Slick is the clone sergeant unmasked as a Separatist informer in The Clone Wars' first-season episode "The Hidden Enemy", broadcast in February 2009. He is voiced by Dee Bradley Baker.
His interrogation is the moment the series declares what it is going to be about. Asked why, Slick says Asajj Ventress offered him something money could not: freedom. He argues that the clones are slaves of the Republic and the Jedi, that his brothers died for a war they did not choose, and that his betrayal was a blow struck on their behalf. The Jedi have no answer, because there is not one, and the show spends six more seasons circling the hole he opened.
