This room wasn't where he'd gone to sleep. It was a rather frightening notion, being dragged off in the middle of the night by unknown groups of people. Waking up here, he made a number of observations. The room was clean and well-kept, completely white and clinical. There was no visible exit of any kind. Lastly, there were a group of other people in the room with him. Having made these observations, he realized that he was terrified. The most terrifying thing wasn't that he had woken up in some strange location, nor the strange people he was locked up with. It was the fact that he couldn't recall where he HAD gone to sleep, nor anything else about his life. He knew he had parents - logic dictated it - but he could not remember which parents.
So, to calm himself, he went through the things he had seen and the logical conclusions he could reach.
This facility was high-maintenance. White took a lot to keep clean, the lighting was excessive, and the voice of the strange woman who called herself Echo came from hidden speakers, undoubtedly. So he was being kept within the institute of an organization, and most likely not a criminal one. Either the government, or some large corporation, was in charge of this facility. Small-time criminals or even gangs couldn't afford to keep this place going, especially if it's size extended far beyond this room. The drugs necessary to create the amnesic effect he was experiencing were also quite hard to come by.
The people who had been collected fell within a specific age range. This meant that whatever reason they had been brought here required them to be similar to some degree. Both males and females were present, and there was even a girl without arms. The options then included a ransom, clinical trials, a social experiment (with memory erasers?) or alien abduction. The last was rather absurd, but potentially was the best explanation for the application of amnestics. And it was important to keep an open mind.
The idea of a ransom fell by the wayside based on his earlier conclusion on who the perpetrator was. Even if the government was performing ransom operations, or if a large corperation was sponsoring such activities, they wouldn't do it in a fashion that would so directly lead to themselves. Minimize the risks.
The fact that no kind of drugs or medication had been presented made a clinical trial of some sort unlikely, and as such a social experiment on memory loss was the most logical option. He had either naturally lost his memory, or he had been given a temporary drug that would have the same effect. The observations of Echo, the presence of others, and the large button that required the input of others in order to function definitely pointed in the direction of social experiment as well.
That was a rather calming thought.
Of course, this entire deduction hinged on the fact that his amnesia was shared by the others. This was something he would take on faith however, as he was not sure what interacting would bring him. The most intelligent thing to do was to see what happened when someone pressed the button from a distance, to not be the first sheep over the dam.
