Crewwoman in shower
This sciences division crewwoman was found dead by Geordi La Forge. He discovered her in the shower with her clothes on in one of the personnel quarters aboard the SS Tsiolkovsky in 2364. La Forge contracted the polywater intoxication from this crewwoman as he caught her falling out of the shower.
Later, while determining the cause of the intoxication, William T. Riker recalled someone taking a shower with their clothes on in the historical database, later determined to be aboard the original USS Enterprise. The mention of La Forge's note of the crewwoman taking a shower with her clothes on triggered Riker's memory enough for Data to discover the cause of, and for Dr. Crusher to discover the subsequent cure for, the intoxication.
