Background information
Diana Giddings was played by regular extra and stand-in Lorine Mendell. She was seen in many TNG episodes, in the first season usually wearing the skant uniform style and working in Engineering. Her name was never spoken in dialog (the script of TNG: "The Outrageous Okona" calls her "A well-endowed female crewmember"; in the script of TNG: "Power Play" she is called a "supernumerary"), but it was barely legible on her door sign. The Star Trek Encyclopedia gives her name as 'Dianna Giddings' but the sign on her door reads more like 'Diana'.
