Author's Notes: I worked on this now, as we had around 160 people viewing this, as of May 20th 2021. I'm so impressed, as I didn't think this Dark!Ahsoka story would do so well.
Anakin rewatches the video, looking for a trace of blue in her golden eyes. There's no blue.
Is it really too late for my former Padawan? Have I been wrong all these years?
A while later
A new video shows up on his datapad. He presses play on the video. The video starts, "Hello, Anakin. I just helped get rid of the Rebel cell on Taris. Tons of fun, you know. Your pathetic rebellion will die. I still plan on offing Palpatine, just due to some attacks by your rebellion, which made him paranoid, it'll just have to wait a few months. Same warning as first video, Je- Anakin." There is still no blue in her eyes, just unending gold. Was I wrong? Is it too late for Ahsoka to re-emerge from beneath the mask of Darth Saph? Is it too late for her? Is Ahsoka still hiding behind the mask?
Flashback
Mustafar
Anakin says, "This isn't you, Ahsoka." He doesn't really want to fight his former Padawan, but he will if he must. If she' s fallen to the dark side.
"Ahsoka Tano is dead, and I now feel better than I ever had. Even better than Mortis!" Her eyes are pure gold, with not a speck of blue left. She ignited her twin lightsabers, still green, as she hasn't had enough time to break the crystals to her will. The will of the dark.
Anakin ignited his blue lightsaber, and the two dueled. Anakin was trying to just maim Ahsoka, while Ahsoka was trying to kill.
A little while later...
Even with Ahsoka's dark powers, she knew she couldn't win. Then, she missed a blow. Anakin, with one swoop of his blade, destroyed her main saber, and cut off her left arm, then destroyed her shoto saber. She collapsed, and Anakin walked away.
