John closed his hand around the Gryphon vial. That was his answer, but he needed to make sure the new Amy would listen to him, after all she was a person now and she'd acted like she didnt know him. Searching through the vials he found one that said mental augmentation, and one that said obedience. He hoped that these would work to restore her and make her listen to him.
"Hey sis," The tween said. "I think someone's at the door."
Amy looked to him. "Oh ok! Ill go check." As she left, John spiked her food with the three vials and then waited for her to return. She came back in frowning. "Hmm, no one there."
"Huh," John said. "Well we gotta do some chores outside once your done eating remember?"
She looked at him quizically, but nodded. John was glad he remembered this since a gryphon wouldn't fit in the house. SHe bit into the food hungrily, and once she was done, she and John went outside.
John held his breath as he started to notice her hair becoming softer, more like feathers. She continued working unawares even as her clothes started to rip and leonine features began to overtake her lower body even as bird ones overtook her torso and face. In moments, a beautiful sandy colored gryphon stood there where she had been.
"Becky?" John whispered, approaching her. The large beast bowed its head to the little boy, nuzzling against him.
"Master," She said. "You know my name is Bechana..."
John gulped. Now his horse turned sister was his Gryphon. Looking around he found a saddle. "We need to find Amy." He said.
