Thanatos had decided to go along with Lucie's little game. He was more than willing to kill the lawyer for her if it got him back to the surface. After all, he had a couple of things to do up there himself. For one, he wanted to remind his sister of what she truly was. Seeing her with a human life disgusted him, and made him want to burn down that stupid firm for doing it to her.
He also wanted to get the little girl who, by some stroke of magical luck, had managed to kill him before. Oh, he had done his research. One Cynthia Stone was going to get a very interesting surprise coming her way once he got back up there.
Now he had to playcate the devil, though. "I'm crystal clear," he said to Lucie. "Kill Lilah Morgan by any means necessary. Am I correct?" Strangely, even though now he was human, his eyes were still black. Apparently humanity didn't fix some things. The only difference now was that, while the iris and pupil were still black, the rest now had the white that humans did. He'd still stand out, just not quite as badly as before.
