Plan of Dissent " Plan of Dissent " is the ninth episode of the . It aired on November 11 , 2011 . Official description . " " After the Republic conquers an Umbaran airbase , General Krell orders Rex and his men on towards the heavily fortified capital . Realizing there ' s a better plan , several clone trooper s disobey orders to carry out a rogue , covert operation . " " Synopsis . While the clone trooper s prepare to secure the airbase , Obi - Wan Kenobi calls in with further bad news , as his own forces are pushed back by long - range missile fire and the Umbara n forces , deprived of their airbase , are now being resupplied by a support ship guarded by a strong fleet contingent . Before he can give more information , the Umbarans jam the transmission , whereupon Krell decides to march directly to the capital city to end the war on this planet , dismissing any attempt to re - contact Obi - Wan and coordinate a joint attack , as Rex tries to suggest . When Rex briefs his men about the impending new mission , the troopers begin to argue amongst themselves . Some , including Rex ( if reluctantly ) and Dogma , maintain their loyalty to Krell as a Jedi General , but others – especially Fives and Jesse – openly question his military competence , which is obviously clouded by his own stubbornness and lack of regard for his men . While discussing the dilemma with Rex , Fives informs the Captain that the clones have access to the Umbaran fighters and access codes , giving them the capability to sneak past enemy defenses undetected . Rex is persuaded , and forwards the plan to Krell , but the Besalisk Jedi refuses to " waste " any men on what he calls " frivolous adventures . " A disappointed Rex relays the news to the squad , however Fives insists that they go on with the sneak attack nevertheless . This begins to create friction among the squad , with most of the clones agreeing with Fives , with the notable exception of Dogma , who grows suspicious of his dissenting brothers . After leaving the barracks , Fives confronts Rex , challenging him for standing for Krell ' s plan . Though visibly conflicted , Rex attempts to convince Fives that they are honor bound to follow their orders , and consider themselves as part of the greater picture , without questioning . Growing frustrated with Rex , Fives insists that he cannot follow orders that he knows are wrong , and allow others to suffer as a result . Fives breaks off the conversation , stating that he intends to find accomplices for his plan , leaving Rex increasingly disturbed and torn . In the hangar , Fives and Hardcase attempt a sneak crash course with one of the Umbaran fighters . However , the practice run literally becomes a crash when the fighter proves too hard to control for Hardcase , causing damage and disruption to the facility . Finally , one of their fellow troopers and a missile accidentally fired by Hardcase give the game away . Fives and Hardcase just barely manage to explain the mayhem away with a booby trap left in the fighter ’ s programming , but this only serves to reinforce Krell ’ s argument that the fighter infiltration mission will lead to disaster , and he officially discards the plan , prompting Rex to eye the dissenters with exasperation . Despite the setback , Fives , Hardcase , and Jesse decide to go through with their scheme nevertheless . Fives lays out a plan to attack the supply ship ’ s main reactor from the inside , recalling that as a boy , Anakin Skywalker had performed the same tactic before . Before they leave , Fives alerts Rex , giving him one last chance to order them to stop . Instead , Rex implicitly gives his approval , but warns that he will not cover for them , when they are caught . The rogue troopers commandeer three of the Umbaran fighters and take off towards the supply fleet . In the meantime , Dogma notices that Fives and his cohorts are not in the barracks and convinces Tup to join him in alerting General Krell , warning him that to not do so would make them complicit in the crime . Meanwhile , Krell ( who is as yet unaware of the true situation ) proceeds to reprimand Rex about the unauthorized start of the fighters . Despite his earlier warning to Fives , Rex cunningly explains that the fighters were launched for a reconnaissance mission for the upcoming assault on the capital , allaying Krell ’ s suspicions for the moment , but then he spots Dogma and Tup attempting to make their way to Krell and manages to turn them away at the last moment . Fives , Hardcase and Jesse arrive at their target , but only to find the supply fleet under heavy attack from Republican space forces . They manage to sneak their way into the supply ship ’ s main hangar , but a battle droid eventually discovers the pilots ’ true nature and raises the alarm . The reactor is put on ray shield s immediately , foiling the clones ’ attempt to blast them and leaving them to face an approaching droid interception force . Hardcase spontaneously detaches a missile pod from his fighter and , exiting his vessel , guides it by hand into the reactor system , sacrificing himself to ensure the mission ’ s success . Fives and Jesse make a daring escape from the exploding ship , while Rex and Tup watch the explosion from the ground , prompting a proud smile from Rex . Fives and Jesse make it back to the airbase , where they , Rex and Tup share a brief moment of remembrance for Hardcase ’ s passing . The squad is confronted by Appo and a few other troopers , who inform Rex that the rogue clones are to be taken to Krell . In order to protect Fives and Jesse , Rex attempts to take the blame upon himself , whereupon Fives attempts to do the same in favor of Rex . But Krell proves unforgiving in any case and promises harshly to have both Fives and Jesse court - martialed and executed for their ' act of insubordination ' . Behind the scenes . In a scene outside the Umbaran airbase , when Fives , Jesse and Hardcase approached Rex to inform him of their plan , Jesse was standing on Fives ' right while Hardcase was on his left in one shot . In the next shot their positions were swapped . Also , in the flight scene with Fives , Jesse , and Hardcase , Jesse expresses his discomfort , but when Fives replies , he says " Hardcase , " not " Jesse " In the last scene , the markings on Jesse ' s helmet were missing in one shot . A reference to " A New Hope " is present in this episode when Krell demands to know which clone he ' s speaking to with the words " Who is this ? What ' s your CT number ? " . This mirrors the famous exchange Han Solo has with an Imperial officer after the firefight in the Death Star ' s detention block .
