Force Ghosts only speak when a Jedi needs guidance, and since Anakin didn't say anything to Ahsoka, she no longer needed his help. It represents Anakin passing the torch to Ahsoka, as his story received closure thanks to their meeting in the World Between Worlds.
When Anakin was redeemed upon saving Luke in Return of the Jedi, his "... inner person would go back to where we left it off." Additionally, Lucas thought replacing the original Anakin Force Ghost with Christensen would help connect the prequels and originals, bringing it full circle.
However, it was the appearance of Anakin's Force Ghost in the Ahsoka finale's closing moments which confirmed, yes, that really was him she'd been reunited with.
Yup. Anakin's vision of Padme's death is the main catalyst behind Anakin turning to the dark side. Ahsoka staying or leaving is irrelevant next to Anakin's unhealthy attachment to Padme.
If it really is Anakin's duty as the Chosen One to keep the balance of the Force, then it makes sense why he still watches over Ahsoka: because of her connection to the Daughter and the light side of the Force.
The Ending of Ahsoka FULLY EXPLAINED - DID YOU SEE IT?
Why does Anakin have a red lightsaber in Ahsoka?
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.
After the Clone Wars and Order 66, Darth Vader always knew his former apprentice Ahsoka Tano was alive and that he would one day face her in battle - long before it happened in Star Wars Rebels. Ahsoka Tano unwittingly played a crucial role in Anakin Skywalker's fall to the dark side.
Anakin Skywalker's Padawan during the Clone Wars, Ahsoka survived Order 66 and became a key agent in the nascent Rebel Alliance. Ahsoka began to suspect the truth about Darth Vader in Star Wars Rebels season 2, and her worst fears were confirmed when she confronted the Sith Lord in the dramatic finale.
After her recent interaction with Anakin (who is now a Force Ghost/God) in the World Between Worlds, Ahsoka learned some valuable lessons. This helped her to embrace her true self, and accept that she's not just Ahsoka. She's Ahsoka and the Daughter.
Ahsoka survived Order 66, although the capital ship she was on crashed on a snowy planet. She left her one of her lightsabers behind - a blade that had been returned to her by Anakin himself.
Yes. In Truce at Bakura, Anakin's ghost appeared to Leia, begging for her forgiveness. She rejected him. Only by Tatooine Ghost did she start to come around to the father underneath the suit, just in time for her to finally have kids in the Thrawn Trilogy.
And they forgave Anakin. The ideas of the smiling heavenly force ghost of Anakin next to Obi Wan watching over Luke or Kylo being portrayed as a finally good person before his death obviously did not bother the writers.
According to official tie-ins, Anakin's Force Ghost would visit Luke many times over the next decade, offering him guidance and counsel as he reestablished the Jedi Order.
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.
Yoda. Yoda's knowledge of Luke Skywalker's true parentage was also confirmed in Return of the Jedi. As with Obi-Wan, Yoda believed that Anakin's fall to the dark side made him unsalvageable, with the Darth Vader persona being his only identity following his ascension to Sith Lordship.
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.
But before the battle for Coruscant, they had to split up and Rex went with Ahsoka to Mandalore, and Anakin went to Coruscant. After that, Anakin and Rex never saw each other again.
Summary. A new Star Wars theory suggests that Darth Vader couldn't have killed Ahsoka Tano, and the upcoming Ahsoka show may confirm this. Ahsoka's survival was ensured by a vergence in the Force during her duel with Vader, and the Force directly interfered to save her.
Skywalker presents Tano with her lightsabers, which now shine blue. While the lightsabers were in the custody of the Jedi, Skywalker took care of them, taking the opportunity to, as he saw it, "improve" them. The blades changed color to blue as a result.
Ahsoka's departure haunted Yoda for some time afterward; 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 Jedi Order. In fact, his guilt was so great that the Dark Side attempted to use it against him, but failed.
All things considered, it seems as though Ahsoka intentionally made the decision to not use both her lightsabers likely because the shorter shoto wouldn't have been as effective. An extended duel with Marrok and his fully ignited lightsaber likely necessitated Ahsoka to change tactics.
