I love how in the first movie, it’s finally the hardened Vikings acknowledging him, and the way he had fought for them. In a way, its a new perspective of their own way of life - sacrificing limbs in their war with Dragons. But now, with Hiccup, he fought side-by-side with a Dragon and was saved by a Dragon
In the second one, its 5 years of hard work for Hiccup, tolerating Vikings eccentricities, difficulties with Dragon problems, keeping up with Dad’s expectations for him to be the ‘Pride of Berk’ and all. And by then, no matter what scraps, whether or not you accept the Riders/Defenders of Berk as canon, you can tell Berk does see him as their hero. He always saves the day…always.
