There's no way Filoni was not involved in the finale.

Spoiler!

It's easy to write around Sabine giving her the Darksaber.

Bo-Katan broke tradition by accepting the Darksaber. There would be a built in conflict there with Death Watch. This could propel the reintroduction of the Armorer and Favreau's Paz Viszla. And there could be a conflict there between the Watch and the now lapsed Child of the Watch Din Djarin. Who actually did win it in combat.

Beyond that, Bo-Katan lost the Darksaber *and* lost the planet to the Empire. Wouldn't be a stretch to suggest that she lost the support or faith of some of the clans that came together to back her when Sabine handed the Darksaber to her.

Those are just a couple ideas that an idiot like me came up with. Favreau and Filoni are way better at this than I am, so I'm sure they already had it figured it out before they filmed it.
