Here are some ‘Star Wars’ fan theories about Rey’s red lightsaber

SUMMARY
The newest teaser for "Star Wars: The Rise of Skywalker" contains a climactic moment that has fans buzzing: Rey wielding a double-bladed red lightsaber.
Disney debuted the new look at the upcoming movie, which hits theaters in December 2019, over the weekend at its biannual fan event D23 Expo. Now that the teaser is available on YouTube, fans are going wild with theories about Rey's possible turn to the dark side.
The Force-sensitive heroine has historically used a single-bladed blue lightsaber, which formerly belonged to Anakin and Luke Skywalker.
The "Star Wars" franchise has always taken lightsaber ownership very seriously, so it makes sense that fans are analyzing Rey's new weapon.
Rey is portrayed by Daisy Ridley.
"We take to heart the lesson that Obi-Wan tried to impart to Anakin: 'This weapon is your life.' We're not ones to lose track of lightsabers," Lucasfilm Story Group executive Pablo Hidalgo told Vanity Fair in 2017.
The movies have hinted at Rey's connection to the dark side before
In many ways, Rey is drawn as a parallel to Kylo Ren, a powerful servant of the dark side.
It's still unclear, however, whether their similarities are because Rey is drawn towards the dark side or because of Kylo's remaining connection to the light side. It could also be rooted in a secret familial relationship, since Kylo Ren was born Ben Solo, the son of Han Solo and Leia Organa — and eventual student of Luke Skywalker.
Writer Sarah Sahim also noticed that Rey's weapon on the poster for "The Force Awakens" is literally drawn parallel to Kylo's red lightsaber, creating a clear resemblance to the double-bladed red lightsaber.
The red lightsaber could mean that Rey will turn to the dark side — and fans are kind of into it
Subtle details from the teaser have led some fans to believe Rey will actually embrace the dark side in "The Rise of Skywalker."
Rey's theme music is played in a deeper, darker key, for instance. The footage is narrated by Emperor Palpatine and Darth Vader's breathing can be heard in the background just moments before "dark Rey" appears.
Even though a turn to the dark side would be detrimental to her heroic arc, many "Star Wars" fans were captivated by the image of "dark Rey."
Some believe the moment in the teaser is a "Force vision"
Responding to a fan on Twitter, Nerdist writer Lindsey Romain said it's "definitely a possibility" that Rey's red lightsaber moment is "a vision of what she could become" — though she wrote for Nerdist that she believes a real dark turn for Rey is more compelling.
Vanity Fair's Joanna Robinson is more convinced of the vision theory. Replying to Romain on Twitter, she attached a photo of Luke's Force vision from the Dagobah cave, where he sees his own face wearing Darth Vader's beheaded helmet.
The image of "dark Rey" could be a warning, showing the young hero what she could become and has to avoid.
The "dark Rey" image could also be Force vision for Kylo. It's possible that Kylo secretly fears that the dark side will win, or the image is being used by Palpatine to manipulate him — in Romain's words, "to taunt the poor boy about what could have been."
Another theory is that Rey, or a Rey clone, will be possessed by Emperor Palpatine or another Sith lord
We already know that Palpatine will play a major role in the upcoming film. In addition to narrating the trailer, he's shown as a massive and menacing presence on the newly released poster.
Palpatine could somehow possess Rey and force her towards the dark side.
Alan Johnson, the Director of Influencer Relations at WB Games, believes that "dark Rey" is one of many Rey clones.
"I still think Rey is a clone and the Sith version from the new 'The Rise of Skywalker' trailer is a clone that has been activated and possessed by Emperor Palpatine," he wrote on Twitter. "The vision she had in 'The Last Jedi' screamed 'clone' to me at the time."
