The release of the Star Wars Rebels: Season 4 trailer in April revealed a very interesting giant wolf creature that led quickly to some speculation involving the fate of Ahsoka Tano.
Fans of Star Wars: The Clone Wars will remember the Mortis arc which featured Ahsoka, Anakin and Obi-Wan traveling to the Mortis Monolith and meeting the Father, Brother and Daughter. These three Force-users possessed unique powers including the ability to change their physical shapes and transform into animal forms. During the story the Daughter used the last of her life force to bring Ahsoka back from death.
With Ahsoka’s survival in Rebels seems clear what that meant for her future left a lot of doubt. The appearance of the giant while wolf in season 4 led some fans (including myself) to speculate that the wolf could be Ahsoka in a new form.
Dave Filoni closed out his birthday with a sketch that handily puts this theory to bed on Twitter (@dave_filoni). While it doesn’t discount that the wolf and the owl are associated with Ahsoka and perhaps Ahsoka is even commanding the wolf, it clears up that she is not the the wolf.
