"What is your name?"
The poor African man couldn't even talk anymore yet Rey kept asking as if he's expecting an answer. He literally pulled out his victim's teeth one by one and even burned part of his tongue at least five times. In just an hour, the African man became a mess of blood and gore.
If it continues like this then he will not resemble a human being anymore. Lucy already captured the two other guys and did as Arthur told her. They weren't going to be tortured in the normal way, he wanted to force them to go through a special 'experience', a traumatizing one.
Lucy joined them in the room and even came up with a few torture methods that were tried on the poor victim, who couldn't voice out his opinion and only suffer through this hell.
"We'll be leaving for a bit, you can continue."
Arthur got up and left the room after he gave one final look to the African man, who had his head dropped, unable to lift it, much less talk or groan from the never-ending agony.
