Yes - but it behooves us to speak publicly also.
He continues aloud.
"One of the persons you met today was what we call a BLIP: a human born with latent immunity to psionics. For some reason, he lacks any susceptibility to psychic powers - nor could he learn a discipline if he wanted. You could not even find one with psionics, although if you tried, the void where you might find his soul would certainly alert you that something was amiss.
Some say this is a genetic anomaly. This is possible, but I feel it is more innate than that. I feel such people lack an empathic connection to the rest of the human race. This is important, because it means they are also clinically detectable as sociopaths.
I am impressed with you because you divined the way to affect a BLIP nonetheless. He cannot prevent powers from affecting the environment around him. Fire, from whatever source, will still harm one. If you remove the floor from underneath one, he will still fall."
Oblomov smiles.
"And yes, feats like that are possible."
