Jannah was a love interest for Lando.
Also, we need to give Rey’s father a third eye.
No, Jannah is Lando’s daughter that was kidnapped as a child, which is why he stayed behind on whatever the desert party planet was called.
The parts that actually make this clear were cut out of the movie, but that last bit was left in for some godforsaken reason (much like the parts with Finn wanting to tell Rey something that he never ends up saying, which was apparently supposed to be that he’s Force sensitive).
I saw the movie again today and decided I don’t know if I actually want a fan edit of it because I pretty solidly enjoy it all the way through, but I would very much like to see an extended cut that restores some of the cut subplots (especially Kylo learning about Palpatine on his own on Mustafar in the opening scene instead of putting that in the crawl and making the opening scene pretty much pointless).
