with a former lover, the newly assigned first officer to USS Enterprise, Commander William Riker. In season one, she meets a potential spouse in "Haven". In later episodes, Troi has romantic involvements with several others, including a brief relationship with Klingon Starfleet officer Lieutenant Worf. A major exploration of their relationship begins with "Parallels", in which Worf encounters parallel universes where they are married with children. Another episode that explores a Troi-Worf relationship is "Eye of the Beholder". However, in both cases, they are not revealed to be dating aboard the "real" ship, although both episodes are oriented towards exploring this concept. In "All Good Things...", the beginnings of real-world relationship are briefly explored, though this is abruptly dropped as Worf explores other love interests in Star Trek: Deep Space Nine, and Troi's romantic relationship with Riker is rekindled through the Next Generation films. As a main cast member, Troi appears in nearly every TNG episode, though particular episodes, starting with "The Child", feature her as the primary protagonist. Her name is included in the show title "Ménage à Troi", which is oriented towards an adventure her mother and she have (besides Data and Q, this is one of the few cases where a character's name is in the episode title). Other episodes principally about Troi include: "Face of the Enemy", "Man of the People", "Violations", and "Night Terrors". She is addressed in various ways by fellow officers. Captain Picard calls her "Counselor", but when he is concerned about her, or in emergencies, he calls her "Deanna". Picard also refers to her as "Commander" in the pilot episode, "Encounter at Farpoint", which is consistent with her uniform's rank pips. Riker addresses her as "Lieutenant" a single time in the pilot episode; her service rank is not referred to again for several seasons. Doctor Crusher (one of her most noted female friends) usually calls her "Troi". Data very rarely calls her by her first name, usually calling her "Counselor Troi". Depending on the situation, Commander Riker calls her "Deanna" or "Imzadi", which means "beloved" in the Betazoid language. In several episodes, Troi falls victim to aliens. In an episode of season four ("Clues"), the Enterprise’s crew loses a day's memory. As events unfold, Troi is taken over by an entity to communicate with the crew. She temporarily gains "superhuman" strength and effortlessly tosses Worf across the bridge, breaking his wrist. In
