Probably only for a scene. I heard he was pretty expensive to generate. But with the rest of the Rebels squad in there, I imagine he’d have to.

Yeah, she's still got Ezra's (from the Rebels finale when he left it with her as he went to confront Thrawn), and has at least some training with it from Kanan when she had the Darksaber.

I believe I even heard her call Ashoka “master”. That piqued my interest quite a bit.

As far as we saw in Rebels, she only trained with Kanan. Sabine only found the Dark Saber well after the events at Malachor, which was the last we really saw of Ahsoka in Rebels until the bits in the last few episodes, so didn't train with Ahsoka. I'm a little puzzled by the whole "walking away from you" and "Master" bits in the trailer, since they didn't really have a relationship other than fellow insurgents in Rebels.

Anyway, I would expect Sabine to have lightsaber skills similar to Bo-Katan's, given that Bo-Katan likely trained with it more than Sabine did (though, on the other hand, Sabine had some instruction from an actual Jedi). She has her Mandalorian tricks (like the cable gun, flame thrower, etc.) that should make it a more interesting fight with a Force wielder, but she'd be outmatched.

Dunno. But they seem to be leaning quite heavily into the "I'm no Jedi," thing. All of the lightsabers none of the dogma? I think it's an interesting way to go considering how big the sick-of-jedi-sith contingency is these days.

Rebels, find a watch list if you want to skip the more kiddy first season but it's really all worth watching. Then just know that ahsoka made a cameo in the book of boba Fett where she is trying to find admiral thrawn, and that she knows luke and maybe helped him with his school for a time but it's not clear on that

I’m going to guess that they try to make the characters and history make sense to audiences that have only seen the live action series but it looks like a direct continuation of Star Wars Rebels.
