Her Worst Nightmare

Everything was getting out of control and though Aldric loved the chaos, it was spinning out of his control. The human was moving faster than his plans and he loved to be in control. 

It did surprise him though, he presumed Islinda was a dumb human but she was more interesting than he thought. He recognized the Iron arrow she purchased, the weapon that could very much end his life if she struck him in the heart. She was making a great fortification. 

But humans would always be weak because she hesitated again. He could see the emotions; the conflict in her eyes. Aldric expected that with the weapon in her hand, she would strike at him, and perhaps, with the crowd around, they would be enough to subdue him while the Iron weakened him. 

Yet, she didn't. 

Why?
