Recap / Star Wars: The Clone Wars S2E8 "Brain Invaders"

Go To

Attachment is not compassion.

The Republic is still clearing up Geonosis, although the planet has been mostly subdued. Master Ki-Adi-Mundi informs Obi-Wan Kenobi, Luminara Unduli, and Anakin Skywalker that Master Mace Windu's forces on Dantooine urgently need medical supplies. However, Anakin, Obi-Wan, and Luminara have to transport the captured Geonosian leader Poggle the Lesser to Coruscant. Therefore, Padawans Ahsoka Tano and Barriss Offee are sent to collect the supplies from the medical station near Ord Cestus, with the older Jedi joining them after they've delivered Poggle. They leave with a full detachment of clone troopers — but there's a problem. One of the clones was infested with a Geonosian brain worm while sleeping, and now he's got a backpack full of them...



  • Air-Vent Passageway: Ahsoka and Barriss take to the ducts while evading the possessed clone troopers.
  • Bald of Evil: Scythe, the first trooper to be infected and the one who brings the brain worm eggs onboard the frigate, has a shaved head, although presumably he doesn't normally qualify.
  • Call-Back: After two possessed clones attack Ahsoka and Barriss in the mess hall, Ahsoka mentions that her master had a clone trooper betray him once.
  • Call-Forward:
    • Mind-controlled clone troopers attacking Jedi? It sounds exactly like something that will eventually happen towards the end of the war. When Barriss is captured, one trooper even says this:
      "If there's one thing we clones know, it's how to stop a Jedi."
    • When Anakin starts Force-choking Poggle, the Imperial March is heard in the background.
  • Dying as Yourself: On the freezing ship, when Barriss manages to get a moment of clarity, she asks Ahsoka to kill her. Ahsoka declines.

  • Force-Choke: Anakin does this to Poggle while interrogating him on a way to stop the parasites, after learning that mind tricks won't work.
  • Foreshadowing:
    • The clone troopers are mind-controlled by parasites in their brains and attack the Jedi. It's later revealed this is similar to how Order 66 functions.
    • There are several elements of Barriss' actions, both before and after she's infected with a parasite, that hint at what she will do in season five.
  • "I Know You're in There Somewhere" Fight: Ahsoka attempts this with the possessed Barriss, but it doesn't work until after Ahsoka ruptures the coolant system, dropping the temperature.
  • Impaled with Extreme Prejudice: Barriss kills Lieutenant Trap in self-defence by igniting her lightsaber through his torso.
  • Jack Bauer Interrogation Technique: Implied to be what Anakin did to Poggle to get him to spill about how to defeat the brain worms.
  • Advertisement:
  • Kill It with Ice: Ahsoka lowers the temperature by rupturing the coolant system, disabling the possessed clones. It takes longer for Barriss to succumb, as Mirialans are more resistant to the cold due to hailing from a cold planet.
  • Let's Split Up, Gang: Barriss suggests that she go disable the thrusters, while Ahsoka tries to warn the fleet. Ahsoka has reservations, but goes along with it — and because they split up, Barriss is caught and infected.
  • Logical Weakness: The brain worms are from Geonosis, a hot desert planet. They're vulnerable to the cold.
  • Murder Is the Best Solution: Barriss definitely kills one possessed clone and might have killed another — whereas Ahsoka is clearly taking much greater care to avoid killing any of them.
  • No-Sell: As Poggle informs Anakin via a translator droid, Geonosians have a natural immunity to Jedi mind tricks.
  • Puppeteer Parasite: The Geonosian brain worms are confirmed to be able to control other species, and even Jedi (well, a Padawan, at least).
  • Scream Discretion Shot: When Barriss is captured and infected with a brain worm, her scream is cut off by a force-field going up.
  • Sleep Cute: Ahsoka and Barriss do this in the cockpit while freezing after Barriss has been freed of her brain worm.
  • Tractor Beam: Two tugboats using these slow the frigate down after it drops out of hyperspace.
