"You've almost got it," Ruelle said, leaning over to point at the equation. "You just missed a step here—see?"
"Ah… right." Leslie's brows drew together, who sat beside Ruelle. Her hair fell forward as she bent over her book with the quill in her hand. "I forgot."
Right now, three lanterns burnt brightly in the room, their glow spreading across the table. The books laid open along with notes spread out between Ruelle, Hailey, Kevin, and Leslie. The faint rustle of paper and scratch of quills filled the room.
"That's alright," Ruelle assured. "This one is trickier. It's not the formula—it's the amount of ingredient to use that catches people. Once you remember which ingredients use which percentage value, it's straightforward." She slid her notebook toward Leslie. "Here. Copy these down—they'll help."
Leslie's mouth twitched, the ghost of something that might have been gratitude—or hesitation. "Thanks for helping me again."
