Grimm shot up hearing his door being thrown to the ground with a loud clang. He was in a state of shock for a bit. He shook his head out, and walked towards him. Revealing his alien form.
"Hello human," Grimm said in his native tongue.
He was trying to be awe inspiring. After all why shouldn't this human be surprised to see an alien? It seemed to be the usual reaction of his prey. Before he killed them. Though this strange white haired man wasn't his prey. He was to be an ally. At least for now anyways. As he walked towards the door he recoiled from the exposed Delphite by the door. He hissed out in pain as he took steps back. 
"Damn Delphite," he spat in perfect English.
