There was one scene in The Mandalorian season 2 where Din Djarin's face was going to be revealed, but actor Pedro Pascal himself stopped it from happening. One of the most intriguing and iconic things about Din's character since his debut has been his strict helmet rule, a strong part of his creed that other Mandalorians in Star Wars history have never followed. Bo-Katan Kryze, Sabine Wren, and other notable Mandalorians were always comfortable in removing their helmets, which has made Mando's strict rule become an even more interesting thread of his story.
