At first, Ahsoka has no idea that Anakin Skywalker and Darth Vader are one and the same. She discovers the truth in Star Wars Rebels when she encounters the Sith Lord in a space battle. What she senses is so shocking to her that she passes out.
As things unfold in the Siege of Mandalore arc, Ahsoka can feel Anakin's pain through the Force as he saves Palpatine and turns to the dark side. While she doesn't know what specifically transpired on Coruscant, Ahsoka can sense that something terrible happened to her friend.
Ahsoka survived Order 66 thanks to Anakin's training and sensed his fall to the dark side, which ultimately led to her confrontation with Darth Vader years later.
This isn't the first time Ahsoka has studied one of these recordings, as she viewed one used by Ezra Bridger in Star Wars Rebels season 2 through a holocron. Ahsoka choosing to remember Anakin as he was before he fell to the dark side reaffirms that Darth Vader is dead in Ahsoka.
She certainly knew something. The “I know. More than you realize, I know” line makes that clear, as does the Forces of Destiny short with Anakin, Padme, and Ashoka.
Anakin does not have even the slightest bit of remorse. By the end, he feels nothing but anger. Although he feels regret for killing Padme, he still helps the evil Emperor. The film ends with Anakins standing side by side with the man on whose behalf he has committed all his crimes.
Does Ahsoka find out about Anakin being Darth Vader?
She discovers the truth in Star Wars Rebels when she encounters the Sith Lord in a space battle. What she senses is so shocking to her that she passes out. Snips has her suspicions confirmed when she comes face to face with Vader in the Rebels season 2 finale, in a Sith Temple on the planet Malachor.
While the Star Wars canon doesn't explicitly confirm his regret, the intricacies of his relationship with Ahsoka and the remnants of his former identity could have stirred some degree of internal turmoil.
Tales of the Jedi raises an interesting question about Darth Vader's morality and motivations during the rise of the Empire, suggesting he knew of Ahsoka Tano's survival after Order 66 but kept it hidden from the Empire.
How did Ahsoka know about Anakin and Padmé are having secret marriage in their relationship? Ahsoka is often seen accompanying Anakin interacting with Padmé, so it's evident that she would know of it. She also reaffirmed this during the scene she left the Jedi Order.
Anakin Skywalker showdown would end in Ahsoka's favor. It is likely that, at the peak of his power, Anakin Skywalker would always have bested his old Padawan.
But in season five of The Clone Wars, Barriss betrayed Ahsoka and framed her for a crime she did not commit. On the Star Wars show, Barriss became disillusioned with the Jedi's role in the ongoing wars. She believed leading an army into battle was a betrayal of their principles.
Ahsoka's portrayal of Anakin with a red lightsaber fulfills the promise that Revenge of the Sith couldn't deliver, showcasing the version of Anakin who would become the most powerful being in the galaxy.
Summary. A disturbing theory suggests that Darth Vader kept one of Ahsoka Tano's lightsabers for a darker reason, potentially using its kyber crystal to improve his own blade.
Anakin Skywalker's villainous alter ego, Darth Vader, appears in Ahsoka Episode 5, "Shadow Warrior." The events of Ahsoka Episode 5 suggest Darth Vader's spirit could still live in Anakin Skywalker. Anakin Skywalker could be paying for his sins as Darth Vader as a Force Ghost.
Darth Vader hesitated because he was very suprised that ahsoka was alive because she was assumed dead when He found her lightsabers on the remote moon were they crashed the Venator where many clones died being controlled.
In Star Wars Rebels, Ahsoka Tano crosses lightsabers with her former Jedi mentor, Anakin Skywalker — or what's left of him anyway. When Star Wars: The Clone Wars ended its original run, Ahsoka sees Anakin for the last time when she walks away from the Jedi Order.
What happened to Ahsoka after Anakin became Darth Vader?
As the events of The Revenge of the Sith played out and Anakin turned to the Dark Side and became Darth Vader, The Clone Wars series showed that Ahsoka was off fighting to retake the planet Mandalore from Darth Maul, who was revealed in the show to have survived his seemingly fatal duel with Obi-Wan Kenobi on Naboo.
The canonical comic Star Wars: Darth Vader #7 confirms the younglings' deaths caused Anakin grief, self-loathing, hatred, and pain, fueling his descent even further into the Dark Side.
Ahsoka's departure haunted Yoda for a long time; he felt extremely guilty and remorseful, partly for refusing to stand by her and partly for placing her on the path that led to her departure from the Order. In fact, his guilt was so great that the Dark Side attempted to use it against him, but failed.
Desperate to clear her name, Ahsoka was captured, stripped of her Padawan status, and expelled from the Jedi Order. Her Master Anakin Skywalker, however, never stopped believing in his apprentice's innocence and uncovered the truth: Jedi Barriss Offee, Ahsoka's friend, was the real culprit.
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
Instead, the diminutive droid appears to have kept his own counsel, perhaps wary of interfering too much in Luke's personal journey. C-3PO lost those memories, but he remained with Han and Leia's family after Return of the Jedi, so can reasonably be assumed to have learned the truth by eavesdropping.
Unfortunately, Rex and Vader never meet again though. Why didn't Palpatine feel afraid of showing his evil actions, behaviors and ways to Anakin and the Jedi anymore?
