Meet the stone

As soon as the light cleared, I darted a glance toward Julie. What I saw shocked and confused me. It was Julie, alright, but with some major changes. Her eyes were completely white, and her hair seemed to dance about as if being blown from behind. She was in a victorian-era clothing, with a white top and ankle length black skirt. The stone appeared to be embedded halfway into the chest of her shirt. She slowly arose from her kneeling position.
"What the fuck..." Chad let out.
"Julie, are you all right?" I asked, hoping for the best and still unsure of exactly what was going on. Julie started to speak in an eerie, monotone voice:
"Throughout the ages, I have been used out of malice, out of spite, hate, anger and greed. These elements have forged my will, my mind. I am the harbinger of all these qualities of mankind, and I shall bring them back upon you."
"Baby, what are you talking about?" Chad got up and started walking over to Julie.
"I am not baby, I am not Julie, I am the stone. Julie's mind will help me learn the best way to punish your evil race." She glanced her head over in Chad's direction, the stoic expression on her face giving no clues to her intent. She held her hand up and Chad was flown back into his chair. Appearantly, Stone Julie (my split-second nickname), didn't even need to make a wish, the power of the rock was at her will. I decided not to follow in Chad's footsteps and remained where I was.
"My knowledge of this world is limited to the body I currently inhabit. You two will prove useful in expanding this knowledge." She spoke, "I will go out and discover what I need to know, the rest, you shall inform me of. Until then, you two will not be leaving this room." She flicked her wrist at Chad. At first, nothing seemed to happen, but then Chad started to groan. Then I noticed that Chad seemed to be gaining weight, at a rather slow rate of speed. His neck started to puff out, and his stomach started to expand.
"uuggggggghhhh," he let out, "..w.whats happening, man! I'm getting fat!" His stubby fingers started to fumble with his belt buckle, which seemed to be straining under the increasing weight. "Do something, Jon! This is messed up!" The added fat started to make his voice sound nasal. There was nothing a could do, but watch.
"It'll be alright, man, we'll figure this out." I reassured him, and myself, somewhat. After about a minute, Chad's shirt ripped under the pressure, followed by his pants. He let out moans of disagreement as he caught sight of his belly. I had to look away out of digust. When I looked back, Chad had tumbled on the floor in a giant glob of stretch-mark covered human flesh. He was still his 5'11 height, but looked to be roughly 700 lbs. He was completely immobile in this state, but he still tried to get up. The massive rolls of flesh fought him every step of the way. "I can't believe this." He kept repeating, probably in a state of shock. It was quite possibly the most disgusting 2 minutes of my life. The looked back at Stone Julie just in time to see her flick her wrist at me.
