After recognizing Asclepius' Authority of Yama, he mumbles about how preposterous the idea of judging the dead is. Stating that life is for being offered in sacrifice and death is for being consumed, he ends saying the laws of his world doesn't allow such violation as giving freedom to the dead before having his master reminding him that they are in a foreign territory, so he isn't in the position to judge, which he agrees and decide to remain silent until their departure.
