I'm not very familiar with this specific fanfic. However, generally, a fanfic about Loki and Thor might explore their complex relationship in the context of the Marvel universe. If Loki is intersex in this fanfic, it could add an interesting layer to the character's identity and how they interact with Thor.
His character could also develop in terms of his powers. Maybe the abandonment was related to his latent magical abilities. He could start exploring and mastering his powers more in the fanfic. Thor's presence could either be a hindrance or a help. If it's a help, Thor could encourage Loki to use his powers for good, which would be a big step in Loki's character development.
Once upon a time, there was a little bird named Inspirational Bird. Inspirational Bird loved chocolate and ate a lot of chocolate every day. One day, the inspirational bird found that its tail was getting shorter and shorter. It was very worried. The inspirational bird decided to go to its doctor, hoping that the doctor could help it solve this problem.
Inspirational Bird went to the doctor and the doctor examined Inspirational Bird's tail and said,"Inspirational Bird, you ate too much chocolate and your tail hurt." You need to control your appetite and stop eating."
Inspirational Bird was very sad when he heard the news. It thought,"What if I can't keep eating chocolate?"
Therefore, the inspirational bird began to look for other things to distract it. It began to sing and dance and play with other birds. The inspirational bird soon discovered that even if it couldn't eat chocolate, it could still do many other things, and these activities made it very happy.
Inspirational Bird understood that even if there are some difficulties in life, as long as we can take a positive attitude to distract our attention, we can still be happy and overcome these difficulties.
From then on, the inspirational bird no longer worried about its tail because it knew that even if it could not control its appetite, it could still do something else to make itself happy.
Perhaps Loki is forced to stay in Jotunheim. There could be a powerful spell or curse that binds him to the realm. This could lead to an interesting plot where Thor has to find a way to break the spell and rescue Loki. It would also give Loki a chance to explore his identity while being stuck there.
One common theme could be redemption. After experiencing abuse, Loki might be on a journey to redeem himself or find a way to heal. Another theme could be power dynamics. The abuse might be related to power imbalances between Loki and Thor, which can be explored in different ways. And also, the theme of forgiveness could play a role, either Loki seeking forgiveness from Thor or vice versa.
Well, it can be a way to bring more diversity to the fanfic world. It allows fans to explore different aspects of Loki's character that might not be explored in the official Marvel stories.
Loki is not typically shown as gay in the main comic continuity. But comics are diverse, and there might be rare instances or special editions where his sexuality is portrayed differently.
