Well, it could start with a sense of mystery. Hiccup might notice a figure in the distance that seems to be watching him. As he approaches, he realizes it's his mother. There would be a slow - building tension. His heart would start to race. When they are finally face - to - face, it could be a quiet moment, with only the wind blowing gently. Hiccup might stutter out a greeting, and his mother would reach out to touch his face, a single tear rolling down her cheek.
The emotional journey could be one of shock and joy. Hiccup has grown up without his mother, so when they meet, he'd likely be stunned at first. Then, overwhelming happiness would set in as he finally gets to know the woman who gave birth to him. There would also be a sense of longing fulfilled, and he might feel a newfound connection to his family heritage.
Hiccup was taken by his mother in the fanfiction when she realized he was in grave peril. She acted quickly and without hesitation to ensure his safety.
Hiccup's friends would be extremely worried. Astrid, being Hiccup's closest friend and love interest, would probably be the first to take action. She would gather the other riders and start planning a rescue mission right away. Snotlout might initially be a bit hesitant, but the thought of losing Hiccup would push him to join in. Fishlegs would use his knowledge of dragons to figure out where Drago might be hiding Hiccup.
Maybe Hiccup's mother is put in a difficult position where she has to make a choice that seems like a betrayal to Hiccup. Or perhaps she's under some kind of spell or mind control.
His character could also develop in terms of his understanding of different kinds of magic. He starts off knowing only about the magic related to dragons. But in the fanfiction, as he watches and interacts with the Guardians, he begins to understand their magic. This could lead to him becoming more open - minded and adaptable. He might start to think about how the different magics could work together to protect both his world and the world of the Guardians. And this new knowledge could also change how he approaches problems back in Berk. For instance, he could try to incorporate some of the Guardians' ideas or magic - like things into his dragon - training methods.
Astrid is an obvious choice. She already has a close relationship with Hiccup in the original story. Then there could be Ruffnut and Tuffnut's sister, who might see Hiccup in a new light and be attracted to his growing confidence. Also, some new characters from unexplored Viking tribes could be part of it. Maybe a healer from a far - off land who is intrigued by Hiccup's connection with dragons.
If Hiccup is under Pitch Black's control, it would be a huge shift in his relationship with Toothless. Normally, they have a deep, trusting bond. But now, Hiccup might start to command Toothless in a harsh and uncharacteristic way. Toothless would sense that something is wrong with his rider. He would try to resist Hiccup's commands at times, which would create conflict between them. Eventually, Toothless might be the key to breaking Pitch Black's control over Hiccup as he tries to reach the real Hiccup within.
Well, he might be initially shocked. He could stand there for a moment, his eyes wide open, trying to process the news. Then, he would probably break into a big smile and hug Astrid tightly, whispering words of joy and excitement.
Their relationship might start with curiosity. Hiccup would be curious about Elsa's ice powers and Elsa about Hiccup's connection to dragons. As they interact more, they start to respect each other's abilities and personalities. This mutual respect turns into friendship, and then gradually into love. The news of the baby would strengthen their bond as they now have a shared future to look forward to. They would support each other more, with Hiccup protecting Elsa during her pregnancy and Elsa using her powers to help Hiccup in his adventures.
