Warning: contains spoilers for Star Wars #29!While it's a cultural institution today, Star Wars' original trilogy was far from a sure bet when it was first created, leading to some odd moments as plans changed between episodes - most infamously, Luke Skywalker and Leia Organa's initial romantic attraction. While Return of the Jedi would ultimately reveal them to be siblings, A New Hope implied Luke's attraction to Leia throughout, while the two kissed multiple times in The Empire Strikes Back, with further romantic moments ending up on the cutting room floor, as seen in the movie's deleted scenes. Their romance was also played-up in the original tie-in comics and novels, such as Archie Goodwin and Carmine Infantino's Star Wars #25, where the two again lock lips, and Alan Dean Foster's Splinter of the Mind's Eye, which shows Luke pining after Leia.
Ever since Return of the Jedi, Star Wars has reframed Luke and Leia's kiss as lacking real romantic intent - something Leia did solely to get a rise out of her real love interest, Han Solo. The kiss has become a running gag among franchise fans, with even actor Mark Hamill referring to it as an "innocestuous" kiss, since neither knew they were related at the time. Ultimately, it's a mostly amusing artifact created by the collision of an initial love triangle with the later retcon of Luke and Leia's relation, and yet over 40 years laters, Star Wars is still subtly taking the opportunity to subtly alter how fans see this detail of the films.
In Star Wars #29 - by Charles Soule, Ramon Rosanas, Rachelle Rosenberg, and Clayton Cowles - Luke, Leia, Chewbacca, Lando and Lobot find themselves on Spira as the guests of Amilyn Holdo. Holdo has gathered them to bid on some ancient Nihil technology that can be used to help the Rebellion, but she also admits that she hoped to offer her old friend and ally Leia some downtime before they attend the Imperial auction in disguise. Holdo says she wanted to offer Leia the chance to "soak up some sun near some handsome men," but she's quickly interrupted, as Leia declaims, "Lando? And Luke? Holdo, please."
Luke & Leia's Kiss Is Still Being Downplayed
The story takes places between The Empire Strikes Back and Return of the Jedi, meaning that Leia recently saw Han frozen in carbonite after professing her love for him. While it therefore makes total sense she's not in the mood to ogle her allies - and is still harboring a grudge against Lando - it makes little sense for her to speak derisively about Luke. Leia doesn't yet know they're related, and has a positive relationship with the handsome, war-hero Jedi. It's odd for her to go out of her way to scoff at the idea of finding him attractive except as a way for Star Wars to insist their relationship was always inherently platonic.
Star Wars Will Never Stop 'Updating' Its Story
Star Wars is a series known for its creators' attempts to go back and change inconvenient or outdated details, often by tampering directly with scenes, and it seems that spirit lives on in this quiet moment on Spira. Luke and Leia's initial 'love triangle' and kiss are essentially just in-jokes for Star Wars fans at this point, but by inserting moments to influence how the siblings' relationship is perceived, the franchise can only succeed in drawing attention to by far its most awkward moment.
