Vi continued her work, sewing on the fabric and creating a red tulip on her square. Then she paused and glanced up to hear Professor Marchand speaking again. A riddle? She flicked her eyes towards Ace who seemed to be pondering the answer to the riddle. She paused and then thought that it might have been Diffindo but then again... Was that answer too easy. "Is it a variation of the severing charm?" she offered. Not exactly the severing charm but something that was focused on fabric and sewing and all?

But also... Use to cut ties with mistakes or simply when you need a break...

Perhaps it was just Diffindo and she was overcomplicating.
