Edgar nearly stumbled back with shock. A super mutant that spoke fairly coherent sentences? The young man quickly re-assumed his earlier position- using the rocks as his cover. Looking forward, his eyes darted a bit, he was trying to figure out what his next move would be. He pressed the back of his head against the rock his head looking over his shoulder; he called out to the super mutants before him. 

"If you aren't going to attack me maybe you should back off to show me. What's to say your friend doesn't pick me off as soon as I peak my head around this corner?" Edgar sighed before continuing. "Look, I don't know how you're talking so well, but I've seen the mess your people leave behind." Edgar knew there was no point in trying to be rational with a super mutant. Their anger and blood lust drove them. Edgar admittedly felt bad for the humans that they once were, but he knew that survival meant having no hesitation with super mutants. 

His eyes wondered as he sought an escape route should they start shooting. There honestly weren't many options. Behind him was a small rocky hill. Surely he'd be shot down before he could hope to climb that. When things got hairy, he'd have to take out the one with the rifle first. A small part of him hoped that these mutants really weren't prepared to tear him limb from limb- or more likely drag him away to perform whatever procedure that do to create more of their kind. 

He grimaced at the thought and waited.
