Not like, not serious, but not all serious, if you get me. Like, there’s a super fast paced preparation for war kinda scene, and Hiccup’s defering to the bae/second in command and they’re speaking as fast as they can, then….
Hiccup: Have you secured the battlements?
Hiccup: Have you secured the elderly and children in the stables?
Hiccup: Will you marry me?
Astrid: Yes. Wait, what?
Hiccup: (running away) You-said-yes-no-takebacks!
