Oh my thank you so much !
Haha but yeah right ? Hiccup's so smart, curious, always taking notes, he fucking invented a way to ride dragons ! He made the "harness" (is that the right word ?)! He "repaired" Toothless' tail ! He learned how to act with creatures he had so little informations about, just by himself, because he took the time to observe them !
Really, how can people not put him in Ravenclaw after that ?
