Years later, Ahsoka is a Rebel operative and suggested to seek out Captain Rex, who possessed extensive knowledge of the Outer Rim which would help the Rebels find safe havens to build a hidden base of operations at.
Rex, who removed his control chip, managed to fake his and Ahsoka's deaths, who subsequently separated and went into hiding. They almost succeeded when Order 66 came down from Coruscant. Ahsoka was appointed by the Republic to lead Captain Rex and a detachment of the 501st to capture Darth Maul at Mandalore.
