Before the film was released, there was certainly plenty of speculation surrounding the meaning of the title for Episode VIII - "The Last Jedi". Now that it's out though, I'm not sure we ever really got an answer for the question - Who is/are the eponymous "Last Jedi"?
On Crait we get this exchange:
KYLO REN: ...The Resistance is dead, the war is over, and when I kill you, I will have killed the last Jedi!
LUKE SKYWALKER: Amazing. Every word of what you just said was wrong. The Rebellion is reborn today. The war is just beginning. And I will not be the last Jedi.
Kylo considered Luke to be the last Jedi, but when Luke disagrees, the camera cuts to a close up of Rey's face as she uses the Force, as if to say that Rey is in fact the last Jedi.
The only problem with that is that the international translations of "The Last Jedi" clearly use the plural meaning of Jedi. So Rey can't be the "Last Jedi" from the title as she's just one person. So who are the last Jedi?
