They finally released the title of Star Wars Episode VIII: The Last Jedi. Some people have speculated on who this last Jedi is, but I think we already know who it is. Before Yoda died in the Return of the Jedi, he told Luke Skywalker that he would be the last of the Jedi after he died. After his failure to resurrect the Jedi Order, I think Luke lost his confidence in his ability to train Jedi. As a result, I think Luke Skywalker intends to always be the last Jedi. When he went to the first Jedi Temple, it looks like he went there so that the Jedi could end where they began, which is fitting. Normally, Jedi go to die on Mustafar, but the first Jedi Temple is a nice choice to end the Jedi. Unless Rey can convince Luke to train her, it looks like the Jedi will die with Luke. However, because there must always be balance in the Force between light and dark, if the Jedi die out it is possible a new light side order will replace them just as the Knights of Ren replaced the Sith. Either way, I look forward to finding out if my analysis is accurate.

The Last Jedi is also a title from a Star Wars EU book that I guess Disney rendered iffy canon. Haven’t read it, but I think it’s a continuation or conclusion to the Coruscant Nights series of Star Wars books. Kinda weird Disney takes its title for the movie from it, but then again there are multiple Star Wars stories that reuse “The Clone Wars” subtitle that are mostly different from each other, so I guess it makes sense.
