Aurora could some what see the strategy Hiccup and the night fury were using. Pick of the three Vikings and the dragons up above wouldn't have anyone to give them orders. It was rather simple really, but would indeed word very well. She watched as Toothless swooped down below to the group and threw one of the men into the water before dashing back up again. She watched all of this closely. Toothless hid int he clouds, leaving the three dragons above unsure where to find him, as well as the other two Vikings left on deck to yell at their dragons, trying to get them to go into t he clouds, but the dragons were too nervous to do so and hovered there, looking about for any signs of him. 

The two Vikings had turned their attentions to their dragons and trying to see Toothless in the clouds. Raising her head slightly, her rainbow eyes narrowed and she saw a bit of a good opportunity. Their backs were turned to her and while her legs and front paws were chained down unable to move, her tail was still able to move. Puling it back carefully so as not to alert them, she then swung it forward with a powerful swing, hitting onto of them as hard as she could so the Viking went flying into the water. That got her hit painfully again, but at least it was just down to one Viking. 

She looked up, her eyes searching, hoping Toothless and Hiccup would hurry. They couldn't let this small ship get far. It was unknown if this smaller ship had a large one waiting on it and she would like to not find out if she could help it. There was no other ship in sight, so she took that as a good sign, but the threat was still there and she wanted to get back to Berk as fast as she could just in case.
