The last few weeks of NEWTs studying had drained him, so he was a bit slower in brewing his final potion for Herbology.
While everyone else was mostly finishing, he was carefully going through the steps, rereading directions and double checking his work.
He had just finished counting down the 40 seconds before adding the water and air elemental plants - the Hibiscus and Marigold - and was waiting anxiously for the color to turn green as he stirred counterclockwise.
When he saw the emerald green color appear, he sighed in relief and added the Evening Primrose slivers with deft hands that were gloved and protected against poisons.
He withdrew the stirrer and set it aside as he waited for the potion to change colors one last time...
