In 2367, Guinan played Gloria along with Jean-Luc Picard in the role of Dixon Hill. She entered the office of Hill eating chewing gum and meeting Madeline, Hill's secretary. Madeline told Gloria that Hill wasn't available, but Gloria told her that she was his cousin from Cleveland.
Following a conversation Gloria rushed into Hill's office where she and Hill were threatened by Johnny who wanted his money back from Hill. When Johnny was shot through the window by machine gun fire, Hill pushed Gloria to the ground. (TNG: "Clues")
