Reverting butterflies to caterpillers, REALLY, everything about transfiguration at this school seemed so sissy to him. But he decided he would give it a go anyway and and thought of butterflies as he thought the spell papillio and butterflies apeared. He then pointed his wand at the buttterflies and said, "reverto", and sure enough with concentration the butter fly was now a catterpiller which he caught in his had before it reached the ground. He dicded he might as well make it a butterfly again and pointed his wand at the catterpiller saying the same spell with concentration of intent and the caterpiller was a butterfly again. WOW, he thought sarcastically as he laid his head on his desk, this class is so boring.
