One day, Captain
Khan pulled out his medical tricorder and did a quick scan of the ensign, who had stopped his rage against the atmosphere but was still giving the appearance of speaking soundlessly. "Other than obvious signs of stress," Khan said, "there does not appear to be anything wrong with MacAllister. Not even laryngitis." He put the tricorder back, and added, "If I didn't know better, I'd swear he was carrying out an old Terran practice called 'mime' that was eradicated in the late twenty-first century. See, he's making no sound and pretending to be behind an invisible wall." MacAllister reached out to the doctor with a pleading look on his face, and Khan attempted to take his hand … but was blocked.
"He does not appear to be pretending, doctor, unless this 'mime' is contageous," Storvik said, as Khan also placed his hands on the invisible wall surrounding MacAllister. The Vulcan pulled out his technical tricorder, and scanned the area around the ensign. "It is a force field, created and maintained by the holoemitters in the corridor. Fortunately for Mister MacAllister, the computer's safety protocols are rendering it permeable to air so that he does not asphyxiate. It is doubtless also the holographic system which is dampening his speech so that we cannot hear him."
"Medical override," Khan said aloud, directed at the computer. "Release Ensign MacAllister from the force field, and deactivate the sound dampening as well."
"Aw, man, thanks," said the ensign. "I was beginning to think—" The ensign stopped, a look of shock on his face as he nearly fell over. He pulled himself upright, but with an apparent great effect. To all appearances, he was struggling against an invisible wind.

Before the Vulcan could deactivate this latest manifestation of the holographic system which was active throughout the majority of the USS Murgatroid's interior, ensign MacAllister was blown down the corridor by a mighty wind which no one else felt, and slammed into a bulkhead. He slipped to the floor, unconscious. "Who would," the Vulcan started again, and then was joined by Doctor Khan as they both said simultaneously:
