This is a ship that I've been thinking about for a long time, and the more I think about it, more I like.
There's practically nothing about them, and, when there's, it's always about Hiccup and him at the center. But I wanted to explore just Dagur and Viggo, I think they both have a lot of potential.
I have some fun ideas that I want to draw, and maybe do mini comics.
I always liked the idea of Viggo never had much experience with relationships, this is normally part of my headcanon of him being aroace, but here would be another reason. Because he was heir, then a chief and a very cold and distant person, people never tried to get close to him intimately because they were afraid.
Everyone except Dagur, because he has no idea of danger.
For me, Dagur is an open book. His emotions are so strong that it shows through him. And he always says what he thinks, without thinking about the consequences.
Think of a version where Viggo joins his brother earlier, or Dagur not leaving after freeing Heather.
I imagine Dagur constantly flirting with Viggo, because yes, he's a dick and annoying, but he's hot, you can't deny it. But Viggo is always ruthless and has no qualms about threatening him.
*after Viggo threateningly asks Dagur to leave for flirting with him again*
Ryker: Are you crazy? You have no idea of the danger, do you?
Dagur: It's not my fault if your brother doesn't know how to have fun
Viggo goes straight to his room, and there, alone, he becomes a complete emotional mess. Your face turns completely red and feels like it's going to burn.
Viggo doesn't like Dagur. He doesn't even feel attracted to him. But it's the first time someone has shown any interest in him, it's uncomfortable but exciting at the same time. He's never been through this before and he doesn't know how to deal with it.
After a while Dagur gives up flirting with Viggo. And, strangely instead of feeling relieved, Viggo misses the attention. And against all his code and morals, he goes to confront Dagur about this and their conversation turns to something else. A hint: it's sex
*after a hot and wild sex, Dagur is completely satisfied and happy. Viggo is also equally satisfied , but very angry*
Viggo: This doesn't mean anything okay? This will never happen again and if you talk about this to anyone I swear I'll make you wish for death.
