When there was a knock on the door, the still invisible dragoness stood p and watched as the Hiccup opened the door. She was not happy at all to see the human girl there, and more importantly coming inside the house so rudely. She already didn't like this girl and her acting this way was sure not helping her case in Aurora's eyes. She took a few silent steps forward and when the girl punched him hard enough to make him stumble back, she shifted then, showing herself to them and went over to Hiccup, sniffing him to make sure he was okay before her angry rainbow eyes looked at the girl, a growl forming in her throat as she stood protectively in front of Hiccup. She didn't care if the girl was doing so playfully or not. She didn't like anyone hitting Hiccup. After a moment of growling, she sat down and stopped the angry noises, though her hard gaze didn't leave this girl, obviously not wanting her to get too close to Hiccup from the way the dragoness sat so close to him. She moved her tail,so that it layed on the floor around Hiccup's feet and then curled herself around him, purring to him and rubbing her head fondly against him.
