"I'm just watching her go."

"I understand that, but you can't watch from there." He was foreign, his accent heavy. I didn't move. "Sir!"

He had no idea who, or what, he was dealing with. At my age, I was exceptionally adept at controlling the beast within, but with just one look... Even in this crowded airport, no one would know what happened.

"Sir!," he barked loudly.

I turned. Our eyes met, and he crumpled to the ground.
