"... I'm getting Ryo." This doesn't need Ryo's power. Thanatos doesn't have to worry about Ryo potentially over exerting himself with this, and Ryo will know how to handle someone who can drown himself with a small glass of liquid. "If you're too addled to drink water, you need more professional help."

Mort agrees. And if Ryo can't help, then Lagos can yell at Wash some. Lagos is good at that.
