Soap, Ghost and Gaz just cleared out a lab.

when they entered a room with several danger signs, they saw a Wide but short cage.. with black feather's around the room and blood

That's when they saw the sign next to the cage. "Demon". And looked at you (the experiment) with blood all over you in horror and disbelief

Soap: W-what f#ck is that...

Gaz: A-a Demon! ? how is that even possible!?

Ghost: Be careful Soap, Gaz this creature might kill us point a gun at you
