Her human-like mannerisms were curious to Ren. She seemed to know and understand them well enough to mimic their behavior pattern quite effortlessly. How long had she been around them? Must've been a while he concluded, his eyes not leaving the petite figure despite his query to the doctor. His smile widened at his reply. "Oh, are you sure doc?" His tone was of mild playful surprise, though he did take a step or two back to give the impression he was being considerate of the woman's feelings. Whether he was intentionally doing so was unclear.<br/><br/>"Kol." Ren sharply quirked his head to one side, "Koool." He said her name again as though simply trying it out on his tongue to test the sound of his own voice. An angel, and now this demon? He wasn't sure what to make of anything in the moment. "What sort of name is that?" The question may come across abrasive, as it certainly was. Though perhaps not deliberately, to his knowledge humans didn't have interesting names like this. But his attention seemed to wane on the topic and almost immediately as another thought seemed to have registered. "Did you come with the angel? I would very much like to meet him. If it please you. Kol." Each sentence seemed to break with an unexpected pause and then jolt into the next as if he were distracted. However his eyes remained sharply on her throughout the entire exchange, as if to make her that much more acutely aware of the fact he understood what she was trying so hard to hide.
