It really was like he had stumbled upon a buffet and he was enjoying every moment as the strong emotions washed over him. The only way it could have been better was if he had taken the time to get between them and absorb the life force of the both of them at once but he was getting far more than he needed now. And truth be told he wasn't wholly comfortable with killing for his own needs, quite the change when he was willfully and gleefully taking lives at the behest of his father.
It was all different now though. He had a body now.
He didn't do anything as showy as lick his lips or look anything other than impassive as he fed off their fear. He did close his eyes a moment, knowing his eyes were likely a bright and brilliant glowing red at the moment. He did open them again, glancing down at the grass and taking a few steps back to avoid the magic. He was versed well enough in it to know vaguely what the boy was doing, and now what this woman was attempting, but he wasn't at all concerned.
