Unfortunately, fans didn't see a new trailer for the coming "Star Wars: The Last Jedi" at the recent Disney D23 Expo in Anaheim. But, viewers were treated to a behind-the-scene reel that gave a glimpse of different sequences teasing what was about to happen.

Fans saw their favorite characters having fun, seriously filming, on a training, and even talking about the film. There were also new creatures revealed. However, the scene that caught everyone's attention the most was seeing General Leia Organa's (Carrie Fisher) standing alone with a sad looking face.

A reunion that will never happen

An eagle-eyed fan from The Stupendous Wave, a YouTube channel for the "Star Wars" fans, revealed a major clue in that particular scene of General Leia Organa in "Star Wars: The Last Jedi."

The fan revealed that the unknown planet is now identified as Crait and the princess is actually not alone. Allegedly, she is with Rey (Daisy Ridley), who can be seen at the lower right most of the scene, with her new hair and costume. "Leia looks extremely somber," the fan said in the video. Now, the big question is what makes the wife of Han Solo (Harrison Ford) look so gloomy. Does it have a connection with her twin brother Luke Skywalker (Mark Hamill)?

The fan continued to say that Rey and Leia will be having their reunion on Crait, but Luke won't be there with them.

This might mean that the sibling won't be reunited at all in the entire film. Fans have been long waiting for the reunion of Leia, Luke, and Han since the sequel trilogy started. In fact, their get-together made "Star Wars: The Force Awakens" a strong film while their appearances were considered as one of the powerful moments in the movie.

However, with the untimely passing of Carrie Fisher and the death of Han Solo, it seems this will never happen.

A change of heart

Moreover, Making Star Wars.Net reported that Luke Skywalker will finally decide to leave Ahch-To in the coming "Star Wars: The Last Jedi." However, the Jedi Knight has no intention to join Rey and go back to the Rebels.

It has been said that he will go his own way to find Supreme Leader Snoke (Andy Serkis), so he could bring him down with his own hands.

There are also reports that the Jedi Master will be accompanied by his former apprentice and nephew Kylo Ren (Adam Driver). There are reports that he will help him to bring down the leader of the First Order. Allegedly, the former Ben Solo has a change of heart after a dramatic experience on Ahch-To at the end of the movie.
