I like that they actually had Mandalorian font in the background screen when Viszla was talking with Dooku.
Also, when the one Death Watch, who jumped from the balcony, was dying, they actually had him speaking in Mando'a. He even uses the phrase "Darasuum Kote," which is Mando'a for "Eternal Glory," made popular in the song from the Republic Commando games.
Also, a "Duchess of Mandalore?" Really? Are you serious?
I know they're saying the planet isn't Mandalore and that it's actually a planet in the Mandalore system called Kalevala, but that is never referenced in the episode at all. But, Concordia actually is supposed to be a moon of the planet Mandalore, so which is it, Mandalore or Kalevala?
So, was the moon's name that the Death Watch was based on, "Concordia," supposed to be an homage to Concord Dawn? Jango Fett's homeworld and also located in the Mandalore system
And where were the rangefinders on the Mandalorian helmets? It's not like they couldn't draw them on there. Captain Rex's rangefinder is based off of Mandalorian helmet designs. Oh well.
