Rooney ( 22nd century ) Rooney was a researcher with the Earth Sciences Institute and was a member of the A - 6 excavation team , the Arctic Archaeology Team , in 2153 . That year , the team journeyed to the Arctic Circle in the Arctic on Earth . After they arrived aboard the transport " Arctic One " , they found the debris of an alien ship . Rooney , and Moninger also found the body of a Borg drone , concealed under ice . A short time later , Rooney found another body under the snow . The team decided to build a base camp to study the two Borg drones and also the fragments of the alien ship . Rooney scanned several of the debris pieces and found proof , inside the glacier , that these pieces were over 100 years old . Later outside , Rooney discovered the ship ' s transwarp coil while talking to Drake . The two went back to the research module when they heard screams and saw the fire of a phaser rifle . They found Moninger inside the module , under some equipment . When Rooney turned around to get a medical kit , she almost ran into a Borg drone . Assimilated by the Borg , Rooney herself became a Borg drone . Aboard the assimilated " Arctic One " , she tried to stop Captain Jonathan Archer and Lieutenant Malcolm Reed , an away team from , but was fired upon with a phase - pistol . Archer then identified her as one of the researchers from the arctic team . Like all the other Borg , she was later destroyed when " Enterprise " fired on the transport and thereby destroyed it . ( ) Background information . Rooney was played by actress Bonita Friedericy , wife to actor John Billingsley . In the script for " Regeneration " , Rooney was described as an engineer in her thirties , during the events of the story . In an audio commentary for " Regeneration " on ENT Season 2 Blu - ray , Bonita Friedericy and John Billingsley joked that Friedericy got the part of Rooney by sleeping with Tucker actor Connor Trinneer . In reality , Friedericy auditioned for the role of Rooney , but when she walked into the room to audition , creators and Executive Producers Rick Berman and Brannon Braga pretended not to know her . " " It was very unnerving , because I ' m very shy and I didn ' t know whether I should say hello or not , " " Friedericy explained . " " So , I sort of waved at them and they both kind of looked distastefully at me , and looked up at the ceiling and then they said , ' Go , ' and I thought I wasn ' t gonna get it , and it was sad , but then I got the call and I got it . " " For a scene in which Rooney is at a console in the background , Friedericy tried to make it seem as if her character was as busy as possible , without becoming distracting for the audience . She also tried to imply subtext that Rooney was having an affair with Drake . On the set , Bonita Friedericy was referred to as a Borg baby . " " I was called the baby Borg because Borg are never little , and I ' m five - foot - three , " " she remarked . Applying the Borg makeup to Friedericy for Rooney ' s assimilated appearance took five - and - a - half hours . This was longer than usual because the makeup team , not having done any Borg for a while , initially made a mistake with Rooney ' s Borg makeup . To portray the assimilated Rooney , Friedericy also wore a Borg costume that Roxann Dawson had previously wore , in . Once Friedericy was made to look Borg , it was time for her to go before the cameras as the assimilated Rooney . Filming the character ' s death scene didn ' t require a stunt performer . " " I was really pleased with myself , " " she reminisced , " " because they squibbed me [ repeatedly ] , and I did my own stunt . " " Each time Friedericy performed the stunt sequence , John Billingsley applauded her from off - camera . ( ENT Season 2 Blu - ray , " Regeneration " audio commentary ) Her arctic archaeology team coat from " Regeneration " was later sold off on the It ' s A Wrap ! sale and auction on eBay . Her Borg costume was sold off at the " " auction at Christie ' s .
