Star Wars: 9 Burning Questions About Lando's Return In Episode IX
5. How Much Does He Know About Kylo Ren?
In Daniel José Older's novel, Last Shot, the section set after the events of Return of the Jedi chronicles Lando's interactions with Han and Leia as parents. Lando also interacts with a very young Ben Solo during this section, who lovingly refers to him as 'Unca Wanwo'. Lando has several nicknames for the young Solo over the course of the novel, the most adorable of which is certainly 'Little Starfighter'.
But all of this begs the question; how much does Lando know about what became of his Little Starfighter? In the decades since, Ben Solo has turned to the dark side and become a flat-out murderer. More importantly, he murdered Lando's long-time best friend, his own father, Han Solo.
Depending on where Lando has been, he may or may not have been privy to the information about Kylo Ren's true identity. At the beginning of Force Awakens, Lor San Tekka teases Kylo that he holds power because he knows his true name, which Kylo reacts to with rage. Since then, Kylo has ditched the helmet and is more open about his identity.
But, considering that Lando has been missing in action since before the events of Force Awakens, Lando might not even be aware that the now-Supreme Leade Kylo Ren is actually Ben Solo.
