Last month, the title of Episode VIII was revealed and we scoured over the possibilities. It turns out that the most simple explanation is the answer, there are more than one Jedi.
Apparently, “The Last Jedi” is not one Jedi such as Luke Skywalker, but rather the order of Jedi. The title is the plural form of Jedi, and we know this thanks to the official Italian, Spanish, and French “Star Wars” Facebook and Twitter accounts.
Those titles are all plural, so this means that there are more than one Jedi.
Now, are Luke and Rey the last Jedi, or are there more Jedi out there. Wish I had an answer for you.
