OKAY OKAY I JUST FOUND THIS ERROR (since like, i have no life) 

okay, in the episode "Eminence" we get to see some faces and col armors of the death watch. One of my favorites (and i bet i am not the only one) is that one Mandalorian with the mythosaur painted in both, his helmet and chest armor. Here, have a picture of my sexy Mando Boy

okay so, here have the lil error

after making Jabba join them, Mando Boy is helping a dude over there, so he can stand up.

we can also see Bo there in the background. but.... there's a white helmet over there, see it?

then we can see Mando Boy talking with Bo, apparently. 

can't see it clearly? here, let me help you.
