Emily Swallow breaks down why the Armorer threw her weight behind Bo-Katan as the leader of Mandalore instead of Din Djarin in The Mandalorian. Although Din won the Darksaber at the end of season 2, the Armorer never treated him as the future leader of Mandalore, instead sending him on a quest to earn back his honor. However, in the fifth episode of The Mandalorian's third season, the Armorer announces that Bo-Katan will be the one to bring their people back together and retake their home planet.
