I figured Mando season 3 was going to be all about Bo-Katan trying to get the darksaber back and Mando being all, "just take it for God's sake, quit plotting to kill me while you do it!"
I never understood why they didn't just fight, and unbeknownst (sp?) to Bo-Katan, Mando throws the fight and she wins. He didn't kill for it, she shouldn't have to either.
