Zablex wished he could just dive into Massacre's heart and seek out his Essence to learn more about them but he reminded himself he couldn't do that. He takes a breath,
"I am sorry that you feel this way but things are not always as they seem and thus doubt can grow in our hearts and we can become defensive when our world views aren't lining up with what we encounter." He looks at Massacre with a piercing gaze that seemed to see through the mask.
"Why do you Epitomes hide your faces?" He asks with simple and innocent curiosity. There was no danger and thus no need for the faceplates to be active. The only other reason would be that they had a different atmospheric environment they were built for aside from this one but, as far as he knew, they were humans and thus could survive in this atmospheric environment without issue.
