Yeah, I'm not a fan. I loved her in Rebels, but I can't figure out why she even wants to be a Jedi? She's a pretty awesome Mandalorian; just get more guns. Stop torturing yourself trying to sprout magical powers you don't need.
Then she threatened to shoot the map...while it was in her hand?! And then just gave it to the bad guys? Wtf???
Something is off, maybe writing/direction with her character this season but she was well in rebels?
Hoping she gets better as Ahsoka did during clone wars
It's not that unusual for humans to get stuck in a stage of development if something traumatic happens to them during that time.
They've almost outright stated that Sabine was traumatized by Ezra's sacrifice at the end of Rebels. She has also lost all of her family at this point.
