"Five said... it gets better every time, yeah. It'll be great tomorrow if Ten makes a new batch." Luka says, feeling for a spoon on the table. He's hoping Gyre might have a better understanding of whats actually going on, somehow. They knew about the bubbles because they've had the soup tomorrow?

"So, what else is happening tomorrow?" He asks, testing the waters.
