"No, I don't think I do," Thanatos says as he tries to hide a yawn behind his hand. It's not a lie really. Zagreus is the only one he's pulled form the brink, and he's hasn't tried it on anyone else. Internal moral debates aside, he wouldn't announce that he had the ability to use on others. He'd hate for anyone to get lax with their own self-preservation. (Chasing after Zagreus is enough!)

"But I'm glad to know another healer on the train in case things go wrong."
