Perhaps Tony sees value in the creativity and ideas expressed in Loki fanfiction. He might be protective because he understands how important these stories are for the fans who write and read them. It could also be that he has a special connection to Loki in the fanfiction universe and wants to ensure its integrity.
It could mean that Tony, in the context of fan - created stories about Loki, acts in a way to safeguard or be defensive about them. Maybe he doesn't want others to criticize or misinterpret the Loki fanfiction.
He might just be a big fan of Loki himself in the fanfiction world. So, he wants to protect the stories that feature Loki.
In the fanfiction, Loki may have developed a sense of respect or even friendship for Tony. They are both very intelligent characters. Loki might admire Tony's ingenuity and courage. So when he realizes that Tony is in danger in Siberia, his new - found feelings for Tony drive him to save his life. Also, Loki might be bored with his usual villainous ways and wants to do something good for a change, and saving Tony seems like a good start.
It could mean that the fanfiction is not favorable or positive towards a character named Tony. Maybe it portrays Tony in a negative light or goes against the typical 'friendly' interpretations of the character in fan - created stories.
Well, it might suggest that in certain fanfiction, Loki is given a backstory or a current situation that is more in tune with what a teenager might go through. For example, he could be a misfit in a new school (in a fan - created, fictional school setting related to the Loki universe), or he could be struggling with family relationships in a way that mirrors how a teenager might. Fanfiction writers might be using this concept to add a new layer of depth and relatability to the Loki character.
Well, perhaps in a particular context, the way Loki is presented is with a lot of creative liberties that are characteristic of fanfiction. For example, if there are new relationships or character traits given to Loki that are not in the mainstream official storylines. Fanfiction often takes existing characters and puts them in new and sometimes unexpected situations, and if Loki is being classified as such, it might be that he's being shown in a way that's more in line with that fan - created style of storytelling.
Maybe he uses his magic. Loki is a powerful sorcerer. He could have created a portal or used some sort of teleportation spell to get to Siberia quickly.
It could mean that Bill, perhaps a character or a person in the context related to the Harry Potter fandom, guards or looks out for Harry Potter fanfiction. Maybe he tries to prevent it from being misused, like protecting it from being plagiarized or from getting baseless negative criticism.
Being protective of Evie and Mal in fanfiction might mean that a character in the fan - created story looks out for their well - being. For example, they could defend them from villains or other characters who mean them harm. It could also mean that the author of the fanfiction is writing in a way that shows a special care for these two characters, perhaps by giving them more positive storylines or protecting them from any unfair or negative situations within the narrative.
It could also end with a more complex resolution. Loki realizes the error of his ways during the time he has Tony kidnapped. Maybe through their conversations, Loki sees the value in Tony's life and the good he does. So, Loki releases Tony and decides to help the Avengers in their fight against a common enemy as a form of redemption.
It could imply that in a fictional context, the Cloak of Levitation (assuming it's that cloak) has an affinity for fan - created stories about Tony Stark. Maybe it's a humorous or creative concept where the cloak is personified to have a 'liking' for this type of fanfiction.
