Their friends are likely overjoyed at first. Fishlegs might be a bit of a nervous wreck, constantly worrying about Astrid's health and the well - being of the baby. He'd probably be reading every book he can find on dragon - rider pregnancies (if that's a thing in their world). Snotlout would probably make a bunch of inappropriate jokes at first, but deep down he's also excited. Ruffnut and Tuffnut would be their usual chaotic selves, but also show their support in their own unique ways, like bringing strange gifts they think the baby would like.
Some of their friends could be a bit skeptical at first. They might worry about how having a baby will change Hiccup and Astrid's roles as dragon - riders. However, as the pregnancy progresses, they would come around. They would start to plan all sorts of things for the baby. They might start making baby clothes out of dragon - proof materials or start training baby - friendly dragons for when the child is old enough to ride. Their friends' reactions would evolve from initial concern to full - blown excitement and support.
The friends would react with a mixture of excitement and protectiveness. For example, Toothless, being Hiccup's closest companion, would be extra vigilant. He might stay closer to Astrid than usual, as if guarding her and the unborn child. The other dragon - riders would offer practical help too. They could help build a new, bigger and safer dwelling for Hiccup and Astrid in anticipation of the new arrival. And they'd all be there to listen to Astrid's pregnancy woes and offer advice based on their own experiences.
Astrid might initially be in shock. She could just stand there, frozen, unable to believe that Hiccup is really gone. Her eyes wide open and her body trembling as she tries to process what has just happened.
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.
Hiccup would probably be very worried. He'd rush to her side immediately. He might start to check her injuries right away and call for help if needed.
One possible fanfiction could be about how Hiccup and Astrid deal with the pregnancy. Hiccup might be overprotective, constantly worried about Astrid and the baby. Meanwhile, Astrid could be trying to keep up with her normal Viking duties while also preparing for motherhood. And the lemon element could be a symbol in the story, perhaps it's something Astrid craves during her pregnancy, leading to some humorous or heartwarming scenes between her and Hiccup as he tries to find the perfect lemon for her.
During the pregnancy, their relationship would shift to be more centered around the upcoming baby. Hiccup would be constantly thinking about how to keep Astrid and the baby safe, especially with his role as a leader. Astrid would be dealing with the physical and emotional changes of pregnancy, and Hiccup would be her main support. This would bring out new aspects of their love for each other, like a deeper level of understanding and patience.
One possibility could be that they face challenges in protecting their unborn child from the threats in their dragon - filled world. For example, they might need to find a safer place to raise the baby, away from the more dangerous dragons or villains. Maybe they also struggle with how to balance their duties as dragon riders with the upcoming responsibilities of parenthood.
There would be a shift in their dynamic as they prepare for a family. Hiccup, who is used to being adventurous, would have to focus more on home and stability. Astrid, while still strong - willed, would become more nurturing. They would need to find a new balance in their relationship, between their old selves and their new roles as parents - to - be.
Hiccup might be very resistant at first. He's always been an independent thinker, so being forced into a marriage would go against his nature. He could try to find ways to escape the situation, like running away or finding loopholes in the marriage contract. But as he spends more time with Astrid, he might start to see her in a different light and become more accepting of the situation.
One friend might be a bit jealous at first, secretly wishing they were in Eve and Roarke's position. But overall, most of their friends would be very supportive. They would gather around, offer to help with things like setting up the nursery, and share their own experiences of pregnancy and parenting if they have any. There could also be a friend who is a bit of a worrywart and is constantly giving Eve advice on what she should and shouldn't do during the pregnancy.
Some friends might be shocked at first. Kurt could be overly dramatic, worrying about how this will change everything. Finn might be a bit jealous or concerned for Rachel. Quinn could have a complex reaction, since she has her own history with Puck. But overall, most of their friends would probably come around and offer support, like helping with baby preparations or just being there to listen.
