The relationship between Daisy Ridley's Rey and Adam Driver's Kylo Ren was one of the more interesting in The Force Awakens. They're the new trilogy's two main characters, and their first scene together was one of the highlights of the 2015 blockbuster.
It's the scene in which Kylo Ren's attempt to torture Rey backfires as the latter realises her latent force powers, and uses them to vocalise Ren's insecurities when he attempts to read her mind and she instead delves into his.
The pair later clash in the film's climactic lightsaber duel, with Rey coming out the victor.
As the two new force-users of the trilogy, their relationship is set to develop in December's sequel The Last Jedi. Ridley and Driver have offered some insight into how this will go down.
Speaking to Entertainment Weekly, Driver said: "[Kylo] has been aware of this ability in himself from such a young age, and I don't think there's a lot of people around him who are on the same level.
"I think that there is something familiar there [in Rey], as well as something to be feared, or something ... that he can't quite place."
At the end of The Force Awakens, Kylo Ren kills his father Han Solo, which, from Ren's perspective, was a "hopeful" act according to Driver. "If anything he has justice. I think he's surprised by how he would feel after Han Solo. He's hoping for hope. He's hoping for clarity."
Driver said Ren's turn to the Dark Side stemmed from a sense of feeling lost, coupled with his parents' heroics and their broken relationship. "Looking around and not seeing yourself and not identifying with what's around you, I think, affects how we behave."
Rey is also a lost individual when we find her in The Force Awakens. She's looking for meaning and purpose, and could well teeter on the brink like Kylo if she doesn't.
"The Resistance is really not that much to her," Ridley says, referring to the band of good guys taking on the evil First Order. "I mean, she's been left her whole life, and very quickly is eager to sort of help other people, which is wonderful. She wants to be part of something. I mean, everyone wants to be part of something."
At the end of the last film, Rey finds Luke Skywalker (Mark Hamill) who she hopes will offer her the sense of purpose and place she's after. He's reluctant to mentor her however, sensing her raw potential power.
That power reminds Luke of Kylo Ren, who he taught before Ren turned to the dark side.
Director and writer Rian Johnson also chipped in about Rey's journey, but what he says could also apply to Driver's character.
"This is very much about Rey trying to figure out how she fits into all this, much like any of us as we're growing up, as we're transitioning from childhood into adulthood," Johnson said. "You're going meet people who you think are going help who don't. And help is also going come from unexpected places."
Could Rey and Kylo Ren find common ground as two young people struggling with who they are, their potential and their place in the galaxy? We'll find out when The Last Jedi is released on 14 December.
