The episode you’re probably thinking of is “Conspiracy” from The Clone Wars Season 6, where the inhibitor chip plot is introduced. The specific Dooku-related episode that often gets mixed in is “Dooku Captured” from Season 1, but that one is about pirates holding Dooku hostage, not the behavior chip.

Why this gets mixed up

The clone “behavior chip” storyline is tied to the later Season 6 arc about Fives and the chips, not to Dooku himself. The chip concept is first identified in “Conspiracy” , then develops through the surrounding episodes in that arc.

Dooku episode

If your memory is of Dooku being physically held captive, that’s “Dooku Captured.” In that episode, Hondo Ohnaka and pirates hold him for ransom.

Fast answer

  • Behavior chip episode: “Conspiracy”.
  • Dooku held captive episode: “Dooku Captured”.

TL;DR: The clone chip story is “Conspiracy,” while Dooku being held by pirates is “Dooku Captured.”
