Han Solo once said, of Lando Calrissian, “Of course I don’t trust him. He is my friend, y’know.”
Wait, maybe you don’t know what that means. It’s simple, really.
‘Cause, see, Han and Lando were friends way way back but they hadn’t spoken in years because Lando thought that Han had cheated at cards.
So Han needed Lando’s help to escape the Empire and repair the Millennium Falcon (Han’s spaceship), but it turned out Lando had already betrayed Han to Darth Vader and arranged to have Han and Chewbacca tortured and Han sold to the bounty hunter Boba Fett, the droid C-3PO broken down into parts, and Princess Leia turned over to Darth Vader for nefarious purposes.
So Han was right not to trust Lando – but it was already too late when he said that.
That’s how Han got frozen in carbonite.
Luckily Lando had a change of heart and, at the last minute, helped Chewie, C-3PO and Leia escape from Cloud City, and even eventually helped rescue Han from the clutches of the vile gangster Jabba the Hutt, to whom Han owed money.
Man, I miss those movies.
But, still, bottom line: Lando shouldn’t have been trusted until he’d earned Han’s trust again.
Really, I shouldn’t have to explain this. It’s elementary. But some people aren’t as interested in a classical education these days.
