Ava looked over at her father when he said her name sharply, about to argue with him over this matter. If she went, she would find a way to escape and come back. But not before freeing the dragons there and taking out any chance of Einar possible winning a battle against Berk She wished she could convay this to her father, but she could't without tipping Einar off to what she was thinking as well. Besides, even if she had tried to speak it, Blizzard had lept at the man, the two tumbling, leaving Ava wide eyed and unsure how to help her friend at the moment. She screamed out his name when she saw Einar strike at him with a knife, "Blizzard!" She panicked slightly and watched as Toothless managed to tackle the man off of him. 

As the man went to his boat, Ava rushed to where Blizzard was, looking at the wound, a worried look on her face as she looked up and heard Einar's threat. If she didn't go with him before that time, Berk would be attacked by the Skrill. She knelled down next to her dragon friend as the fiend rode off in his boat, looking a the wound, relieved it wasn't to deep, meaning it was at least non-fatal. She looked over as Aurora approached as well, licking her son's wound to keep the blood from escaping any more and looked to her husband to carry the younger dragon back to Hiccup's home. 

As the two older dragons took care of Blizzard, Ava looked back to her father, worry filling her gaze, "Dad, the Skrills. If I don't go with him he'll have the skrills attack the village and a lot of people could get hurt! Even killed! I have to go with him."
