You don’t mess with Sophie Turner‘s Jean Grey, but more importantly, you don’t mess with her Juul. On Tuesday night, the cast of the new movie X-Men: Dark Phoenix stopped by Jimmy Kimmel Live!, where they discussed some major spoilers about the film, including (alert!) Mystique’s death. While discussing the pivotal Dark Phoenix moment, Jennifer Lawrence revealed that right before they filmed her death scene, Turner’s dialect coach “took her Juul away,” causing the Game of Thrones alum to cry right as the cameras rolled. “It was so honest and real,” said Lawrence. “It was like the performance of the year.”

Host Jimmy Kimmel was quick to ask the Dark Phoenix cast about the death of Lawrence’s character, which was teased in the first trailer. “This is not a spoiler, but we know that Jennifer’s character Raven gets killed in the movie, but I wonder if that was emotional for anyone” said Kimmel. “Did anyone cry?” Lawrence explained that she did cry, but not over her own death. “I teared up a little bit watching Sophie in that scene,” she said. “Her reaction to my death was so raw.”

“It was so honest and real, and it’s because she really was crying,” continued Lawrence. “Because her dialect coach, right before the take, took her Juul away.” It’s no secret that Turner loves her Juul: shortly after Game of Thrones aired its series finale, the actress shared a behind-the-scenes photo of Sansa hitting her vape.

Lawrence’s story sent the audience into a fit of laughter, but Kimmel didn’t quite know what to make of it. “Oh, you’re electronic cigarette?” he asked, showing his age. “My vape, yeah,” replied Turner. “She started genuinely tearing up,” added Lawrence. “It was like the performance of the year. Amazing.”

“So that’s where you get your motivation? From your Juul cigarette?” asked Kimmel (god, who knew he was so lame). “It is, yup,” said Turner, explaining that her dialect coach knew how to get the best performance out of her. “That’s how to act. You take it away, and then you give it back. And that’s happy and sad,” said the Dark Phoenix star.
