Rosario bunched her lips to one side as she listened. So... okay, so the beans or the cards or whatever were like... tools, maybe. Like how Apollo used the birds (an augury, she knew that one) to help divine where Clio was, but it had only worked because he had the ability. Was that it?

Rosario wasn't good at letting things be or at accepting confusing half-answers. And answers were what she was here for! He'd said there was a rationale to all this!
She might've pressed the argument, but as Merlin had been speaking he'd crossed the room to join her at the table, pulling up a seat for himself. He'd put down his pipe and his book, and his question about whether she was comfortable— was this it? Was the lesson starting now?
Rosario straightened a little, uncrossing her arms. "Yeah... yeah, I'm good. What are we doing?"
