Valid points. I was more thinking about elevator in a hospital / ICU / emergency room. Somewhere that a person rushing through and brushing against / bumping into someone would not be noticed by anyone, including the one healed. Same talent, different application. Trust me - drama or theatrics is the least thing I would want if I could do that.

This also addresses that "I decide who lives or dies" situation. It is quick, not necessarily making a choice for or against anyone based on any predispositions.
