Jester presents his freshly scrubbed weapon to Cody.
When the battle droids discovered a crippled Christophsian and discussed killing the man, the clones intervened and eliminated the droids before returning to the base.[8] Later, Sergeant Slick's platoon was stationed in the South tower with General Kenobi and Clone CommanderCC-2224, while Skywalker and Clone CaptainCT-7567 were based with their troopers in the parallel North tower. The Republic troops prepared to attack the Confederate droids below, but the approaching droid column unexpectedly split in two, and battle droids arrived in the South tower and ambushed the clones. Skywalker and his men arrived in the South tower to reinforce Kenobi's group, and taking a turbolift to the roof of the tower, the Republic forces escaped in clone pilotHawk'sLAAT/i gunship.[3]
After the Republic forces had returned to their base, Jester cleaned his DC-15S blaster, as he always did after a battle. During investigations regarding the possibility of a Confederate spy amongst their ranks, CC-2224 and CT-7567—nicknamed "Cody" and "Rex," respectively—traced an irregular wavelength in external communications to Slick's barracks. Suspecting that one of the sergeant's men was the turncoat, the two clone officers called the unit to individually interrogate them in the platoon's quarters. Jester was initially nervous about speaking to his commanding officers, but fellow trooper Sketch vouched for him, and Jester presented his freshly scrubbed weapon to Cody as proof. Eventually, Slick was revealed to be the spy, and escaped before severely damaging the Republic's gunships, AT-TE walkers, and weapons depot. The turncoat sergeant was spotted running into the base's command center, and Rex and Cody ordered Slick's platoon to secure the perimeter. The two clone officers later managed to apprehend the traitorous Slick.[3]
Jester and his brethren discover Slick's treachery.
Combat taught Jester the value of his blaster, and the self-disciplined trooper developed a habit of cleaning, scrubbing, and maintaining[1] his weapon after every battle. He was initially nervous about talking to his commanding officers, and at first stuttered while addressing Rex and Cody[3]—in his opinion, he would have rather faced a horde of battle droids than be confronted by his superior officers during an interrogation.[1] After Sketch vouched for him, he became more confident, offering evidence that Cody and Rex could verify themselves. Jester was visibly shocked when his own sergeant, Slick, was revealed to be the traitor.[3] Besides maintaining his weapon, Jester kept his sideburns carefully tended. In addition to being trained in combat, recon, and military tactics, he was proficient in handling heavy weapons like the Z-6 rotary blaster cannon.[1]
