Well, this is… unexpected. I really hope you’re telling the truth.
Even if you are, I think the personal decisions of people working on the Clone Wars show is different than what the canon has been saying for years. Even after the show was aired, all canon sources still said it was 3 years.
Canon sources said Ahsoka buried green lightsabers and that Rex, Gregor, and Wolffe all had their chips removed together.
Which canon sources trump which when they contradict each other? Ahsoka can’t age from when she’s introduced to where she ends up in three years. The final season alone takes place over the course of six months, Ahsoka’s walkabout taking place first, followed by The Bad Batch arc, followed by the Siege of Mandalore.
