When Jon awoke he wasn't in his bedroom anymore. Instead, he found himself floating naked in a pool of warm red jelly. The room that held the jelly was bright white but empty beside the tank that he floated in. He couldn't even see a door.
Before panic set in, a seam formed in a wall and a portal slid open. In stepped a small, round, and purple... thing. It had six legs, one large eye, and three arms. It moved the way you would expect a living mop might move, flopping up and down onto its legs, jumping rather than walking. It flopped up to the tank and looked Jon in the eye.
"Decontamination complete," it said, although from where Jon could not tell. It didn't seem to have a mouth.
The tank quickly drained, then the walls of the tank disappeared into the floor. Soon nothing stood between the damp and naked Jon and the small purple thing. Again, Jon expected panic, but none came.
"You are experiencing our calmness field," the thing said again, "It was designed to keep you comfortable."
"Oh," Jon replied, befuddled.
"Fear not, Earth-man," it said, "we come in peace. I am Flarg-Nop, from the planet Rezflig. We will not harm you."
"What do you want from me?" Jon said, feeling at ease with his situation.
"Only to observe. Earth-beings are interesting to us. We wish to conduct an experiment. We will send you back to your home, but we will send you changed. Then, we will watch. That is all."
"But you won't harm me?"
"Of course not. We are not Zimtroigs, we are Rezfligs. We do no harm."
Jon thought about it for a moment. There was really nothing he could do to stop the aliens, but if he had to, he guessed he could always use the stone.
"Alright, let's do it," he said with a smile.
"Excellent," Flarg-Nop said. It reached up and touched Jon's head with the longest of its arms, there was a flash of light, and Jon fell into a deep sleep.
