When the crew forgets who they are, an extra voice is added to the mix, confusing even the most careful radio listener. The ship is running silent on a critical mission to take out a hated enemy, but when Picard gets an itchy buoy-floating finger, the XO threatens mutiny. Is MacDuff using Riker’s battle bridge as his sleeping quarters? Who is typically armed when working on the bridge? Is the bad guy grosser, or less gross than Remmick? It’s an episode that can only be heard, and never seen.
