... you assign the exact same complex business problem to both a narc and a well performing non-narc for them to solve individually with a set deadline? I.e. who comes up with and implements the best solution? How will the narc react to said assignment? Will he accept the challenge? I am trying to find creative solutions to point out the narc's incompetence.

Obviously if I can't control my facial expressions, I should keep my camera off when on a call with the NPD, right? But what should I do if I can keep a neutral face on camera when grey rocking? Should I keep it on or off?

Edit: the NPD isn't my boss but rather a colleague on a contract. I've recently exposed his narcissism to my boss who appears supportive and understanding.
