Summary
- The Force Dyad, a bond between Rey and Kylo Ren, was an interesting concept left unexplained in The Rise of Skywalker.
- The Force Dyad requires both the light and dark sides, which the Sith couldn't replicate due to their devotion to the dark side.
- The Force Dyad should have been the central focus of the movie, exploring the relationship between Rey and Kylo Ren and their potential for balance.
The Force Dyad could have been the key to making Star Wars: The Rise of Skywalker a much better movie. The epic conclusion of the Star Wars sequel trilogy may have grossed over $1 billion worldwide, but it's not really regarded as a success. Lucasfilm tried to pivot after the controversy surrounding Star Wars: The Last Jedi, and they overcompensated badly. The Star Wars sequel trilogy cast did their best, but they simply couldn't overcome a lackluster script that desperately attempted to push every nostalgia button.
What makes this particularly disappointing, though, is the fact Star Wars: The Rise of Skywalker actually had a lot of interesting ideas in it. One of the most intriguing was the Force Dyad, which finally explained the bond between Daisy Ridley's Rey and Adam Driver's Kylo Ren. Although the movie itself simply tossed the idea in, subsequent tie-ins have fleshed the Force Dyad out a great deal, turning it into one of the most interesting ideas in the franchise. Here's how the Force Dyad could have saved Star Wars: The Rise of Skywalker.

A legend among the Sith, the Force Dyad is a mysterious naturally-created bond between two Force-sensitives. As seen in Charles Soule and Will Sliney's The Rise of Kylo Ren, the Force Dyad seems to have been created by the will of the Force itself at the moment Ben Solo fell to the dark side. The Force Dyad was boosted when Kylo Ren unwisely attempted to penetrate Rey's mind in Star Wars: The Rise of Skywalker, as explained in Jason Fry's novelization of Star Wars: The Last Jedi:
"Kylo had retreated at finding Rey in his head. [He] had practically fled from her. But that had not been the end of that strange, sudden connection. She had seen more – far more. Somehow, almost instinctually, she knew how he accessed some of the powers at his command – even though she didn't understand them. It was as if his training had become hers, unlocking and flinging open door after door in her mind."
Rae Carson's novelization of Star Wars: The Rise of Skywalker subtly hints there's a reason neither Jedi nor Sith could have ever created a Force Dyad. It describes their bond as being "refined in the fire of mutual searching, shared grief, rage and hate, but also of compassion and empathy." In other words, the Force Dyad requires both the light side and the dark. The Sith had attempted to duplicate the Force Dyad for countless generations, but their devotion to the dark side meant they could not do this.
