The druids would likely be very happy. Freya is one of them, and if she is in love with Merlin, it could mean a stronger connection between Merlin and the druid community. However, some of the more traditional Camelot knights might be skeptical. They are used to a certain order and the idea of Merlin, a sorcerer, being in love with a druid girl might seem a bit strange to them at first.
Merlin's relationship with Gaius would be interesting. Gaius might be worried about the potential dangers that come with Merlin's new relationship. He might fear that Freya's presence could draw unwanted attention to Merlin's magic. But as he sees how much Freya cares for Merlin, he might also start to accept their relationship and the kiss as a natural part of their growing connection.
Their relationship would likely become more protective. Merlin would be constantly worried about Freya and the baby's safety. He'd use his magic more discreetly to safeguard them from any potential threats.
If they kiss in fanfiction, it might make Loki jealous. Loki has always had a complex relationship with Thor, and seeing Thor getting closer to Valkyrie could stir up his envy. He might try to create some trouble between them.
She might be completely overjoyed. With tears of happiness in her eyes, she'd immediately say yes and throw her arms around Merlin. After all, she loves him deeply and has probably been waiting for this moment.
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.
C.C. might view it with a sense of detachment at first. But then she might realize that Lelouch is becoming more attached to Kallen in a way that could potentially change their own relationship. She might start to feel a bit left out or even jealous, as she has been by Lelouch's side for a long time and has her own unique bond with him.
Some characters might be supportive. For example, their closest friends who have seen their bond growing might be happy for them. However, others who are more focused on the mission and traditional values might be skeptical or even opposed. Their leaders could worry that their relationship might distract them from their duties in the Spirit Animals world.
If Poseidon and Athena kissed in a fanfiction, other gods would likely be shocked. For example, Zeus, being the king of the gods, might see it as a threat to the established order. He could try to separate them or punish them to maintain his control. Hera, who is often jealous and protective of her position, would also be likely to oppose their relationship.
Well, it could start with Merlin finding Freya in a difficult situation. Maybe she's being chased by some dark forces. Merlin uses his magic to save her and in that moment of relief and gratitude, they share a kiss. It could be a very tender and innocent kiss, filled with the start of new feelings between them.
Their relationship would become more intertwined with their daily lives. They would have to make decisions together, like where to live. Maybe they would choose a place that is in between their two magical worlds. Also, they would start to think about the future in a more long - term way, such as planning to have children and how to raise them with both of their magical heritages.
Some superheroes might be shocked. For example, Captain America, who is more traditional, would be very surprised and might question their motives. He would worry about how this new relationship dynamic would affect the team's morale and unity.
