Rise Of Skywalker: 13 Visual Dictionary Revelations That Change EVERYTHING
3. Jannah Is Lando's Daughter
Saving that strange scene at the close of the movie, one plot point at a time.
So, when Lando takes one look at Jannah and says "let's find out" in regards to who she is, it's in fact not a return of Solo-style "Pimp Lando", but the character finally being reunited with his daughter.
The evidence is manifold. First up, the Dictionary details Lando's exploits post-Episode VI, saying that he "attempted to start a family, but tragedy struck and his infant daughter vanished."
It's then said the First Order were behind the kidnapping, which lines up with Jannah's comments that she was a child taken from her home; a stormtrooper called "TZ-1719", who lay down her weapons to escape, like Finn.
Furthermore, the characters' ages pretty much line up.
Jannah is noted as early twenties, while Lando's daughter was taken when she was 2 years old. The second Death Star was destroyed 30 years before Starkiller Base, leaving an eight-or-less year gap for Lando to decide on settling down to start a family, post-Return of the Jedi.
