innocence and unique perspective could start to change the views of those around them, leading to a possible reconciliation between Merlin's side and Morgana's followers. This would involve a lot of character development for the child as well as for Merlin and Morgana as they see the world through the eyes of their offspring.
A plot twist might be that the baby has some sort of prophetic power even before it's born. This power could show visions to Morgana or Merlin about the future of Camelot. It could also be that the pregnancy is part of a grander magical plan set in motion centuries ago by an ancient sorcerer, and Merlin and Morgana are just pawns in this plan, not realizing the true significance of the pregnancy until later events unfold.
One plot idea could be Merlin reveals a long - hidden prophecy to Morgana that involves her true destiny. Another could be Merlin tells Morgana about a secret magical realm that only he knows of, and they embark on a journey to explore it. Or perhaps Merlin tells Morgana about his own insecurities and fears regarding his magic, which in turn makes Morgana open up about her own struggles.
One idea could be that Merlin teaches Morgana about the old magic in a secret grove. He shows her spells that can heal the land, and they bond over their shared connection to magic. Another could be Merlin teaching Morgana how to control her visions, which she's been struggling with. It could lead to a deeper understanding between them and a new alliance within Camelot.
Well, a cool plotline might be the conflict it creates within the wizarding world. Since Merlin and Morgana have such complex and often opposing legacies in the lore. Harry, as their heir, could be caught in the middle of different factions. One side might see him as a great hope for a new era of magic, while the other could view him as a threat to the existing power balance. Also, his relationship with the Ministry of Magic could change drastically as they try to either control or use his newfound connection to Merlin and Morgana.
One interesting plot twist could be that when Merlin and Morgana time travel, they end up swapping their magical abilities. So Merlin has Morgana's dark magic skills and vice versa. This creates a whole new dynamic as they struggle to adapt to these new powers in a different time period.
One idea could be that their kiss is a moment of realization. Maybe they've been enemies or at odds for a long time, and the kiss makes them see each other in a new light. For example, Morgana realizes that Merlin's magic isn't as bad as she thought and that he has been trying to protect Camelot all along. Another plot could involve a magical bond that forms through the kiss. This bond could give them shared powers or make them telepathically linked, leading to some really interesting interactions as they learn to deal with this new connection. A third idea is that the kiss is a secret pact. They kiss to seal a deal to work together against a greater evil that threatens Camelot, but they have to keep their new alliance a secret from everyone else in the kingdom.
One unique theme is the exploration of their relationship beyond the typical good - vs - evil dynamic. In some fanfics, they find common ground based on their shared experiences with magic, which is really interesting.
