Ahsoka delivered the moment Star Wars fans had been waiting for in Episode 5, when Rosario Dawson's Ahsoka Tano found herself face to face with Hayden Christensen's Anakin Skywalker. The two Jedi -- a master and an apprentice -- have a long history together in animation on both Star Wars: The Clone Wars and Star Wars Rebels. However, Ahsoka marked the first time they had been seen together in live-action. The reunion occurred when Ahsoka was seemingly killed in her duel with Baylan Skoll, awaking to find herself in the World Between Worlds, where Anakin was able to manifest before her.
