Firefly Glen in shape no bigger than an agate stone

She was throwing all of these names at him, and he could feel the rage growing. His breathing started to get faster. He obviously knew he had to have a mother somewhere, but he had no memories of her or her name--and a brother? He didn't remember a brother either, or this woman in front of him, or any of the fucking names she kept saying. 

His breaths started coming and going even faster, his ribs rising and falling with each action. Just stop with all the names, he finally said through clenched teeth. I don't....remember....any of them, the confused beast spat out between breaths. He hated this fucking feeling--like there was something he should know but his messed up brain wouldn't let him remember. 

He started to pace, his breathing getting even faster as the rage grew. He didn't want to lose it in front of this stranger, but it was all beyond his control now.
