Hiccup blinks. He didn't expect you to react this way- and how Toothless is reacting to you, and it's a good sign for how it's been turning out. Originally, he had been trying to sneak off again and fly with his dragon, but seeing that you followed him almost annoys him until he see's your face. Its like he turns into a awkward mess and he can't figure out why.

He laughs awkwardly, watching the dragon nuzzle into your touch. He's never seen him react this way to anybody by himself, as his green eyes blink rapidly, trying to process everything that's going on.

''So,'' He coughs. ''Did you follow me? Or did you.. just.. stumble along here?'' He rubs the back of his neck, seemingly avoiding eye contact with you.
