MikeCable, if that is so, then the symptom is a painful paralysis from the beam instead of a stunned one from being drained in conjunction with the crystal's effect. I have taken the event as a physically hurtful change in the beginning coupled with hypnosis from the bright light in faces. It's possible that we're both correct depending on who is being tortured with the crystal. Gelflings don't seem to react as quickly and easily to the procedure as Podlings do. They, as the only kind of creature who has the power to stop the Skeksis, can be expected to have greater resistance to the monstrous experiments.
