Before leaving the world and telling his former Padawan how proud he was of her, Anakin left both Rex and a battalion of Clones to support Ahsoka, their helmets re-painted with Ahsoka’s Togrutan face markings, as a sign of affection and a reminder that Ahsoka had grown well beyond the young girl she was when she was first assigned as Anakin’s padawan. Those Ahsoka-homaging helmets
appeared on the new poster for Clone Wars’ return, so that touching moment will likely remain in the final version of the story line when we see it on Disney’s still-untitled streaming service.
What was unseen in that trailer, however, was another tidbit Filoni had previously discussed about this final story. Beyond the actual battle for Mandalore the story would’ve gone deeper into the background of what was happening to Rex and Ahsoka during the events of
Revenge of the Sith—specifically, how the two ended up surviving Order 66. The details ended up making their way
into E.K. Johntson’s Ahsoka novel (Rex had his inhibitor chip disabled after the events of
The Lost Mission’s haunting brush with the command, so Order 66 did not affect him—and after escaping the clones the duo faked their deaths and went their separate ways), but whether or not we’ll see them realized in this upcoming season remains to be seen.
