But Ventress survives Dooku’s assassination attempt, and the jilted former apprentice vows to take revenge, enlisting the aid of her kinswomen – the mystical Nightsisters of Dathomir – in her sinister scheme. Evil clashes with evil and sparks fly – igniting the fuse for the launch of the explosive second half of Star Wars: The Clone Wars Season Three. Darkness falls and the end begins with “Nightsisters,” an all-new episode debuting at an ALL-NEW TIME – 8:30 p.m. ET/PT Friday, January 7 on Cartoon Network.
