I actually really enjoy seeing interactions between Hiccup and Snotlout in RTTE. The dynamic is interesting. I like this scene because in his own way, snotlout acknowledged that she belonged to hiccup (and vice versa)
Hiccup explaining to Valka how Toothless lost his tail (and partly how he lost his leg). He was so awkward and embarrassed. :) >>> he's so terrified because it's his mother: "hell hath no fury than a woman scorned"
