What Happens to Din Djarin in The Mandalorian Season 2?
After being entrusted with the care of the Child at the end of season one, Din Djarin spends the second season attempting to fulfil his promise to reunite the Child with "its own kind" — aka, the Jedi. As he follows every clue he can find to track down the elusive remaining Jedi, he winds up getting involved in the politics of the Mandalorian diaspora, discovering that the people who raised him were actually part of a splinter sect, and that one woman, Bo-Katan Kryze, is attempting to reclaim the throne of Mandalore and restore their society. He also crosses paths with Jedi Ahsoka Tano, who tells him how to reach out to other Jedi, as well as a still-alive Boba Fett and Fennec Shand, who, when Baby Yoda is kidnapped by Moff Gideon, join forces with him on a rescue mission.
Ultimately, Din Djarin and Moff Gideon have their long-awaited face-off, which ends with Din Djarin winning — and accidentally winning possession of the Darksaber that Bo-Katan needs. He's last seen bidding Grogu a tender (and helmet-less) farewell as he's whisked away to train as a Jedi under Luke Skywalker himself.
