Josh = 12 late bloomer
Ric = spellcaster, 13, normal kid
"Ric! You idiot!" Josh bellowed, staring in shock at Mr. Mendes and shaking in terror as reality began to ensue.
"Me?!" Josh screamed back, quickly grabbing the book. "Me?! You were the one that..."
"Sssshhhh!" Josh said sharply, seeing Mendes the Jackass backing into a corner and lowering his ears.
The two boys turned and stared at their friend and mentor now reduced to a donkey.
"Is... is he still in there?" Ric said in fresh terror. "I mean... we didn't..."
"See if you can turn him back!" Josh gulped. "Quick!"
Ric frantically flipped through pages in the book and thought he found a counter spell, but was too frazzled to read the heading above it. If he had of...
"Here!" Ric said, staring at Mr. Mendes, who had risen and was know wandering aimlessly in front of them on all four hooves. Ric said the magic words and concentrated on Mendes, who stiffened sharply on his legs as if hit with something.
But he didn't change back at all. Instead, Mr. Mendes the donkey very quickly seemed to pull into himself and suddenly shrank away in a sudden puff of grey smoke.
"RIC!" Josh cried, eyes. "You fucking idiot! Y-You killed him! Oh my God, you killed Mr. Mendes!"
"N-No wait!" Ric choked back tears. He very carefully approached the spot where Mendes had been and frantically looked around the floor. "No... nooo..."
"Give it up, dude! You fucking killed him!" Josh began to whimper. "You killed our friend!"
"Oh, thank God!" Ric cried, suddenly exhaling sharply as tears fell. He plucked a tiny spec off the carpet in between his fingers and gently placed it in his other palm.
Josh leaned in and the two boys stared at a tiny trembling donkey, no bigger, if not smaller in size than an ant.
"Holy shit, dude." Josh said.
