Ooft, I’ve just realised that with my current structure, all of my season finales relate to the loss of Ahsoka and the topic of letting people go.

Cad Bane arc - Anakin says “I can’t lose you, Ahsoka.”
Geonosis arc - Anakin and Ahsoka clash with Luminara and Barriss about being ready to lose someone.
Onderon arc - Ahsoka learns to let go of Lux (another good reason to focus on him in a single season).
Ahsoka’s Fall - well, you know.
Siege of Mandalore - well, you know.

It rhymes.
