I don't know what it is they'll see when I bring up their fears. I do sometimes know what their desire would be, since usually they're telling me what it is they want to see before I show it to them. I mainly can only sense if a person has emotions at all or not because that emotional center is what the power draws on. So... I could tell the difference between a robot and a real person I guess.
I have to be nearby, but not necessarily in the same room, no. The power has a range... it's actually wide enough when uncontrolled to screw over an entire neighborhood. I'm glad I have everything handled now.
That power sounds potentially abusable. Do we need to worry, Sir?
