Suddenly, Robert heard the clicking of the dials on the gun and turned around, still holding Amanda with one hand. He saw Jess pointing the gun at him.

"Hold still," she smiled at him, and fired. Robert closed his eyes, expecting to grow even bigger, but after a few seconds, could feel his body traveling downwards.

Robert opened his eyes and looked down. Luckily, his muscle mass remained, but his height was decreasing pretty rapidly. He glanced over at Amanda and noticed that she, too, was shrinking along with him.

"Uh, Jess? Honey?" Robert said. "What are you doing?"

"What does it look like I'm doing?" Jess answered. "I'm taking away your height."

"How small am I gonna get?"

"You'll see," Jess replied. The process continued for about another minute, with the room growing ever larger for the two siblings.

Finally, it stopped. Robert placed Amanda next to him on the floor, and the smaller girl stood up. She still came up to his navel, but because the two of them just shrank, she had to be much smaller than her original height of 5'4" at this point.

Then, Jess walked over. She stood in front of Robert and she noticed that his head barely reached her crotch. Glancing over at Amanda, Jess saw that the tiny girl was about even with her knees.

"Wow," Jess commented. "I really have to hand it to you, Amanda. This gun is impressive. Too bad you were too stupid to figure out how to work it properly." She bent down and grabbed Amanda by the back of her shorts and hoisted her upwards, stopping when the two were at eye level.

The larger girl's face loomed in front of her shrunken foe and she smiled evilly. Suddenly, and without warning, Jess flung Amanda over her shoulder. She hit the couch, bounced off the coffee table and landed with a thud on the floor below, knocking her unconscious in the process.

"Amanda!" Robert yelled out, concerned for his sister's well-being. He started to run towards her, but before he could get even a step beyond Jess, she grabbed him by the ankle and tripped him up.

She let go and held him down with one of her feet, while turning the dials on the gun again. Suddenly, she lifted up her foot and fired down at him and he began losing muscle mass.

When she was satisfied with his size, which was much smaller than what he was even before the ray gun had affected his body the first time, she let go of the trigger.

Jess reached down to pick Robert up. When her hands were inches away from his body, he grabbed the gun and threw it as hard as he could across the room, landing near his sister.

Jess looked down at him and sighed, a little annoyed. "Now why did you do that?" She glanced back to see where the gun had landed, before turning her back on Amanda. "Do you really think that pathetic little worm of a sister you have can actually use the gun before I take, like, three giant steps over to where she is and pick it back up?"

Amanda stirred slightly, opening her eyes and seeing the gun right next to her head.

"And besides," Jess continued. "Even if she could use it, the gun is too big for her now, anyway. Just what did you intend to accomplish?"

Amanda reached out and gripped the handle of the gun and it magically shrank down to accomodate her smaller hands. She slowly and silently began turning the dials on the gun again, hoping not to raise the suspicion of Jess in the process.

"And finally," Jess concluded. "I'm the one who--"

She stopped speaking once she heard the familiar hum of the ray gun behind her and she turned around to see Amanda holding the gun, clutching her side, where she had struck the coffee table when Jess threw her earlier.

Who does Amanda fire at?
