I'm re-watching Dragons: Defender's of Berk on episode 13 Scouldy. Hiccup is discussing the dragon classes he teaches with the twins while trying to encourage and help Ruffnut to train the scouldren. It reminded me of some moments in Race to the Edge when the twins talked about the different people who tried to instruct them over the years. (Example: The wedding axe episode, when Toughnutt failed to complete the Mariage Officiation course) I just had the thought that Hiccup is probably one the few, if not only, teacher that never gave up on them. He always valued the twins and all the riders for their unique qualities. Hiccup is a wonderful person and a great leader.
