YMMV / Star Wars Rebels S3E05 "Imperial Supercommandos"

• The Producer Thinks of Everything: Rau left behind his helmet back in "The Protector of Concord Dawn" when he made a run for it. As there have previously been errors regarding helmets being left behind in an area that isn't likely to be accessed again (such as "Blood Sisters", which ended with Sabine's helmet either supposedly having been blown up or left with Ketsu) or Hammerspace, Rau is never given time to find it, but instead finds a lone helmet on the ground from one of his men and keeps it.
