Kila Marr Doctor Kila Marr was a Human xenologist and former resident of the Omicron Theta colony . She had one son , Raymond , born in 2322 . Prior to 2338 , Dr . Marr left the colony to pursue her career and left her son , nicknamed " Renny , " in the care of the Wallace family , friends who remained in the colony . Although she kept in contact , Marr never found the time to return to the colony before Renny was killed in an attack by the Crystalline Entity in 2338 . Dr . Marr experienced a great amount of guilt over the fact that she did not make it a priority to visit her son , and channeled her feelings into studying the Entity and examining its attack sites . By 2368 , Marr was renowned as the foremost expert on the Entity . She studied at least three different attack sites , including one at Forlat III , and also developed a method to modify photon torpedo es in order to destroy the Entity . That year , she visited the following an attack on Melona IV . Marr was excited , as this was the first opportunity to examine a site so soon after an attack . She also wanted to interview the survivors as no one had ever escaped the Entity before . She was suspicious of Lieutenant Commander Data , who was on Melona IV during the attack , and believed that the Entity spared the colonists because of his presence . Furthermore , she thought Data was in collusion with the Entity just as his brother , Lore , had been responsible for leading the Entity to Omicron Theta . Eventually , Marr began to warm to Data after Captain Picard forced her to work with him in order to develop a way to track the Entity . Together , they discovered that the creature left residual antiproton s as it moved through space . The " Enterprise " - D set course to pursue the Entity after it was located and Marr wanted to make preparations to destroy it once it was found . Captain Picard objected , feeling it would be better to try to communicate with the Entity and attempt to reason with it before resorting to violence . Marr vehemently disagreed with this plan , as she felt that the Entity was no more than a " killing machine " and was beyond redemption . She reluctantly agreed to work with Data again , this time to develop a way to use graviton pulses as a means of communication . By this time , Marr had apologized to Data and realized that she was presumptuous in accusing him of leading the Entity to the Melona colony . She also learned that Data contained some of Renny ' s memories , experiences , and journal entries ( which had been programmed into Data as an attempt to allow him to better interact with Humans ) and used Data ' s knowledge to learn more about Renny , most importantly that he did not blame her for leaving him on the colony . Shortly following , the " Enterprise " - D responded to a distress call from the freighter " Kallisko " , which was attacked by the Entity and had all organic matter on board , including its crew , absorbed . The incident with the " Kallisko " made Marr think further about Renny and wonder about his final moments . Eventually , she had Data tell her more about Renny and even read one of his journal entries in his voice . The entry was especially poignant as it took the form of a letter to Dr . Marr , where Renny discussed a recent test and said that he missed her a great deal . The " Enterprise " - D eventually caught up to the Crystalline Entity and began emitting graviton pulses in an attempt to communicate . The pulses worked , and the Entity began responding with a series of its own pulses . However , Marr , blinded by vengeance and remorse over Renny ' s death , initiated a continuous graviton beam and then locked out the controls . The beam caused the Entity to vibrate rapidly and eventually shatter , destroying it . The " Enterprise " - D bridge crew were aghast and Picard ordered Marr confined to her quarters . Data escorted her there , and Marr again wanted Data to take on the voice of Renny . She specifically wanted him to tell her that he understood why Marr had destroyed the Entity , and that he was now at peace . However , Data was unable to comply with her request . His knowledge of Renny made it clear that he had always been proud of his mother ' s life as a scientist , and that he would have been disappointed and upset that his mother had ruined her career . Marr was left to contemplate the consequences of her actions . ( )
