Billaba informed the Kallerans that the Separatists would no longer trouble them , but the natives claimed they saw no difference between Separatist and Republic occupation . Dume , Styles and the Commander became angry at the Kallerans , but Billaba remained calm and informed Key that the Republic forces would spend the night in fields nearby . While camping later that night , the two clones and the two Jedi sat together and discussed why Billaba had not said anything to the Kallerans who compared the Republic and the Confederacy . Grey and Styles strongly disagreed when Billaba said she did not agree with Jedi taking up the rank of general , but were amused when they learned Dume had been infamous for asking to many questions during his time at the Jedi Temple on the planet Coruscant . During the discussion , Grey was contacted by Supreme Chancellor Sheev Palpatine and told to commence Order 66 , the execution of the Jedi .

After a job gone wrong resulted in the pair getting caught , Kasmir immediately sold out the fact that Dume was secretly the escaped Jedi Padawan , and seemingly traded him to Gamut Key ' s security in exchange for his escape . Grey and Styles were able to confirm for Key that the boy was , in fact , the Padawan they had been hunting for , and they ordered the Kalleran to hold him in a cell until they could leave the Imperial Garrison at Plateau City to take him in and execute him for treason within the hour . Shortly after their message , however , Kasmir had a change of heart and broke Dume out of his cell , escaping Kaller and intending to travel planet to planet across the Outer Rim .

While he was unable to convince the clones not to kill him , Caleb did manage to buy enough time for Kasmir and Kleeve to catch up to the Imperial freighter . Caleb Force push ed the clones and remotely activated the airlock , escaping into the vacuum outside . After managing to return to the bridge of the freighter , Grey began to have doubts . Despite having sufficient firepower to destroy both the Kasmiri and " Farbrooke ' s Hope " , Grey could not help but wonder why the clones had so blindly obeyed Order 66 . He brought his concerns up with Styles who disagreed , seeing Caleb only as a traitor to the Empire .
