tldr (from that last post);
The Loth Wolf episodes of late S4 of Rebels established Kanan/Dume as the Grey Wolf, Ezra as the Prince, Sabine as the Princess, and Ahsoka as the Firebird in a very loose adaptation of the fairy tale Tsarevich Ivan, the Firebird, and the Gray Wolf.
Ahsoka S2 was code named “Firebird”, so it might be continuing the themes from those episodes while drawing on a different adaptation of the same story - The Firebird ballet - in order to make the Firebird the main Good Magic character and helper to the Prince and Princess (in the absence of the Grey Wolf).
Interestingly, the very most basic plot of The Firebird ballet is that the Firebird must defeat an evil wizard and his minions so that the Prince and Princess, who are in love, can marry and live Happily Ever After.
So if that is what the Ahsoka S2 code name means, then I'm all for it.
