No, I'm not that evil, Faye thought, and put the "Muscle" vial away the others. She slowly rose and unlocked the door for Mary. "I'm sorry, Mary. I wasn't really going to hurt you or anything. Its just that I've always been really sensitive about my height, and you just brought back a lot of bad memories. Please don't be mad at me" said Faye sadly.
Mary opened the door and smiled. "Faye, don't worry about it. We're sisters, and I will always love you. And I promise I will help you get what you deserve, " said Mary. By all outward appearances she was calm and unfazed, but inside Mary's panic was running loose like a wild animal. She had no idea how much longer she had until Faye started to grow. "Let me show you how it works. Please give me the growth vial". Faye solemnly gave Mary the "Growth" vial. Mary capped the vial and turned her back to Faye while she placed it in the box. "The vials need to recharge after each use" said Mary. With her back to Faye she scanned through the vials in the box. Where was it !?! Mary thought frantically. She had to find the "Shrink" vial, and quickly. She did not know how much longer she could keep up her bluff.
"What are you doing now?" asked Faye. "Oh, the vials need to be in the right order or they won't recharge" she lied. As she looked at her sister, she did a quick double take. Was Faye taller? No, she thought, just my nerves. She hoped Faye didn't catch the look of concern in her eyes. Just as she was about to give up, Mary found the "Shrink" vial and carefully applied the "Growth" label she had created downstairs over the existing label, just as she had with the "Growth" vial earlier. She knew that she couldn't remove any of the magic labels, but she didn't see any reason why she couldn't place a new label over the old one. She closed the lid and vials magically refilled.
"All done. Here, sis," Mary said handing the "Shrink" vial with the fake "Growth" label to her sister. "Drink about as much as you did before. That should get you the results you want."
"Oh no, sis, you first. Its only fair, " said Faye smiling. Did she suspect something? thought Mary. She didn't see any sign of growth.
"I absolutely insist" said Faye, as she handed the vial back to Mary. Mary thought quickly. If we both drink the mislabeled "Shrink" potion, then I should still be okay. I can just drink the mislabeled "Growth" potion later. But she had to get Faye to drink the "Shrink" potion as soon as possible, by any means necessary.
"Sure no problem, bottoms up, " said Mary as she sipped the "Shrink" potion mislabeled as a "Growth" potion. "Okay your turn".
Faye stood up and reached for the potion. Suddenly, she faltered, fell slightly backwards away from Mary, and leaned against the wall. She seemed a little disoriented. "Wait, I feel funny, " said Faye. "I think something may be happening to me."
Damn, thought Mary, the timing could not be worse. She was about to shrink even more, and Faye was about to grow God knows how big.
"Its all in your head, Faye. Quickly, drink the growth potion before it needs to recharge," said Mary desperately.
"No way," said Faye. "If I'm already growing, I don't want to take anymore. I don't want to become some kind of giant freak!"
Mary could see that Faye was slowly beginning to grow, with her head inching up along the wall. Already the hems of her pants were well above her ankles, and her shirt sleeves were becoming ridiculously short.
She was too late, and her gamble had failed spectacularly.
