Violations ( episode ) Several crew members suffer violent hallucinations and comas as alien researchers visit the ship . Summary . Teaser . Three Ullians , Inad , Tarmin , and Tarmin ' s son Jev have come on board . Interviewing Keiko O ' Brien in Ten Forward , Tarmin probes her memory of a cup , which she knows is important but whose context she cannot recollect . With his help , Keiko remembers that it was used by her " obachan " to wash brushes used in Japanese calligraphy . She thanks the Ullians for the pleasant memory . Tarmin attempts to persuade Dr . Crusher to undergo the probe , but is reminded by Jev that they are not to probe people without permission . Act One . Data and Geordi La Forge discuss the nature of memory while walking together in a corridor . Data is puzzled over the importance of the Ullians ' ability to retrieve memory , as he believes that if an event is important , it should not be forgotten . La Forge tells him that it is not that simple for Humans , as they cannot recall certain memories in an instant . Later , at a dinner for the Ullians with the senior staff , Tarmin describes the Ullians ' project to build an archive of memories from many worlds , calling his group " archaeologists of the mind . " However , he is stymied by the staff ' s refusal to undergo the procedure . He embarrasses his son with an anecdote of quickly retrieving a memory that Jev could not . Piqued , Jev leaves the dinner . Counselor Troi follows him , and sympathizes with him about overbearing parents . She then returns to her quarters . But while getting ready for bed , she has flashes of memory about a romantic encounter with Commander Riker . She gets a hot chocolate from her replicator to try to calm down . The memory turns unpleasant however , when he begins to force himself on her – and then turns into Jev , who also appears elsewhere in the room . She then falls into a coma . Act Two . In sickbay , Dr . Crusher and Dr . are examining Troi and bringing Riker and Picard up to date on her condition . They cannot identify the cause of the coma , standard revival techniques have failed , and Dr . Crusher does not want to attempt anything else without identifying the cause . Riker goes to speak with Jev in Ten Forward , who reacts with a certain hostility to the questions Riker poses regarding his whereabouts and the speculations about a Ullian cause for the coma . But he consents to an examination . Riker goes to sickbay to see Deanna and speaks with her , hoping she can hear him despite the coma . He remembers that she did the same for him when he was in bad shape . He is exhausted and emotional ; Dr . Crusher tells him to get some sleep . Back in his quarters , he , like Deanna , experiences flashes of memory . He is in main engineering during a containment breach ; he must order the closure of the emergency door , trapping Ensign Keller inside . A colleague of hers angrily accuses him of killing her ; this officer turns into Jev . When Picard tries to contact Riker , he does not respond ; Worf , investigating , enters his room and finds him unconscious . Act Three . Crusher has found an electropathic residue in the thalamus – the memory center – of both Troi and Riker . This suggests Iresine syndrome , but that condition is ruled out because the two patients are not showing decreased histamine levels . Worf suggests quarantining the Ullians , but Picard says no . When spoken to by Picard , Tarmin reacts with shock to the notion that the Ullians could cause the comas . Inad , however , agrees to such monitoring for the next morning . In the meantime , Dr . Crusher and Dr . Martin scan Keiko , who does not show any unusual signs , not even the electropathic residue that the others present ; and Geordi searches for agents that can cause electropathic residue , finding nothing aboard the " Enterprise " . Beverly continues to research Iresine syndrome in her office ; but as she works , she experiences the same memory flashes . In her case , she sees a younger Picard accompanying her in a morgue to see the body of her husband Jack . Picard turns into Jev , as does Jack – horrifyingly opening his eyes . In fear she turns to Picard , who is also Jev ; and lets out a frantic scream . Act Four . When La Forge and Data come to deliver La Forge ' s report to Beverly , they find her in a coma . La Forge rushes to check on her while Data signals a medical emergency to her office . As La Forge and Data report the incident to Captain Picard in his ready room , he orders Data to investigate the other planets that the Ullians have visited for unexplained comas . He also decides to restrict the Ullians to their quarters , though La Forge questions the effectiveness of this measure on telepaths . They are interrupted by the news that Troi has awakened . In sickbay , she reports that she cannot remember the circumstances of falling into the coma . The Ullians react with irritation to being asked to stay in their quarters ; even Inad reacts , asking for permission to help clear their name by conducting a memory search on Troi . Picard , despite his concern for exposing Troi to telepathy after her ordeal , agrees but will discuss the request with Troi first . Data and La Forge have not found any unexplained comas in their search ; the Epsilon Nel system has yet to report . However , La Forge suggests seeking cases of Iresine syndrome , thinking that it might have been misdiagnosed . Indeed , two cases of Iresine syndrome turn up on Hurada III while the Ullians were present . Troi agrees to the memory search , which Jev conducts . She revisits the memory that provoked her coma – but this time , Jev is replaced in her memory by Tarmin . Act Five . Jev apologizes to Picard for Tarmin ' s behavior and offers the support of the Ullian legal system . Although Picard says the Federation has no law against telepathic memory invasion , the Ullians do and the penalty is severe , even though the practice has been unheard of for centuries . Picard notes that Tarmin is maintaining his innocence . Meanwhile , Data and La Forge receive a transmission from the Nel system , reporting unexplained comas . Tarmin is cleared when they discover that he was on the Ullian homeworld at the time , between stardates 45321 and 45323 . Jev goes to visit Troi in her quarters to apologize . As he does so , however , he begins to make alarming remarks about her beauty . Abruptly , she starts to have the flashes of her previous memory . She realizes it was actually him in the memory , not Tarmin , and fights back physically . He throws her across the room , but Worf , Data , Kellogg and another security officer burst in and overpower him . Data tells Troi they have discovered that Jev , not Tarmin , was the only Ullian present at all the incidents of coma . The situation resolved , Tarmin promises the assistance of Ullian physicians , but warns that no incidences of this form of rape have occurred in over 300 years , and these physicians might be somewhat out of practice . Tarmin himself is badly shaken by the thought that any Ullian , much less his own son , could have committed acts that have not been known since a dark time in Ullian history was resolved . Picard notes that , although Earth experienced such times and is now peaceful , it is important for both Humans and Ullians to recognize that the seed of violence remains within all of them . To forget that is to risk allowing such a seed to grow and consume them , as it did Jev . Memorable quotes . " " How about you , commander ? Got any memories you feel like digging up ? " " " " None that I ' d care to share with an audience . " " " " What is the last thing you do remember ? " " " " My hair . I was brushing my hair . " " " " Klingons do not allow themselves to be . . . probed . " " " " I miss you . Please don ' t stay away too long . " " " " I ' m not implying that you did anything intentional . I ' m just trying to get to the bottom of the mystery . " " " " We have nothing to hide . If you wish to spend time examining us . . . " " " " Fine . Thank you . " " " " It ' s not easy having an overbearing parent , believe me , I know how you feel . " " " " I ' ve learned to remind myself that my mother and I are two separate individuals . " " " " Mm - hmm . And have you enjoyed much success with this approach , counselor ? " " " " No . But I do keep reminding myself . " " " " I ' ve heard doctors say that even when someone ' s in a coma , they may be able to hear when people talk to them . . . that it might help stimulate the brain and speed the healing . In fact , I think you did that for me once , when I was in pretty bad shape . " " " " Why do you have to be so nice ? So . . . so lovely . " " " " But I think no one can deny that the seed of violence remains within each of us . We must recognize that , because that violence is capable of consuming each of us , as it consumed your son .
