Sabine isn't a given, she could always be off doing Ezra related stuff or what have you, but with the rest of the cast seemingly gathering, it sure does feel like a logical appearance, doesn't it?
Ahsoka, Fett, Bo-Katan, the possibility though not promise of Rex. Sabine makes so much sense. This is looking to be a really loaded season, in terms of Star Wars returns.
And despite all the awesome I just want them to confirm my Armorer = Rook Kast theory.
