Lightning
When Madame Morrible first learned how to control the weather, she was petrified of lightning. Lightning could kill, and when she was in school she had no thoughts of ever killing.
Her teacher had told her to use her fear to her advantage, to make the lightning fear her.
But she wasn't sure how…until one day, she saw a bolt strike a dead tree and light it on fire. She thought about putting it out…but decided not to.
The bolt and the fire that followed had lit a spark in her eyes, and Morrible waved her hand…and another bolt came crashing down, this time in a lake. She did it again and again, laughing with joy.
And from that day, Madame Morrible no longer feared lightning.
