Star Wars has just announced that The Mandalorian & Grogu will begin production later this year, and it raises the question of which characters will return for the next installment of Din Djarin's and Grogu’s story. The Mandalorian season 3 ended with Din Djarin officially adopting Grogu as his son and becoming a Mandalorian apprentice. It’s not entirely clear where the movie's director, Jon Favreau, will take the story, but more details will likely be coming out in the coming weeks and months. It also seems that The Mandalorian & Grogu will be taking the place of The Mandalorian season 4, though this has not yet been confirmed.
