Eric could understand the violence, the need to display the carnage and the atmosphere that demanded it. He was born into violence, even before he had met Macklyn and had transformed into what he was presently. He understood the need to kill, to make someone suffer for their wrongdoings, to fight and to win. That was his core, the heart of what had drawn him from the grave in the first place, that vengeance.
Lee had been struggling for a while to get him to not kill. Even Dinah had tried to sway him, and though he had promised to stay true to his course Eric knew that he was a killer. Now more so than before, the vampire part of him demanded the violence while the fairy part was more passive. He didn't struggle near as much as Macklyn did with it, but he felt the constant warring of the sides constantly in spite of it.
Watching from the shadow as the scene unfolded before him, Eric sighed. Back pressed against the warm brick, he waited until John was done and the girl had scampered away in a mess of blood, fear and whimpering, before he made his presence known.
"You've had an exciting night so far," Eric said softly, watching his friend. "Are you alright?" John seemed more aggressive than usual. Or maybe Eric just hadn't seen the true vampiric side of his friend. He hoped John trusted him enough to confide in him if he needed it, but he understood how that might be too much to ask of his friend. Either way, he would be there for John if the man needed it.
