Dark Ahsoka....

During their duel, Ahsoka can see the eye of her former master Anakin Skywalker, she refuses to leave him - only for Vader to say to her ''You will die''. At this point, Ahsoka realised her chances to save Anakin were gone forever, so she duelled Vader with all the strength she had, so much so she started to feel the Dark side flowing through her, the longer the fight went on, the deeper she fell into the darkside, she was able to fight Vader and eventually killed him. After this, Ahsoka has now completely fallen to the Darkside of the force.

After Vader's death, Dark Ahsoka would make it her next mission hunt down and kill Emperor Palpatine after what he did to Anakin and the Jedi Order.
