"What are you doing? !", shouted the principal's wife in surprise.

"Nothing , I'm just giving Billy what he deserves!"shouted Medusa.

"My husband is out there! He'll get killed!"

"That's his problem, not mine. He could've let Billy go out alone. ", she replied coldly.

" Why?", asked the science teacher. "Why should he be out there alone? "

By now everyone was confused. They could hear the terrified screams of poor Billy outside. They didn't hear the principal though.

'Is he dead?' The question hung in the air, but no one dared to ask it.

"Why ?", asked the science teacher again.

Medusa couldn't handle it any more.

" Because I don't like him! ", she screamed out eventually.
Then came the moment of truth, "Billy is so good in science and I'm not, although I used to be until he came along. I got so angry, I decided to mess up his experiment, so that his fame could be ruined. I wanted him to think that he's bad in experiments and science, give up and then I'll be the best in the science class. "

Tears were streaming down her face now. The more she heard Billy scream, the worse she felt.

"So this entire thing is your fault, just because you were jealous? !", shouted the principal's wife in anger. "You put people's lives in danger just because of jealousy? !"

Medusa nodded in sorrow, her face stained with tears and eyes blood red.
Outside Billy was still screaming.
Sarah walked up to Medusa and gave her a hug. After Medusa's crying slowed down to merely a sob, she asked,

"Can you fix and reverse this experiment Medusa? "

Medusa looked up and replied, " Yes. I can, but what I need is in the science laboratory. "

Sarah smiled and said, " Then let's go and get it."
