Rav's body had begun to go through the real stage of corruption, as the severest symptoms were when one lost control and gave in to the savage hunger for flesh. Once it reached that point, one could turn completely at any given moment.
He hadn't meant to do that to the maid, and the realization that he had eaten human flesh for the first time, and that Angel was still out here, terrified him. He was scared that he might lose control and bite him. Only one bite, and a person would turn rogue, which was why many families got rid of any root of corruption in Nightbrook.
"Uncle Rav…" Angel called as he stepped down from the kitchen steps and began to make his way toward Rav, who immediately held out his hand and exclaimed, "Don't come close! Stay right there!"
