Char Goes To Witch School -Episode Three

"Well, let's test it," Miss Broomstick-Mubruoypu said.
She magicked a dog out of nowhere, which sat with a dopey expression on it's face on the desk that Char and Sophie were working on. Miss Broomstick-Mubruoypu put a spoon in the cauldron and then fed the potion to the dog. After that, the dog was plonked on the floor and it immediately ran over to Emma and Jenny.
"Ew, Jenny!" Emma exclaimed, waving her hand in front of her face. "Have you dropped one? That smells like socks that have been worn on a pair of sweaty feet and then left in the laundry basket for a week!"
"It wasn't me!" Jenny insisted. "It was the dog."
With a wave of Miss Broomstick-Mubrouypu's fingers, the dog vanished.
"I think this proves that Sophie was right," she announced. "Now talk me through how you worked together on the potion."
"The only thing Char did was hand me the ingredients," Sophie said. "She refused to do anything else."
Char opened her mouth in surprise.
"Wait a minute!" She exclaimed.
"Enough!" Miss Broomstick-Mubruoypu exploded. "Now, zero points for Char and Sophie for zero effort on teamwork. You are now all dismissed for lunch!"
Char caught the nasty smirk that Sophie gave her as she turned away.
