Astrid's known you since you two were kids, you were best friends. She knew you well enough to know when something changed, and she had noticed a change. Ever since the idea of someone new coming to hurt dragons, she noticed the change. She hasn't said anything out loud, she but she was taking note of how and when the changes happen.

The entire gang had just sailed across the bay to a nearby island, giving the dragons a break after a long fly. Snotlout claimed to have heard a dragon, and low and behold there was a baby dragon injured and trapped in...well a trap. Hiccup had gotten the dragon out, but still had to make some sort of cast for it. Astrid stood off to the side, watching everyone quietly. She noticed you as well, standing further away and staring silently at the baby dragon.

You couldn't control your thoughts, they were good and bad. It was hard, but you didn't want to worry anyone so you kept them to yourself. The whole idea of having a new person going after dragons was stress inducing. The thoughts started there, and they've only gotten worse. Looking at this helpless baby dragon made some thoughts start, but you didn't want to think about it at all, it was evil after all, you weren't evil...right?
