Absolutely. Under the circumstances you describe, I definitely would. Ask him why he is doing that with his eye all of a sudden. Then talk about the possibility of it being a twitch as a result of the pressure he’s under. If, in fact, his twitch is a physiological manifestation of stress with him, the physical problem can get worse and/or affect other parts of his body (bowels, heart, etc.) and you don’t want that to happen. HE doesn’t want that to happen.
