Lisa is a secret demon, I’m betting.She somehow found out about the hero and was sent to corrupt him.She might even be the source of his eyes.I’m also betting that his eyes wouldn’t work on that priest for some reason, and she was the one who brainwashed the new priest.That or the new priest isn’t brainwashed at all.And because Lisa isn’t brainwashed, she won’t glow when the potion is spilled on her.That said, I don’t know why Soara didn’t tell Tori that it was Lisa’s idea to not only replace her, but to sell her into slavery.
