Tay's line of business sounds like Dean's. If either could die at any moment, only Dean won't... so Zack says nothing. Or he might inadvertently start blabbing about the mark, and that's not for him to bring into any conversation.

Tact. He totally has it.

Except when he doesn't.

Instead, he winces at the mention of scars and coral reefs. "Human bodies hurt," he grumbles, more in solidarity with Tay than anything else. Walking into the door when half asleep is uncomfortable enough. Being cut to ribbons in salt water doesn't bear thinking about.

"Not in the mood for the usual stuff," he tells Dean. Zack really is feeling good and awake now, so he gets up and starts clearing the dirty plates.
