I mean, what is a True Mandalorian? I mean, I highly doubt she is going to start following the creed as the Children of the Watch say it. A small part of the episode I keep going back to in my mind is the pog soup bit. Din doesn't know what it is, but to Bo-katan, it is a childhood staple. And I highly doubt the Armorer will ever accept Bo-katan. Bo-katan is sounding a lot more like her sister this episode, which kind of makes sense with all that has happened to her and Mandalore over the years.
I do laugh at the people being like "Din saw the Mythosaur, he is the Mandalore". Like, he saw nothing. Man did not see where he was going and passed out while sinking in his armor.
