There are so many questions that spring to mind when I see this. Are these Mandalorians in an official capacity or are they Death Watch? Or is it Death Watch that rules Mandalore since The Clone Wars? They’re probably serving the Empire since they’re attacking the crew.
It is pretty cool to see the Joe Johnston early Boba Fett work at play here, which I believe they are trying to evoke.
Thanks to Johnamarie on Twitter for the heads up!
