(Ye didn't wait long enough; people get on at many different times, and I would've posted regardless.
Also, were they surrounding him eariler? A terrified mouse would freeze at first, but the instant it thought it would be attacked it would bolt out of there along the shortest, safest route. You just don't get a chance to do anything when you try to catch a mouse by hand.)
How can you know which are real and which are false? Well, the stuff about history doesn't really matter, only this company's current power and state does. We know we have cool powers, and we know these guys deal with cool powers, so it makes sense there are greater and cooler powers about, but it's also possible that there haven't been any powers past "E" on that scale yet. We know that they have this one facility, and it contains a horror maze with some number of subjects that, in all probability, are allowed to escape sometimes for "real world tests" or something similar. These sorts of people very likely had cameras in the elevator you used, and guards on hand to run after and tackle you before you got 15 meters away. So as far as guards and basic manegement are concerned, you proved yourself not to be very useful by settling down, thus failing your test and deserving death (with one last chance at redemption). However, if there are entities from beyond outside the bounds of normal physics (guiding the company and world), they probably know what you've done and consider it a little (happenstance|step in the plan). They (we?) may or may not tell any of their puppets, including you, but that doesn't really matter yet; just try to do your best.
We know that our powers take energy and control; they can be pretty hard on us. So, remeniscent of the whole "with great power comes great responsibility", the higher powers will probably take more energy and control, and the god-powers would require ridiculous amounts of energy and inherently superhuman amounts of control. So if there are "subject-Zs", they must have at least one way of using energy outside their relatively tiny bodies, and have control systems secondary to their brain to handle it all.
So obviously, your next step is to find someone who doesn't use their brain much, then see if you can get it to produce energy for you during the lull times, or act as an extention to your mind with the off parts.
