How he didn't want to know. He just wanted to finish eating, finish his chores and go to bed. But dammit. Heracles-who-was-no-longer-Heracles couldn't just dangle what he said in front of Zeus' face and not explain. Who would be interested in their meeting? Did Heracles know that Will was actually Zeus?
Zeus looked at his son carefully but saw no hint that he knew or even suspected anything other than the image Zeus chose to show. "I'm not like other residents. I let the drugs eat me up but I've been alive longer than I've been addicted. I know what it's like without them and unlike them I'm not afraid of it." The real question became if, when he got out of here, if he had a reason to stay clean. If he had someone to come home to, someone to care for and care for him back he wouldn't need the drugs since that was the reason why he'd abused them anyway.
"Who was this 'someone' you met who was interested in our meeting?" he finally asked. "I know a lot of people who would rub anyone the wrong way even you."
