It's funny. I keep hearing people mentioning Ahsoka's theme, I've never quite caught what it was supposed to be. So I went to YouTube and just listened to the theme without any visuals, and now I can't not hear it when I watch the show. I'm actually huming it to myself right now.
If it helps to contextualise,
here's a little video of a few key times it's popped up over the years. Though it omits probably my favourite creative use of it, which is in
the final sequence of 'Twilight of the Apprentice'.
I remember back when this aired there was a massive debate over whether Ahsoka was alive, or even visible on screen or not (which still seems like a bonkers thing to argue against on the face of it) and here's me like
"guys, Kiner is screaming her theme through this whole thing, and it's not a funerial dirge or sentimental farewell. How is this not all about Ahsoka still being alive?"
Speaking of music helping to contextualise story; notice how in
Sabine's fight with Saxon that it's not
Sabine's theme, that plays at first when she get's back up from being knocked down, but
the force theme? Also, listen when she decides not to Anakin Gar Saxon to death and instead says
"That might be the Mandalorian way, but it's not my way. Not anymore." Again, it's the force theme playing.
Dave's been working up to her converting to Jedi philosophy for a while, and it's not just this episode and 'Trials of the Darksaber' that made it overt. It goes back to at least 'The Protectors of Concord Dawn'.
For me the final clincher was the convors in TotDS; while Ezra is training with Sabine there's a pair of them watching on, perched on some coral . . . then a third swoops into frame and sits by them. Filloni has used these birds as a metaphor to signal to the audience what's going on since the 'Padawan Lost' arc in Clone Wars.
In all this, I think some fans either forget, or don't understand that force sensitivity isn't meant to be a super-power of a select few; it's a spectrum that
everyone is on. The force exists within and is created by
all living things, and everyone (with cellular biology) has midichlorians to commune with it. Being strong in the force and having a high M-count is just like having a natural talent for something, but talent alone only gets you so far without discipline and perseverance. Which conversely is also how one can overcome a lack of natural talent. There's plenty of highly skilled people out there that were useless in their chosen vocation until they worked their arse off to get better, just as there's plenty of natural prodigies that either never fully applied themselves, or took their talent for granted and were overtaken by those who were far more motivated.
Moreover; using the force isn't what defines a Jedi. It is after all a religion, so what matters isn't whether you can float rocks with your brain, it's about philosophy. How to live your life. How to be a good person. In that, Sabine has more of an advantage that I think she even realises because at her core, she's a deeply selfless person and that is a hallmark of Jedi philosophy. Remember as a cadet she sacrificed everything for her family, her people, and for Mandalore to correct her own mistake. A more selfish person wouldn't have done that.
