Cass looked around the room, trying to see how the others were doing it before reaching for her own billywig stingers with one hand, while her other hand made sure that the potion was still slightly swirling.

Oh, what if it stops moving?

But she didn't want to think about that, because if it did, then the potion would go bad, and Lafay would get mad, and she might get potion spilled on her head too. Oh no. She didn't want that. So, she simply bowed her head down, seeking to be invisible as she dropped her billywig stingers at the slightly swirling liquid, thankful that she had done it.

Then she wiped her forehead with her arm, even though she hadn't been sweating and waited for the next next set of instructions as she pulled her gloves off for a moment to take the time to write her notes....which she still couldn't see properly.
