Oh! It was a great that he didn't add the knotgrass just yet. Awesome!

Gloves! Yeah! He cleaned those too, you know. Treyen didn't mind how messy it could get, everything will be cleaned after he was done with the shrivelfigs.

Squish, squish, squish...into the cauldron it went. He, then, proceeded to watch was the Professor was doing with the knotgrass and the poor gloves. Yes, he could see what she'd meant with messy, and after he was done he'll write that down with his notes.

Taking the knotgrass in his gloves-covered hands, Treyen did as told, and then added the mixture of knotgrass and whatever was left of the shrivelfigs into the mix in the cauldron.

His gloves were no longer in his hands, and were being cleaned as he waited for further instructions.
