Char Goes To Witch School - Episode Two

"No, it's the potion to make dog biscuits!" Sophie insisted.
"I'll turn you into an eaten dog biscuit," Char muttered under her breath as Sophie turned back to the potion ingredients.
Rather than argue anymore, Char let Sophie get on with it. Sophie seemed happy to take over. It seemed like she didn't want Char to do anything, except to hand her the ingredients when necessary.
When the time was up, Miss Broomstick-Mubruoypu went to each pair in turn and asked them to test their potion and to talk through how they worked as a team. Mary and Michelle had made a potion to make fake dog poo to prank your parents with. Jenny and Emma had made a potion that made chocolate that would eat you - this potion isn't permanent. The chocolate would eat you, and then you re-appear twelve hours later with no memory. It's a good potion for trying out on a smug little whatsit.
When Miss Broomstick-Mubruoypu reached Char and Sophie, Sophie jumped straight in with "Char thought this was a potion to make dog biscuits, but I knew it couldn't be that, there was no jar full of dog's breath on a hot day."
"WHAT!" Char exclaimed. "Miss Broomstick-Mubruoypu, it was the other way round."
"Quiet!" Miss Broomstick-Mubruoypu ordered. "And what did YOU think it was, Sophie?"
"Well, I'm not sure," Sophie lied. "But I had an idea that it was a potion to give to a dog that would make them fart only when it was near you so you constantly get the blame for it."
