Star Wars: The Rise of Skywalker co-writer Chris Terrio says that the upcoming sequel will continue to build on the complicated relationship between the heroic Rey and the villainous Kylo Ren. The two are on opposite sides of the war between the First Order and the Resistance, but found themselves bonding through a Force connection and even briefly fighting on the same side in Star Wars: The Last Jedi.
The Last Jedi was a contentious entry in the Star Wars franchise that left fans divided, but perhaps the only thing that can set off fights as easily as praising or deriding The Last Jedi is bringing up the topic of "Reylo." This is a shorthand for a hypothetical romantic relationship between Kylo and Rey, which some fans are eagerly in favor of becoming canon and others consider to be an offensive concept. The pro-Reylo fans make the case that the two characters have an intense and fiery dynamic that could easily turn from hate to love, while the anti-Reylo side argue that Kylo is abusive and irredeemable, and it's certainly not Rey's job to save him from the dark side.
