c. 32 BBY
After the Second Battle of Geonosis, Jedi Padawans Ahsoka Tano and Barriss Offee was ordered to to pick up medical supplies from a medical station above Ord Cestus. Pulsar and the rest of Tango Company went with them. While sleeping near the Progate Temple, one of the troopers, Scythe was infected by Geonosian brain worms. The company was woken up by their Lieutenant, Trap, and left Geonosis in a medical frigate. On board, Scythe infected the other clones and later Barriss. He was later seen being affected by the cold, when Ahsoka ruptured the coolant system to kill the worms. He and the remaining members of Tango Company were soon stabilized.
