You can learn more about what happened to Finn in the year that passed between The Last Jedi and The Rise of Skywalker by reading the novel Resistance Reborn. But regarding the latter movie, while we’ve seen snippets of Finn in action with his Resistance allies (and wearing new threads), it’s difficult to put the pieces together and guess what will happen to him. Will he specifically deal a crippling blow to The First Order’s operations? Will he become a Jedi? Will he and Poe Dameron finally admit their feelings for one another? It’s all up in the air.
