A chip did malfunction before during Star Wars: The Clone Wars, nearly exposing Order 66 to the Jedi. The clone trooper Tup went rogue when his chip activated Order 66 early, killing his Jedi general. Another clone trooper, Fives, dug into the mystery and had his chip removed. He was ultimately killed, and Order 66 remained secret, but the ordeal proved two things: the chips weren’t infallible and the clones could think for themselves about Order 66. Does this mean that some clones are able to resist carrying out Order 66?
