Around 22 BBY, the Tango Company was sent to fight in the Second Battle of Geonosis. After the battle, they slept outside their transport. While sleeping, Scythe was infected by a brain worm controlled by the Geonosian hive queen that had found its way to the surface. Undetected, Tango Company boarded a Pelta-class frigate and traveled towards the Ord Cestus medical station, where they had to run a medical errand. While flying, Scythe infected the other clones, but was unsuccessful with infecting the two Jedi Padawans traveling with them. Ahsoka Tano and Barriss Offee escaped their grasp, until Offee was cornered and forced to take in the brain worm.
With a Jedi at their side, Tango Company hunted down the last Padawan and killed the pilots, taking control of the ship. Before taken down, Ahsoka Tano contacted Jedi Master Kit Fisto on the station, informing him of her troubles. He told her to make the ship cold, and it would paralyze the brain worms. She did what he said, and the brain worms started to die down. Just as they got to the station, all the members, save for Trap who was killed, on board were knocked unconscious. They woke up in the station without any brain worms and back to original form.
