Armorer kit reveal?

Except Boba openly admitted to being a mandalorian to Din to show the armour was his by right. To which Din accepted openly and recognized his rights to the armour. The armour that he had literally just taken from a man because he wasn't a mandalorian. But apparently to CG a flippant throwaway retort to Bo Katan for a snarky comment has greater authority than a scene played absolutely seriously and with evidence.
