Their first flying scene illustrates Hiccup and Toothless' bond perfectly.Complete with Forbidden Friendship playing in the background.Nothing looks and feels more adorable than seeing it and it goes to show just how much their friendship has grown since they first met! Hiccup even gives a tiny, subtle smile ◊ when he notices Astrid is braiding his hair.Which makes it even more adorable when watching her braid his hair in the movie.DeBlois announced that in some recent editorial news, that Hiccup doesn't actually like the braids in his hair, but puts up with it for Astrid's sake.At the ending, when Chief Hiccup is participating in the dragon racing game with Alpha Dragon Toothless, he puts the winning sheep in Astrid's basket.In other words, Hiccup put those on his suit to remind him of his Astrid. The dragon that his girlfriend of five years rides on. In fact, if you look closely at the side of Hiccup's helmet and the red marking on his strap, it's a Deadly Nadder.It's the many small moments between the two that slowly reveals how much they love each other without ever making a big scene out of it. The fact is there's no one moment, outside of the explicit moments (the various kisses, particularly) that speak to their romantic inclination.You can see it in how casually they enter each other's personal space. To put it simple terms, they're obviously in love without needing to be obvious about being in love.Its hard to explain but one gets the sense they are "meant to be together" when watching them that wasn't really present before, a subtle way of showing how their relationship has matured. There is no real nervousness or hesitation anymore, and they don't even need to act outright romantic for one to see how in love they are. All the above boils down to a palpable level of ease in their interactions.When he surrenders to Eret in order to meet Drago, Astrid clearly is not sold on the idea (going so far as to ask, "How is this a plan?") but follows Hiccup's lead. Astrid clearly trusts Hiccup unconditionally now.
