Aurora, when the two humans moved forward to try and pet her, stepped back, keeping low to jump out of the humans' reach, but thankfully the human Hiccup stepped up, telling them to not come near her. Good. Because if it wasn't obvious that she didn't want them near her by her tense body and slight showing of her pearly white sharp dagger like teeth, then they deserved to have their hands bitten off. When the humans backed off, she sat down and glanced around. 

This town was very similar from the village she had been in before. Only with differences. For one, these dragons seemed willing to help work around the village here, where as in the other village they were chained and forced. And here there seemed to just be a more....pleasant mood. It was like comparing the moon to the sun. One was brighter and more productive then the other. 

Standing up again, she moved over to Hiccup and humming softly as she rubbed her head under his chin and at the same time, made sure the other humans were far enough away from her. This Hiccup was her human. The others were not, so she did not trust them. And probably never would.
