" TB - 73 " was used by the Republic Navy around the year 22 BBY . It was sent to Geonosis following the previous conflict . There , Padawans Ahsoka Tano , Barriss Offee and Tango Company were stationed aboard the ship during a medical supply run to a station near planet Ord Cestus . Unknown to the Jedi was that company member CT - 9544 had been infected with a brain worm and was carrying eggs to infect all that were aboard . " TB - 73 " took off from Geonosis and went into hyperspace . While in hyperspace , trooper Scythe planted the eggs and infected some troopers in their quarters while they lay asleep . The brain worms quickly gained control and soon all troopers were infected . The infected clones then began to take over the ship , killing the pilots and attempting to kill the two Jedi who were eating in the mess hall . The troopers in the bridge set the ship to autopilot and put all of the shields up preventing Ahsoka and Barriss from reaching the bridge . The two Jedi began to move through the vent system of the ship and decided to split up to reach the reactor room and the communications station . Barriss was caught by an electric trap just short of the reactors and also got infected by the clones . Ahsoka reached the comms station and contacted Jedi Master Kit Fisto , sharing the horrifying news with him . She then turned to find an infected Barriss Offee waiting for her . The two began a duel the young Padawan escaped from through the air ducts . After contacting Anakin Skywalker and finding out that the brain worms die in cold , Ahsoka went to " TB - 73 ' s " cooling units and ruptured them , opening up a freezing fog . The brain worms began to die within the troopers and Ahsoka found her way to the bridge just as " TB - 73 " left hyperspace . She began to take control of the ship when Barriss attacked her again . They cut open one of the coolant tubes , which Ahsoka blasted into Barriss ' s face . The worm began flailing around in Barriss ' s mouth as she slowly came out of the trance . Meanwhile , two tugboats were attempting to dock " TB - 73 " into the space station and finally succeeded . Kit Fisto and his team quickly boarded the ship and found Barriss and Ahsoka covered in frost on the cockpit floor .
