SALT LAKE CITY — The teaser trailer for “Star Wars: The Rise of Skywalker” included a small moment from “The Last Jedi,” that you might have missed, which might change how you watch the new trailer.

“The Rise of Skywalker” shows the sequel trilogy’s Rey (Daisy Ridley) training in the middle of a desert. The trailer then shows some of the “Star Wars” heroes — like Finn (John Boyega) and Poe Dameron (Oscar Isaac) — as well as the trilogy’s villain, Kylo Ren (Adam Driver).

Luke Skywalker (Mark Hamill) voice plays over the entire trailer as he talks about the importance of legacy before he gives way to silence.

"We've passed on all we know. A thousand generations live in you now. But this is your fight. We'll always be with you," Luke says.

He added, "No one is ever really gone."

Then, the Emperor’s evil laugh can be heard.

Watch below.

His final line, “No one is ever really gone,” coupled with the Emperor’s laugh, hints at the return of the villainous Palpatine. But, given the title “Rise of the Skywalker,” immediate thoughts would suggest it's possible that Luke Skywalker, Anakin Skywalker or even Shmi Skywalker could return in the final film.

But that might be the case.

See, that last line — “No one is ever really gone” — is actually first featured in “Star Wars: The Last Jedi” in an exchange between Luke and his sister, General Leia Organa (Carrie Fisher), and it totally changes how you watch “The Rise of Skywalker” film.

At the end of “Last Jedi,” Luke arrives to save the day, appearing with a freshly trimmed beard. He looks down at Leia’s hands, which hold the dice from Han Solo’s ship, the Millennium Falcon. Luke arrives just as Ren and the First Order descend upon the Resistance’s base.

“I held onto hope for so long, but I know my son is gone,” she said, referring to her son, Ben Solo, who was consumed by the dark side and became Kylo Ren.

“No one is ever really gone,” Luke says.

You can watch that scene below.

So does the line in “The Rise of Skywalker” trailer really mean someone is coming back? Or does it imply that Kylo Ren is heading for redemption? In "The Last Jedi," Luke uses the line to say that Kylo Ren might not be totally gone from the light side of the force. But in "The Rise of Skywalker" trailer, it implies characters might be returning.

We’ll probably learn more when new trailers for the film drop, and when the film arrives in theaters on Dec. 20, 2019.

According to The Daily Beast, the scene in "The Last Jedi" had some important behind-the-scenes context as well. It was “meant to fortify Leia for what’s to come, but which also, unintentionally, comforts those still reeling from Fisher’s death," according to The Daily Beast.

And it’s the last scene Luke and Leia will probably have on stage together.

“Last Jedi” director Rian Johnson said the scene meant a lot on set, too, according to The Daily Beast.

Comment on this story

“It’s bizarre because, you know, obviously we didn’t know that it was gonna be a farewell scene,” he told The Daily Beast on the day of "Last Jedi’s" release. “And it’s odd because I remember when we were shooting the Luke-Leia scene, it felt like church on set. It was usually a jovial set, you know, a really happy, bouncy set. And that day, everyone was just quiet and just watching these two.”

“It was like a hush over the whole set,” he says, “it really did feel like church. I remember there being a weight to the whole thing and we all just felt like, we’re seeing something really special happen. In a way that it never, ever was on the set for us. There was, very weirdly, weight.”
