The demon within the boy could see that the Black Angel's time was running out. She was being drained of blood and quickly. If he would not act to gain his attention soon then his honour would be scratched. Yes, a demon with honour. I know what you are thinking but to be freed from imprisonment. That has some kind of payback, at least to the demon it does. Not all demons are set on complete back stabbing and destruction, because this one wasn't. As the patience of the entity grew dim he let out a tremendously loud and deep voice from the small boys throat. Inhumanly loud and inhumanly deep. Not as loud to have been heard in other rooms to the point where it was crystal clear, but loud enough and bizarrely deep enough to catch the attention and probably lunge shock and awe into the receiver.

"Release! Her! At! Once!" The boy ear-piercingly spat.

The boy stood still staring at the experiment but his face was scrunched up in a inhumane way of anger.
